Acquire an grip of the relation between closure compressive strength and other strengths such(prenominal) as splitting plastic strength, flexural tensile strength and resembling mental block compressive strength. The test conducted is according to hatful 2, CS 1:1990 Testing Concrete. (ii). Apparatus Compressive testing machine ( foresee 2.1) Calipers - digital calliper (Figure 2.2) Weighing equipment - electronic balance (Figure 2.3) Figure 2.

1 Figure 2.2 Figure 2.3 (iii). Procedures 1.Cubes from the curing tank were removed. 2.Surface water and girt was wiped immerse with a damp cloth. 3.The cube for faults and damages such as broken edge was visually inspected. 4.The three cube dimensions were flip over w ith calipers. If they differ from nominal va! lue of the cube by a specified value (1mm on width and 2mm on height), at a lower place size or oversized would be recorded as appropriate. 5.The cube was weighted. 6.Test machine platens were wiped with a dry cloth. 7.The cube was placed on the lower platen of the test machine with the restive as-cast top surface of the test cube vertical non in contact with the platens. 8.The appropriate loading regulate for the cube tested...If you want to get a full essay, gild it on our website: BestEssayCheap.com
