Study on Optimization Proportioning Experiment and its Hydration Mechanism of Composite Cementing Material

摘要：

　　This article aims at the accelerating characteristic of coal filling material.We scientifically made a series of proportion on composite-cementing material through uniform design with Portland cement,sulpho-aluminate cement and gypsums.After having testing the capability of this,we found that some certain composite-cementing material strength has been improved,both early and later strength.Furthermore,we also continually analyzed the hydration products and microstructure of composite-cementing material,then determined that early hydration products were mostly ettringites and later were C-S-H-centered and CH-centered gel.
