摘要:Maturity methods are used to predict strength or other mechanical properties of a concrete mixture for a given moisture availability as a function of time and temperature. Temperature sensitivity of a mixture is characterized by datum temperature for the Nurse-Saul (NS) method, a...

摘要:Standard and nonstandard penetration-resistance tests were conducted on cement paste, mortars incorporating that paste, and concretes incorporating those mortars. Simultaneously, the diminishing ability to consolidate the concrete with a vibrator, impress a footprint into th...

摘要:The influence of datum temperature and activation energy on the accuracy of strength prediction via the maturity method was investigated by an iterative search method to find values of those parameters that minimized the difference between predicted and measured compressive stren...
