Nov 27, 2012· Strength and Porosity Relationship for Pervious Recycled Aggregate Concrete Following the earlier discussion, it is clear that influence of age, specimen size and shape, binder material type on compressive strength of pervious concrete are not significant when compared with the influence of porosity of concrete.
Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results, conformity can be checked as per the relevant standards.
