Procedure for Concrete Compression Test
WebJan 1, 1996 · Results also indicate that the natural aggregate concrete has less compressive strength, less porosity and higher water absorption compared to that of concrete made with crushed aggregate. This is true for 0.4, 0.45, 0.5, and 0.55 water cement ratios. ... Water absorption test of concrete was carried out according to … WebMar 31, 2024 · While traditional concrete normally has a compressive strength ranging anywhere from 2,500 to 5,000 psi, UHPC can have a compressive strength of up to 10 times that of traditional concrete. After just 14 days of curing, UHPC has a compressive strength of 20,000 psi. This number increases to 30,000 psi when fully cured for 28 days.
