【摘要】 AGS是由矿渣、熟料、石膏、少量激活剂磨制而成的一种新型粒料土稳定结合料。其凝结时间长、抗折强度高 ,具有微膨胀性。本文对 AGS稳定粒料土性能进行了研究 ,结果表明 :用 AGS稳定粒料土强度比 42 5 #水泥高 2 0 % ,并且其劈裂抗拉强度、CBR值和抗裂性均优于 42 5 #水泥稳定体的相应指标 ,与 42 5 #水泥相比 ,达到同等强度可节约用量 2 0 %。 AGS稳定粒料土的延迟成型时间可长达 8～ 1 2 h。更多还原

【Abstract】 AGS, a new granular soil stabilizing binder, is made from slag、Clinker、gypsum and a little activator It has long setting time ,high bending strength and expansibility. The performance of AGS is studied in this paper The results show that the strength of AGS stabilized granular soil is 20% higher than that of 425 # cement stabilized granular soil, and tensile splitting strength、CBR value and crack resistance of AGS stabilized granular soil are superior to that of 425 # cement stabilized granular soil. The amount of AGS is 20% lower than that of 425 # cement in the same granular soil strength. The delay time of AGS stabilized soil can reach 8~12 hours.更多还原
