concrete compressive strength of different ratio

Jul 26, 2021 Results of the compressive strength tests are shown in Fig. 8. In general, the compressive strengths of all mixes decreased steadily with increasing plastic replacement ratios. At 3-days age, the compressive strength of PET10%, PP10% and PET20% were higher than that of control mix by 22.4%, 9.2%, and 6.6%, respectively.

e) Compressive Strength (After 7 Days) Table 8 shows different compressive strength values at different aggregate cement ratios. Using this, graph between compressive strength and A/C ratio is shown in Fig.10. It is clear from the Fig.10 that as A/C ratio increases compressive strength of pervious concrete decreases.

Compressive Strength of Concrete. The compressive strength of concrete is a measure of the concretes ability to resist forces trying to compress or push the concrete together. Concrete is very strong in compression, particularly in comparison to the concretes strength in tension and flexure which are relatively weak.
