2021-5-1 Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.

Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc’. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.

2016-11-28 compressive strength decreases. The percentage reduction in compressive strength of 25 % and 50 % replacement level is 11.76 % and 26.95 % respectively. Based on the results, the fall of compressive strength and density of concrete is gradual when the replacement increases. As the percentage of CCTA increases, workability decreases.

On the other hand, the compressive strength test shows an increment in the compressive strength of the cube as the day’s increases with 28 days recording, the highest value of 4.78 N/mm 2 and 4.44 N/mm 2 for 10% and 25% replacement of coarse aggregate respectively. While that of 50, 75 and 100% were very low compared to the former results.

The compressive strengths were recorded by crushing the cube at 7, 14, 21 and 28 days and it was found that performance of concretes with 0% and 25% replacement of natural aggregate by recycled aggregate were quite similar to concrete without replacement but with 50% and 75% replacement, the strength of concrete was decreased.

1988-11-1 The results obtained clearly show that palm kernel shell is a lightweight aggregate. The aggregate crushing value test performed on the shell aggregate gave a value superior to that of crushed granite. It would be wrong however, to assume on the basis of the result that the strength of the shell aggregate is higher than that of the crushed
