Yellow river sand dry-mixed mortar for sculpture and preparation process thereof
The invention relates to the technical field of building materials, in particular to Yellow River sand dry-mixed mortar for sculptures and a preparation process of the Yellow River sand dry-mixed mortar. The invention relates to a preparation process of Yellow River sand dry-mixed mortar for sculpture. The preparation process comprises the following steps: pretreatment and superfine processing of Yellow River sand; carrying out hydroxylation, coupling and grafting reaction treatment on the fly ash; carrying out surface modification on the steel slag powder and the basalt fiber; preparing a dihydrate gypsum retarder by using the desulfurized gypsum; and preparing the sculpture dry-mixed mortar. The modified steel slag powder and the basalt fiber are adopted as admixtures of the mortar, the strength and durability of the mortar can be improved, the copolymer emulsion is used for modifying the surface of the steel slag powder, the water absorption of the steel slag powder is reduced, cement setting can be delayed, cracking caused by expansion is avoided, adsorbed water is slowly released in the later stage of hydration of a glue material, and the water absorption performance of the mortar is improved. And the steel slag powder improves the compactness of the mortar and increases the thickness of a coating surface, and the basalt fibers with high ultimate expansion and contraction rate and tensile modulus can inhibit the development of micro-cracks.
本发明涉及建筑材料技术领域，具体涉及一种用于雕塑的黄河砂干粉砂浆及其制备工艺。一种用于雕塑的黄河砂干粉砂浆的制备工艺，包括以下步骤：黄河砂的预处理和超细加工；对粉煤灰羟基化、偶联和接枝反应处理；钢渣粉和玄武岩纤维的表面改性；用脱硫石膏制备二水石膏缓凝剂；雕塑干粉砂浆的配置。本发明采用改性钢渣粉和玄武岩纤维作为砂浆的掺合料，能够提高砂浆的强度和耐久性能，用共聚物乳液对钢渣粉表面改性，降低钢渣粉的吸水性，使其能延缓水泥凝结而又不因膨胀开裂，在胶材水化后期缓慢释放所吸附的水，促进胶材水化反应，钢渣粉提高砂浆的密实度，提高涂抹面的厚度，玄武岩纤维较高的极限伸缩率和拉伸模量可抑制微裂缝的发展。
