The influence of fast-setting/early-strength agent on high phosphorous slag content cement

摘要

In this paper, the influence of fast-setting/early-strength agent on the high-content phosphorous slag cement (PHSC) was studied by the strength tests, setting-time test, pore-structure test and XRD analysis. The components and hydration of fast-setting/early-strength agent had also been studied. Test results showed that the use of fast-setting/early-strength agent could solve the problem of poor early properties of PHSC. In addition, industry by-products had been fully utilized.
