改性砒砂岩强度和水化产物的试验研究
Experimental Study on the Strength and Hydration Products of Alkali-Activated Pisha Sandstone
摘要
Abstract
In order to solve the problem of lacking of check dam engineering materials in Pisha sandstone areas, the slag which contains a large amount of active aluminum silicon, activity and calcium oxide was used as a modifier. The microstructure, hydration products and water resistance and compressive strength of modified Pisha sandstone were analyzed. The results show that a) the compressive strength of modified Pisha sandstone increases with the increase of the dosage of slag. In the age of 90 d, using 40% of slag, 1.5% activater and 4% auxiliary activater, the compressive strength of modified Pisha sandstone can be improved to 52 MPa;b) the optimum content of activator is 1% and;c) the hydration products of modified Pisha sandstone are C⁃S⁃H gel, Si⁃Al gel and calcium carbonate crystal.关键词
