Evaluation of Thermal Expansion Coefficient and Autogenous Shrinkage Properties of High Strength Mass Concrete Using Retarder AgentBusiness
초록
Autogenous shrinkage of high-strength mass concrete is affected high temperature history. So to evaluate autogenous shrinkage of high-strength mass concrete accurately, thermal expansion in it should be removed. In this study, compensated autogenous shrinkage was calculated after gathering thermal expansion coefficient at early age experimentally. As a result of the study. Autogenous shrinkage of mass specimen (300
