Influence of Superplasticizers on Early Age Drying Shrinkage of Cement Paste with the Same Consistency赖俊英,ZHANG Lifeng,钱晓倩,SHEN Chong,ZHANG JinjianCollege of Civil Engineering and Architecture, Zhejiang University摘 要:The influence of superplasticizer(SP) on the early age drying shrinkage of cement paste with the same consistency was investigated......
and AlCl3·6H2O as starting materials, NH3·H2O as precipitant and H2O2 as complexant. The effects of adding H2O2 and microwave drying on the preparation and properties of ADYSZ were investigated.... During microwave drying process, the moisture of wet precursors is selectively heated. Quick expansion of steam vapor within the wet colloidal particles causes the aggregations burst into numerous tiny......
