【 摘 要 】

A technique is proposed for determining the critical length of a main crack in concretes at different loading rates. A composition of light, heat-resistant fiber-reinforced concrete of increased strength and crack resistance, which does not require heat treatment, has been developed. The effect of high temperatures on the change in the strength and fracture resistance of heat-resistant heavy and light concretes was studied.
