ABSTRACT: In the construction process, it is always important to know the concrete compressive strength. The recommended procedure to ensure the concrete strength is to perform cylinder test. Test result of concrete cylinder at 28th day, represents the characteristic strength of the concrete that has been prepared and cast to form the concrete work....

Online TalkingAnalyses of test results show that the compressive strength and splitting tensile strength are related, and an increase in one generally is similarly reflected in an increase in the other. The commonly accepted 0.5-power relationship between the compressive strength and the splitting tensile strength was found to be inaccurate at all ages....

Online TalkingAfter 10 years, the compressive strength decreased or remained essentially the same. MacGregor (1983) used the same study and formulated an equation of the relation between compressive strength and age; in the case of 28-day-specified compressive strength of concrete, this is equal to 281.5 kg/cm2 (27.6 Mpa)....
