Abstract:
Concrete is a material which develops strength with age. The amount of strength acquired in any given period of time depends upon a number of factors to be dicussed in this paper. In the early days concrete dud not gain strength rapidly and it was found necessary to wait 28 days after making it before testing. Because of this practice of testing at 28 days, it was generally considered necessary to wait 28 days before using the conrete. During recent years tests have been made on concrete at ages earlier than 28 days so that it is possible now to use concrete structures sooner than was customary previously.
