不同石料类型对水泥稳定碎石无侧限抗压强度的影响分析
Effect of Cement Stabilized Macadam Unconfined Compressive Strength with Different Rocks
摘要:
通过采用工程现场钻孔取芯和室内试验方法，对比分析了以石灰石、炉渣、磷渣和钢渣碎石为集料的水泥稳定材料无侧限抗压强度，得到四种不同水泥稳定材料之间的强度关系，验证了不同石料类型的水泥稳定碎石在工程中应用的可行性。研究结果表明：磷渣碎石部分替代和钢渣碎石全部替代石灰碎石的效果最好，而水泥稳定炉渣碎石则表现出逊于普通水泥稳定碎石的无侧限抗压强度。采用不同类型的石料部分或全部替代石灰碎石制备水泥稳定碎石在工程中是可行的。
Abstract:
The unconfined compressive strength of cement stabilized macadam with limestone, slag, phos-phorus slag and steel slag contrasted and analyzed by field and laboratory test. The results show that partial replacement of phosphorus slag macadam and full replacement of steel slag macadam are the best, while cement stabilized slag macadam shows lower unconfined compressive strength than ordinary cement stabilized macadam. Using different types of rocks replaced limestone to prepare the cement stabilized materials was feasible.
