Potassium Silicate Potential for Earthen Relics Protection in Moist Areas
摘要
Abstract
Potassium silicate (PS) is applied in the earthen relics reinforcement project of northwest arid areas, with wide acceptance. But no significant evidences prove whether PS can protect the earthen relics in moist areas and its potential. In laboratory, specimens are made by compaction and the water contents controlled at 13% , 17% , 19% , 21% and 25%. Then,3%PS is infiltrated into specimens with different water content to reinforce them. After direct shear and consolidation test,conclusions are found; ( 1)Pervious infiltration velocity and quality of PS infiltration are different from different water content, some regularity: pervious infiltration velocity and quality of PS infiltration decrease as water content increases; (2) PS has some certain reinforcement effect on earthen relics in moist, proved by the increased resistance ability against compression and shear strength after reinforcement; (3) Although protection effect of PS varies with gravimetric water content, the optimum locates between 19% and 21%. These test results and conclusions provide some data support for the protection practice on earthen relics with PS in moist areas.关键词
