采用酸性环境下加速试验的方法，研究了材料组成对砂浆耐酸性能的影响。对不同水泥品种、灰砂比和外加剂在各个腐蚀阶段砂浆的质量变化和抗压强度变化进行比较分析。结果表明：在pH=2的酸性环境下，普通硅酸盐水泥砂浆和高抗硫酸硅酸盐水泥砂浆的耐腐蚀能力比快硬硫铝酸盐水泥砂浆强；灰砂比大时，砂浆的耐酸性有所改善；在1年的侵蚀龄期内，掺憎水剂的砂浆相比掺阻锈剂与密实剂的砂浆强度下降率小。
採用痠性環境下加速試驗的方法，研究瞭材料組成對砂漿耐痠性能的影響。對不同水泥品種、灰砂比和外加劑在各箇腐蝕階段砂漿的質量變化和抗壓彊度變化進行比較分析。結果錶明：在pH=2的痠性環境下，普通硅痠鹽水泥砂漿和高抗硫痠硅痠鹽水泥砂漿的耐腐蝕能力比快硬硫鋁痠鹽水泥砂漿彊；灰砂比大時，砂漿的耐痠性有所改善；在1年的侵蝕齡期內，摻憎水劑的砂漿相比摻阻鏽劑與密實劑的砂漿彊度下降率小。

This paper studies on the effect of material in the acid resistance of the mortar by the experiment in acidic environment. The experiment uses different varieties of cement, cement-sand ratio and additives to compare the quality and compressive strength in various stages of various stages of corrosion. The results showed that: In the acidic environment of pH = 2, ordinary cement mortar cement mortar and anti-acid corrosion resistance faster than a hard and strong sulfur aluminate cement mortar; it would improve acid resistance when the cement-sand ratio is larger;in the one year period, the decreased rate of mortar strength mixed with water repellent is lower than mixed with rust resistance and compacting agent.
