The invention provides environment-friendly wall cement mortar without chromatic aberration, which is prepared from the following components in percentage by weight: 20 to 30 percent of cement, 2 to 4percent of rubber powder, 0.1 to 0.2 percent of water reducing agent, 0.01 to 0.2 percent of sodium sulfate, 7 to 12 percent of volcanic ash, 2 to 7 percent of calcium powder, 2 to 5 percent of silicon dioxide aerogel, 10 to 15 percent of color paste, 1 to 7 percent of aluminum oxide and the balance of aggregate, totaling 100 percent. Compared with similar cement mortars, the environment-friendlywall cement mortar without chromatic aberration is shorter in drying time, free of shrinkage, small in deformation coefficient, higher in bending strength, tensile strength and breaking strength andhigher in adaptability.
本发明提出了一种环保无色差的墙面水泥砂浆，按重量比包括如下组分：水泥20‑30％、胶粉2‑4％、减水剂0.1‑0.2％、硫酸钠0.01‑0.2％、火山灰7‑12％、钙粉2‑7％、二氧化硅气凝胶2‑5％、色浆10‑15％、氧化铝1‑7％和剩余量为骨料，上述组分含量之和为100％。本发明的环保无色差的墙面水泥砂浆相比同类水泥砂浆干燥时间更快、无收缩、变形系数小，抗弯强度、抗拉强度和抗折强度更强，适应性更强。
