大掺量矿渣石膏水泥基复合材料的水化特性
Hydration Characteristics of Cement-based Material Containing High-volume Slag and Gypsum
摘要
Abstract
The hydration characteristics of cement-based material containing high-volume of slag and gypsum(SG)were studied by testing compressive strength,using XRD and TG-DTA technology.The results show that the early strength of SG is far lower than that of ordinary Portland cement(C),while the strength development is very fast especially at the stage of 7-28 d.The strength at 28 d reaches to the level of 42.5 MPa and the strength of SGs except for SG-4 paste at 90 d are higher than that of C.With the increase of clinker content,early strength of SGs increase,while no follow the rule on later-age strength.In later hydration age,active Al2O3 and active SiO2 in slag powder participate in the reaction and improve the compressive strength.Hydration products of SGs is mainly for C-S-H gels and AFt,there is a large amount of Ca(OH)2 replaced of AFt in C.Clinker content has great influence on hydration product quantity,while little effect on the kinds of hydration products and hydration product quantity in later-age.关键词
