摘要:
研究了不同养护温度(10 ℃、20 ℃、30 ℃、60 ℃、90℃)对偏高岭土基地质聚合物凝结硬化性能的影响和对反应物的NH+4交换容量的影响.结果表明:在保湿条件下,随养护温度提高,偏高岭土基地质聚合物的凝结时间缩短,抗压强度发展速率减慢;在低于20 ℃室温并保湿条件下,偏高岭土基地质聚合物24 h不凝结,掺入矿渣粉能促进其凝结;但是,随矿渣粉的增加,反应物的NH+4交换容量下降.
Abstract:
The effects of different curing temperatures (10 °C, 20 °C, 30 °C, 60 °C, 90 °C) on the coagulation hardening properties of metakaolin base polymers and the NH+4 exchange capacity of reactants were studied. The results showed that under moisturizing conditions, the setting time of metakaolin base polymer was shortened and the development rate of compressive strength slowed down with the increase of curing temperature. Under the condition of room temperature below 20 °C and moisturizing, the metakaolin base polymer did not condense for 24 h, and the incorporation of slag powder could promote its coagulation. However, with the increase of slag powder, the NH+4 exchange capacity of the reactants decreased.
