Mechanical Properties of Manufactured-Sand Concrete after High Temperatures
Keyword(s):
In this paper, to study mechanical properties of manufactured-sand concrete after high temperatures, experiments on the residual strength of manufactured-sand concrete were carried out under high temperatures in which raw materials performances and concrete mixture proportion were considered. The mechanism of elevated temperatures on residual strength was theoretically discussed, and the calculation formula of residual strength was given. The results indicated that with the increasing of temperature, the mass loss was small while the reducing of strength and the elastic modulus of manufactured-sand concrete were significantly.
