摘要: 用对比强度法和石灰吸收试验研究了玻璃粉的胶凝活性。结果显示,掺玻璃粉胶砂7d强度较低,但掺量在20%以下时,28d和56d活性指数均在80%以上。玻璃粉对56d胶砂抗折强度有明显改善作用,随掺量增加,抗折强度增大。玻璃粉加入Ca(OH)饱和溶液和水泥养护溶液中,溶液pH值随龄延长不断下降,有较高的火山灰反应活性。

Abstract: The cementitious activity of the glass powder was studied by contrasting mortar strength and the lime absorption test.The results showed that the 7d strength of mortar with glasspowder was lower,however the activity index of both 28d and 56d were above 80%  when the dosage was below 20%.The 56d flexural strength of mortar significant improve when mixing glass powder.the fexural strength of mortar increases with the amount of glass powder increases.When the glass powder was added into the Ca(OH)  saturated solution and the cement curing solution.The pH of the solution continuously decreases with age,it show that the glass powder has highly pozzolanic activity.
