Through contrasting and analyzing the test phenomenon as well as the data at elevated-temperatures and after elevated-temperatures,the residual flexural strength of recycled concrete was studied,meanwhile,the varying characteristics and the relationships between the residual flexural strength of recycled concrete and exposed temperatures were analyzed.

Experimental investigation on the effects of moisture content and fiber on both explosive spalling and residual compressive strength of high performance concrete(HPC) after exposure to high temperatures was presented.

This paper presented the performance of shrinkage compensating concrete exposed to high temperatures, concluding residual compressive strength and Cl--penetrability performance.

Test of concrete under high temperature and the study of residual compressive strength after high temperature;

In designing and calculating,several measures such as using the indexes of residual shear strength of sliding-belt soil and double-parameter method etc are ta.

relation between normal stress and peak shear strength, relation between normal stress and residual shear strength, and relation between normal stress and frictional shear strength), the shear deformation properties of two kinds of cement concretes, the characteristics and description of shear faces.
