Abstract
In order to study the properties and mechanism of cement paste mixed with anti-cracking silicone waterproofing agent,the fluidity test,hydration heat analysis,shrinkage deformation test,mercury intrusion test and SEM analysis of cement paste were carried out.The results show that when 5％anti-cracking silicon waterproofing agent is added,the fluidity of the paste reaches its maximum value of 268 mm,the hydration heat decreases by 43％in 1 day,and the expansion rate reaches about 0.085 mm when the curing period is 14 days,when curing at 40℃ or higher,the longer the curing life,the greater the expansion,the lower the calcium hydroxide and the smaller the grain size of the cement paste,and more flocculent calcium silicate colloids and ettringite crystals appear on the surface.关键词
