Effects of Temperature on concrete Compressive Strength during curing time.
https://youtu.be/-MUeEDaQkvI What is Curing of Concrete?? Curing is a process during which a chemical reaction (such as polymerization) or physical action (such as evaporation) takes place, resulting in a harder, tougher or more stable linkage (such as an adhesive bond) or substance (such as concrete ) Why do Concrete Comprehensive Strength Testing required to be Tested at 28 days?? Concrete gain 60 % -65% of specified strength in 7 days And 90% of Specified Compressive Strength in 28 days. So,It is recommended as per IS 456 -2000 to Test verification of Strength of concrete as mentioned above at 7 days & 28 days respectively to checking the variations limit of strengths . We should do proper curing by considering the environmental conditions, type of structural members, atmospheric temperature ?? Maintaining the proper temperature also plays a vital role in concrete as mentioned, it should not be colder than 5 0 C. Concrete is kept moist for at least 28 days. Recommend
