路用聚合物改性水泥混凝土(PMC)性能与应用研究

Performance and application of polymer modified cement concrete (PMC) in road construction

聚合物改性水泥混凝土即具有水泥混凝土的高强度又具有沥青混凝土的高柔性,由于其优良的路用性能,聚合物改性水泥混凝土在路面工程领域得到了广泛的研究与应用。分析探讨了聚合物对水泥混凝土的改性作用以及改性机理,并总结了应用在混凝土中各种聚合物的要求,总结了近年来聚合物在水泥混凝土路面工程中的应用研究现状,最后结合实例具体介绍了聚合物改性混凝土的在路面工程中的施工方法。

The polymer modified cement concrete has the cement concrete＇s high-intensity and the asphalt concrete＇s high-flexibility.On account of its great performance, the polymer modified cement concrete has widely used in the application of highway.The effect of the polymer is analyzed in the cement concrete and its mechanism, and the general requirements for polymer latexes as cement modifiers.We generalize the present research and application status of polymer modified cement concrete are generalized with introduction of constiuction method about the polymer modified cement concrete.
