strenght of concret

strenght of concret,High-Strength Concrete - The Portland Cement AssociationHigh Strength Concrete In the early 1970s, experts predicted that the practical limit of ready-mixed concrete would be unlikely to exceed a compressive strength.strenght of concret,WHY WE TEST CONCRETE SRTRENGTH AFTER 28 DAYS?From above table, we see that, concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days and 99% strength in 28 days.What is Concrete Strength and what are the factors affecting it?Strength of concrete is directly related to the structure of the hydrated cement paste. Air in concrete produces voids. Excess of water in concrete evaporate leave.
