SUMMARY OF METHODS TO DETERMINE THETHERMAL DILATION COEFFICIENT (TDC) OF CEMENT -BASED MATERIAL AT EARLY-AGE

摘要

The present paper firstly summed up the actuality of the measurement of early TDC of cement-based material, then analyzed some factors, which may result in measuring errors. Finally a novel apparatus and its application for measuring the TDC of cement-based material at early-age are presented. Using this new method, TDC of cement-based materials can be measured rather accurately from early-age, with adequate consideration of temperature history.
