摘要
研究不同聚灰比条件下SBR改性乳化沥青对水泥砂浆工作性能和力学性能的影响,试验结果表明在水泥砂浆中加入适量的SBR改性乳化沥青,能够使其工作性能和力学性能得到明显改善,脆性降低、柔性增大,当聚灰比在10％～15％时改性效果较好.
This paper studies the effects of SBR modified asphalt emulsion polymer-cement ratio under different working conditions and mechanical properties of mortar cement, test results show that adding an appropriate amount of cement mortar SBR modified asphalt emulsion, can make significant performance and mechanical properties improvements to reduce brittleness, increased flexibility, when 10% to 15% of modified poly better than gray.
