养护温度对核防护用地聚合物早期强度影响研究

Experimental Study of Curing Temperature on the Early Strength of Nuclear Protection Geopolymer

分析了养护温度、养护时间及砂子种类对核防护用地聚合物强度性能的影响,并进行了一系列的温度响应实验,实验结果表明,养护温度对核防护用地聚合物的早期强度影响巨大,温度越高,早期强度越高,强度提升越快;发现养护温度对养护时间6.5小时以上地聚合物样品的影响不大,且不能改变地聚合物的最终强度;掺合湖北砂的地聚合物样品强度最高,性能最好。

The influence of curing temperature,curing time and the type of sand on the strength of the geopolymer was analyzed,and temperature response tests were conducted. Experimental results showed that the curing temperature had an significant influence on the early strength of geopolymer that the higher the curing temperature was,the higher the early strength was and the faster the strength enchanced; the curing temperature had a little effect on geopolymer cured for more than 6. 5 hrs and couldn＇t change the ultimate strength of the polymer; the geopolymer blended in Hubei sand presented the highest strength.
