    Ultrasonic pulse velocity methods is one of the non-destructive testing methods. Commonly the compression test was used to determine the compression strength of concrete. Laboratory works had been carried out at heavy concrete laboratory to obtain the result for both non-destructive and destructive test. By using concrete cubes of sizes 100 x 100 x 100 mm and subjected to water curing for 7, 14, 21 and 28 days to obtained desire result for Ultrasonic Pulse Velocity and Compression test. Ultrasonic Pulse Velocity were initially done before the Compression test. The data obtained from each test has been evaluated and tabulated in this report. From this research, the variation between predicted strength and experimental strength for Ultrasonic Pulse Velocity testing was identified; the higher the pulse velocity, the higher the predicted strength and lower times passes by pulse velocity, the higher the predicted strength.

    Concrete prisms are being test with flexural testing by different percentage volume of steel fibres. The total number of 24 prisms were made which contain 3 %, 6 % and 9 % of steel fibres respectively. This only consist experimental results. Specimens used in this study using a prism mold of 100 mm x 100 mm x 500 mm. Eighteen prisms will be added with a layer of 10 mm of steel fibre using slurry method. All of the samples were tested using flexural testing to determine the maximum loading. The highlight scope of this research is to evaluate the physical behavior of Slurry Infiltrated Fibre Reinforced Concrete in term of maximum load and cracking pattern. The results of the study were also compared with concrete without steel fibres. However, the workability of the concrete decreased as the number of steels fibre increase. The maximum load was obtained by the lowest percentage of steel fibre (3%).

    The aim of the study is to study the physical and mechanical characteristics of Slurry Infiltrated Fiber Reinforced Concrete with fiber percentage volume of 5% and lower. For the testing of physical characteristics of the concrete, density test been conducted. For the testing of mechanical characteristics, compression test used to determine strength of concrete sample. The density of Slurry Infiltrated Fiber Reinforced Concrete increased when the usage of steel fiber percentage volume increases from 1% to 5%, nevertheless when compared to density of ordinary concrete, ordinary concrete is denser. For the significant of study, the mechanical properties of Slurry Infiltrated Fiber Reinforced Concrete, compressive strength increased when the fiber content increases from 1% to 5% percentage volume.

    Since the cost of cement increases and the pollution to environment due to greenhouse effect are becoming more serious year by year, thus, dolomite fines subjected to replace the cement in concrete mix as it has lower cost compared to cement. In this research, the replacement of cement with dolomite fines carried out in this study is 0%, 5%, 10%, 15% and 25%. The grade of concrete a designed to be 30. A total of 45 units of 150 mm x 150 mm x 150 mm concrete cube and 30 units of cylindrical concrete sample with diameter of 150 mm and height of 300 mm designed in this study. The properties of concrete sample in terms of compressive strength, splitting tensile strength, ultra-pulse velocity and rebound hammer test for various percentage replacement are determined in this study. The tests on concrete sample carried out at the age of 7-days and 28-days. Overall, its shows that 10 % replacement of cement with dolomite fines provided the highest strength to the concrete in terms of compressive strength and splitting tensile strength.

    Since the cost of cement increases and the pollution to environment due to greenhouse effect are becoming more serious year by year, thus, dolomite fines subjected to replace the cement in concrete mix as it has lower cost compared to cement and it is obtain directly from the Earth ground without any manufactured process. Dolomite fines also shows almost similar physical and chemical properties as cement. The various replacement of cement with dolomite fines carried out in this study is 0%, 5%, 10%, 15% and 25%. The grade of concrete sample designed to be 30. The properties of concrete sample in terms of physical characteristics; slump, density and water absorption for various percentage replacement are determined in this study. In this study, it shows the dolomite fines are lightweight aggregate compared to the cement and the water absorption of is lower compare to that of the control concrete.

    The use of waste products as partial replacement for the material in concrete can help to reduce the environmental and economic problem. Coconut shell (CS) is one of the agricultural waste that suitable to use as and coarse aggregates replacement due availability of CS which not only can help to decrease the cost of the concrete and reduce the environmental problem, it also can maintain the properties of the concrete. In this study, the compressive strength of the concrete has been chosen to be investigated. Three different types concrete cube have been casted in this study; 0, 10%, 15%, 20% of CS to replace for coarse aggregates. The size of the cube samples to be casted is 100 x 100 x 100 mm and were cured for 7 and 28 days. The study shows that the optimum percentage for CS concrete is 10% due to in this percentage of replacement, it gives the highest compressive strength value compare to other percentage at 28 days.
