Cement-based self-leveling ground leveling material with high fly ash content
The invention discloses a cement-based self-leveling ground leveling material with high fly ash content. The concrete is prepared from the following raw materials in percentage by weight: 2.5 to 27.5 percent of ordinary Portland cement, 1.5 to 2 percent of instant sodium silicate powder, 2 to 5 percent of light calcined dolomite powder, 0.5 to 2.5 percent of calcium oxide, 0.5 to 1 percent of calcium hydroxide, 0 to 25 percent of sulphoaluminate cement, 0.5 to 1.5 percent of expanding agent, 60 to 71.5 percent of fly ash, 0 to 0.6 percent of aluminum sulfate, 0 to 0.8 percent of calcium formate, 0 to 1 percent of redispersible latex powder, 0.3 to 0.4 percent of water reducing agent, 0.02 to 0.12 percent of defoaming agent, 0.03 to 0.05 percent of low-viscosity cellulose ether and 0 to 0.1 percent of retarder. According to the invention, the fly ash discharged by a power plant boiler is used as a main material, the alkaline auxiliary material is used for exciting the activity of the fly ash, the Portland cement or sulphoaluminate cement is added, and a plurality of auxiliary agents are added for mixing to form the cement-based self-leveling mortar with high fly ash mixing amount, so that the cement-based self-leveling mortar can directly replace the existing self-leveling mortar and ground manual plastering, the construction speed is high, and the construction cost is low. And the flatness is high.
本发明公开了一种高掺量粉煤灰的水泥基自流平地面找平材料，由以下百分比重量份数的原料组成：普通硅酸盐水泥2.5～27.5％、速溶硅酸钠粉末1.5～2％、轻烧白云石粉2～5％、氧化钙0.5～2.5％、氢氧化钙0.5～1％、硫铝酸盐水泥0～25％、膨胀剂0.5～1.5％、粉煤灰60～71.5％、硫酸铝0～0.6％、甲酸钙0～0.8％、可在分散乳胶粉0～1％、减水剂0.3～0.4％、消泡剂0.02～0.12％、低粘度纤维素醚0.03～0.05％、缓凝剂0～0.1％。本发明将电厂锅炉排放的粉煤灰作为主要材料，以碱性辅料激发粉煤灰活性，加入硅酸盐水泥或硫铝酸盐水泥，辅以多种助剂混合而成的高掺量粉煤灰的水泥基自流平，可以直接代替现有的自流平砂浆与地面人工抹灰，施工速度快，平整度高。
