Abstract
When concrete exposed to low temperatures, the free water in the concrete is freeze. If the pressure developed exceeds the tensile strength of the concrete, the cavity will dilate and rupture. It cause expansion and cracking, scaling and crumbling of the concrete. In this study, to prevent such damage, five different types of form were used. Concrete was poured into each form, cured for 7 days at temperature of -10℃. To measure the temperature history, two thermocouples were installed on each of the inside and outside. And to measure the compressive strength, collected core from each form. The maturity is formed by temperature history. The maturity and the compressive strength has a correlation.
