Relation Between Density and Compressive Strength of ...

2020-7-31  Concrete must has to ensure satisfactory compressive strength and durability. The mechanical properties of concrete are highly influenced by its density. A denser concrete generally provides higher strength and fewer amount of voids and porosity. Smaller the voids in concrete, it becomes less permeable to water and soluble elements. So water absorption will also be less and better durability is expected from this type of concrete. In this paper an experimental program conducting on compressive strength, density, absorption capacity and percent voids of hardened concrete is described. The variation of these properties with maturity of concrete was main focus of this experiment. Comparison is made between two types of concrete’s property test results. One of them is lightweight concrete made with crushed brick (BC) as primary coarse aggregate. Crushed brick is a locally available construction material in Indian subcontinent. Another type of concrete

Testing High-Strength Concrete Compressive Strength

1993-7-1  Abstract: Testing high-strength concrete (HSC) for compressive strength puts into doubt a certain number of concrete testing practices. First, most testing laboratories are equipped with loading capacity machines inadequate for testing 150 x 300-mm (6 x 12-in.) specimens, thus limiting HSC specimens to 100 x 200 mm (4 x 8 in.) in size.
