    Technology in concrete is rapidly developing to improve the quality and properties of concrete. One of the many recycled materials is worn-out tyres. Currently, the use of tires is very widespread considering the use of vehicles that increase from time to time. Piles of discarded tires can cause a lot of damage to the environment. So, by using steel wire waste (SWW) as new fiber reinforcement in concrete and with the combination with carbon black (CB), it is hoped that, by doing this, not only it could improve the quality of concrete, but also preserves the environment. Therefore, the objective of this research was, to identify the properties of fresh concrete with the addition of SWW and CB, and also to investigate the physical and mechanical properties of hardened concrete, incorporating of SWW as additional fiber reinforcement and CB. For fresh concrete, workability using a slump test was conducted. Several tests were carried out on the properties of hardened concrete. Among them were compressive strength, flexural strength, splitting tensile strength, and water absorption. The physical appearance of the concrete has also been examined and recorded. There are four batches of concrete which consist of one control batch and three batches of concrete with various weights of SWW which are in the portion of 300 g, 600 g, and 900 g, and the weight of CB is maintained at 300 g for all batches. For workability, all concrete batches with the addition of SWW and CB show acceptable workability. For the case of the density of fresh concrete, samples containing 900 g addition of SWW have the highest density which was 2520 kg/m³, as expected. Results for water absorption show that the lowest value is contributed by the control sample which was 7.6%. For compressive and flexural strength, 300 g addition of SWW has the highest value which was 28.52 MPa for compressive strength and 7.52 MPa for flexural strength. Lastly, for splitting tensile strength, the highest value was also obtained when 300 g addition of SW was added which was 5.4 MPa. To conclude, SWW and CB can be added to concrete to obtain comparable strength of concrete. However, some modifications could be made to both recycle materials to improve concrete performance.

    Municipal solid waste (MSW) landfills are one of the major source of hydrogen sulphide (H2S) which is the offensive odours potentially creating annoyance in adjacent communities. This project focuses on H2S emission from landfills in Perlis, Malaysia. Landfill gas (LFG) samples were collected and analyzed accordance with NIOSH method 6013. The mean concentrations of H2S in Kuala Perlis Landfill and Padang Siding Landfill are 210.68 ppm and 242.85 ppm respectively. High concentrations of H2S may be a concern for employees working on the landfill site. These results indicate that workers should use proper personal protection at landfill when involved in excavation, landfill gas collection, and refuse compaction. The formation of H2S most likely to be contributed by the biological conversion of sulfate from gypsum-rich soils and landfill wastewater treatment sludges by sulfate-reducing bacteria (SRB) which can utilize dissolved sulfate as an electron acceptor. H2S is conveniently detected by hand held analyzer, such Jerome meter, landfill gas analyzer. In the organic range, in the ease of detection range in the dispersion rate within the landfill site, the monitored H2S gas form a very noticeable concentration with the travelling wind direction. It proved that the dispersion rate of H2S are suitable as tracer to detect route of travelling in a certain distance.

    Due to the large amount of combustion ash being thrown into landfills, which can lead to environmental pollution, new alternatives to construction materials can be developed by utilising this combustion ash as a part of the main raw materials, while at the same time helping to preserve natural resources in the concrete manufacturing industry. Generally, using new waste materials will eventually affect the engineering properties of concrete. Therefore, the main objective of this study is to analyse the engineering properties of concrete containing combustion ash as a partial replacement for ordinary Portland cement (OPC). CA can be classified as combustion bottom ash (CBA) and combustion fly ash (CFA). CA is tested for its chemical compositions using X-Ray Fluorescence (XRF), and its four main compositions, which are silica, alumina, iron, and calcium, are examined and discussed extensively. Other testing for the property of CA includes Scanning Electron Microscopic (SEM) and specific gravity testing for coarse aggregate. To produce sustainable concrete from waste, several tests have been conducted to determine the engineering properties of the concrete, such as compressive strength, flexural strength, and splitting tensile strength. Results show that CA, which consists mainly of silica dioxide, contributed to the strength of concrete. SEM images show that CBA has a porous structure with an angular and rough texture, whereas CFA has more rounded particles, which influence the overall compressive strength. Furthermore, it was discovered that as the proportion of CBA utilised increased, the compressive strength, flexural strength, and splitting tensile strength of the concrete improved. Based on the results of the testing, CBA is suggested for use as a supplementary cementitious material in concrete.

    Coal bottom ash (CBA) is a co-combustion product material, which may cause hazards to human health and the environment. Rapid growth in technology causes the increase of CBA waste and this situation led to a waste disposal crisis. Reuse waste material as an alternative material instead of natural materials can led to sustainable and environmentally friendly construction. The main objective of this study is to determine the physical properties of CBA and its suitability to be used as replacement material in civil construction. The physical properties test conducted in this research were aggregate impact value test, aggregate crushed value test, flakiness and elongation test. The results show that the ability of CBA to resist sudden shock and repeated load was lesser than natural aggregate (NA). The differences of aggregate impact value (AIV) and aggregate crushing value (ACV), between NA and CBA were 50.4% and 48.9%, respectively. In addition, CBA has higher amount of flaky and elongated particles compared to NA. The flakiness index value for NA and CBA were 7.12% and 26.10%, respectively while the difference value of elongation index between NA and CBA was 37%. However, even though the properties of CBA were not as good as NA, the results for ACV and the flakiness index of CBA meet the minimum requirement of Jabatan Kerja Raya (JKR) Standard Specification which indicates that CBA has potential to be used in civil construction.

    The issue related to disposing waste material from industries has become one of the major environmental, economic and social problems. However, natural resources consumed worldwide, while at the same time increased amount and type of the waste material has resulted in waste disposal crisis with a growing consumer population. Therefore, the solution to this crisis is recycling waste into useful materials. In this project, Municipal Solid Waste Incineration (MSWI) by product which is bottom ash is used as partial replacement in cement. However, its properties as water absorbent become the issue for concrete strength. This research paper is to investigate the influence of superplasticizer on performance of cement-bottom ash concrete and designed for strength of 20 MPa at 28 days will be evaluated for its early stage properties. Superplasticizer is used to reduce water in cement while keeping up a consistent workability. The percentage of replacement in cement is by 0% (control), 10% and also 10%, 20% and 30% with addition of 0.30% by weight of cement of superplasticizer. In order to achieve the objective, few tests were carried out including slump test, density test, water absorption test and compression test. The result of this research indicates that 10% of replacement of bottom ash with superplasticizer shows highest compressive strength with 33.215 MPa with density 2417 kg/m3, water absorption of 1.41% and 122 mm for slump loss at 28 days. This study proved that the addition of superplasticizer can increase the workability and strength of concrete containing bottom ash as replacement for cement.

    A by-product of the mushroom industry, spent mushroom substrate (SMS) is primarily made of lignocellulosic agricultural waste. SMS contains cellulose (38-46.6%), lignin (25-34.5%), and hemicellulose (19-27.7%) and is nutrient-rich. The primary objectives of this study included the characterization of SMS, analysis of lignocellulosic content prior to and following pre-treatment, analysis of the effects of various NaOH concentrations with varying molarities (1.0 to 5.0 Molar), and analysis of surface morphology using a scanning electron microscope (SEM). The result that comparison between untreated and treated sample The result for untreated are contain high amount of lignin from 23.85% to 27.39% and for treated are amount reduce from 20.6% to 23.85%. The difference of NaOH concentration from 1.0 to 5.0 Molar, so the best pre-treatment is alkaline pre-treatment from 1.0 to 3.0 M are the best concentration to treat SMS sample from alkaline pre-treatment and proved sodium hydroxide pre-treatment as an effective method to reduce the hemicellulose and lignin contents. Images clearly showed how the pre-treatment could alter the biomass's structural makeup and distort it, increasing the surface area that was open to enzymatic attack. The pre-treated SMS's surface had numerous sporadic pores and cracks. The study's findings demonstrated that SMS from the P. sajor-caju species has the potential to provide a new source of glucose for bioethanol production.

    Each year, a large amount of quarry dust (QD) waste is disposed into landfills. This waste material was obtained as a by-product during the production of aggregates through the crushing process of rocks at the quarry site. The increasing value of waste will have a significant impact on health and the environment. Reusing such wastes by including them into building materials is a practical answer for the pollution problem. Therefore, this research was to observe the possibility of quarry dust to be included in a concrete mix. The quarry dust has been used as a partial replacement for cement proportion at different levels of replacement (25%, 30% and 35%). Quarry dust was used as the main material in this project to measure the effectiveness of concrete performance. In this research, the quarry dust composition was determined by using X-Ray Fluorescence Spectrometer (XRF). From the x-ray fluorescent spectrometry test result, the quarry dust displays some similar characteristics with the Ordinary Portland Cement (OPC) where it comprises a high composition of Calcium Oxide (CaO). Research were done to determine the optimum percentage of quarry dust in concrete. The result shows that 25% of quarry dust and 75% of cement is the best percentage that can be used in concrete mixture to reach the standard strength. From an economic point of view, the proposed optimum concrete mix was found to be the most economical with the reducing of RM 33 per 1 m3 of the concrete mixture. The results indicated that the quarry dust waste could be utilised as cement replacement to produce durable and resilient concrete. These materials could be an alternative low-cost material for concrete and at the same time provide a new disposal method for the waste.

    This study focused on the reclamation of ash from incineration process and development of new artificial lightweight aggregate (LWA) that have comparable properties with existing natural coarse aggregate. The main objective of this study is to examine potential use of recycled municipal solid waste incineration (MSWI) ash as raw material in LWA production with a method of cold-bonded pelletization. Two types of incineration ash which is bottom ash (BA) and fly ash (FA) were collected from Cameron Highland Incineration Plant, Malaysia. The properties of BA and FA are studied by means of X-Ray Fluorescence (XRF) and microstructure of these ashes were inspected using Scanning Electron Microscope (SEM). The properties of BALA and FALA produced in this study is examined including loose bulk density, water absorption and aggregate impact value (AIV). From the results of both types of artificial LWA, the lowest loose bulk density of BALA is BALA50 with 564.14 kg/m3 and highest is at 831.19 kg/m3 . For FALA50, lowest loose bulk density is 573.64 kg/m3 and highest is 703.35 kg/m3 . Water absorption of BALA and FALA is quite similar with one another in with the value of 23.8% and 22.6%, respectively. Generally, FALA have better qualities of LWA comparing with BALA with lower bulk density and water absorption and can be categorized as strong aggregate. In summary, reclamation and reutilization of incinerator ash has generated acceptable qualities for artificial LWA. Both types of BA and FA shown a great potential to be recycled as additional materials in artificial aggregate production.
