The invention provides a saltpetering-preventing cement mortar and a maintenance method. The cement mortar comprises the following components: ordinary Portland cement, sand, ultrafine silicon powder,attapulgite powder, bentonite and cellulose ether. The surface of a paving material is immediately covered with a plastic film after the hard paving construction is finished. The saltpetering-preventing cement mortar has the advantages that the cement design strength and the economy can be ensured, the saltpetering is inhibited in the later period of cement mortar; and the film covering method after construction can accelerate the development of the internal structure of the cement mortar and accelerate the improvement of the closing amount of internal ducts of the cement mortar, so that thesaltpetering phenomenon is fundamentally reduced.
本发明提供了一种防泛碱水泥砂浆及养护方法，水泥砂浆的组份包括普通硅酸盐水泥、砂、超细硅粉、凹凸棒粉、膨润土、纤维素醚；在硬质铺装施工完成后，马上于铺装材料表面覆盖塑料薄膜。本发明所配置的防泛碱水泥砂浆可以在保证水泥设计强度和经济性的基础上，降低水泥砂浆后期的泛碱现象，而施工后的薄膜覆盖法，可以加速水泥砂浆内部结构的发育，加速提高水泥砂浆内部孔道的闭合量，从而从根本上减轻泛碱现象的发生。
