Title: Research on the Low-purity Limestone Used as Cementitious-grout Materials
Abstract: The reaction between various limestone and glassof different properties in near ambient temperature has been studied.The result showed that some low-purity limestone and certain transitionalconcentrated water glass(Be o=45~48) were the better for quicker reaction,shorter setting time and higher cementing strength.The reaction product was identified as some hydrate calcium silicate gel.Therefore,a new type of cementitious material,especially used as a new grout material,has been developed.It is,compared with other current grout materials,a typicalgreen andenvironment-friendmaterial with very low cost and good comprehensive properties.The performances as grout material of limestone and water glass were studied.
