High-performance wet-mixed plastering mortar and preparation process thereof
The invention provides high-performance wet-mixed plastering mortar and a preparation process thereof, and relates to the technical field of building material mortar. The high-performance wet-mixed plastering mortar is prepared from the following raw materials in parts by weight: 240 to 260 parts of cement, 65 to 75 parts of fly ash, 25 to 35 parts of calcium powder, 1285 to 1510 parts of fine aggregate, 250 to 270 parts of high-concentration sewage, 18 to 26 parts of polymer modifier, 3 to 5 parts of plastic retaining agent, 10 to 14 parts of water reducing agent and 1 to 3 parts of thickening time control agent. According to the invention, high-concentration sewage recovered from production of premixed mortar is used as a raw material and is matched with other raw materials for use, and the fine aggregate is composed of fine sand and medium sand, so that the cost of the fine aggregate is lower than that of natural sand, and the bonding strength of the fine aggregate with cement, fly ash and other cementing materials is higher; and through compounding of the fine sand and the medium sand, the problems of poor grading characteristics and grain shape defects of the machine-made sand can be solved.
本发明提供一种高性能湿拌抹灰砂浆及其制备工艺，涉及建筑材料砂浆技术领域。该高性能湿拌抹灰砂浆，以重量份数计，包含以下重量份的原料组成：水泥240～260份、粉煤灰65～75份、钙粉25～35份、细骨料1285～1510份、高浓污水250～270份、聚合物改性剂18～26份、保塑剂3～5份、减水剂10～14份、调凝剂1～3份。本发明中，通过采用预拌砂浆生产回收的高浓污水作为原料，并且配合其他原料进行使用，细骨料采用细砂和中砂组成，使其成本比天然砂低，与水泥、粉煤灰等胶凝材料的粘结强度更高，且通过细砂和中砂的复配能弥补机制砂的级配特征差、粒形缺陷的问题。
