摘要
通过试验探讨了羧基丁苯聚合物改性混凝土的强度、韧性及内部孔隙结构。结果表明:聚合物改性混凝土的力学性能较好;孔隙分布分析表明:羧基丁苯聚合物在混凝土中交织成网状胶膜,是混凝土的内部孔隙分布有所改善,能够降低混凝土的渗透性,从而使混凝土的抗氯离子等损害的能力有了适当的提高。
Through test the paper examines strength,toughness and interior pore＇s texture of carboxy butadiene styrene polymer - modified concrete. The examined results show that the mechanical property of polymer - modified concrete is better. The analysis of pores distribution indicates the polymer of carboxy butadiene styrene mingles to be a network jelly membrance in concrete,improving the distribution of concrete interior pores, lowering the permeability of concrete and increasing the ability of concrete to resist injury from chroride ion.
