| 摘要： | This report proposes a new method for determining concrete maturity based on kinetic models of cement hydration employing short-term measurements of heat generated during hydration using isothermal calorimetry. The method uses Computer Interactive Maturity System software. The interrelationship of heat generation, maturity and strength development can be used to predict thermal conditions and strength gain in concrete during curing. The results are tabulated. The work includes field studies of a bridge pier and highway slabs, and curing tables which include variants such as concrete thickness, weather conditions, and concrete temperature. |
