Papers by Keyword: Super-High Strength Concrete

Abstract: Volume change of super high strength and high performance concrete with different binder-aggregate ratios and different curing conditions were investigated in this paper, and the volume changes of cement paste and mortar were also tested. The results indicated that the change of cement paste was much higher than mortar and concrete under the same curing conditions；the curing condition has a obvious influence on the volume change; there was a moisture swell for the water curing concrete; the specimens with limestone powder have smaller volume change than those specimens without limestone powder. The volume change mechanism was explained, and the effect of limestone powder on the volume change was also discussed.

Abstract: Durability of C100 concrete in Shenyang WAN XIN Hotel engineering including long-term mechanical properties, dynamic modulus of elasticity, and chloride ion resistance was tested and analyzed. Test results appeared that C100 concrete had very good density and extremely good durability. Simultaneously we suggest improving the evaluation method to test the durability of super-high strength concrete in order to enhance the evaluation level effectively. It will provide one according of durability to apply super-high strength concrete.
