Cement-based sand-free self-leveling terrace material prepared from waste powder and preparation process of cement-based sand-free self-leveling terrace material
The invention belongs to the field of building materials, and particularly discloses a cement-based sand-free self-leveling floor material prepared from waste powder and a preparation process thereof.The cement-based sand-free self-leveling floor material comprises main materials and auxiliary materials, the main materials comprise cement and powder, the total weight part of the main materials is 1000, and the auxiliary materials comprise, by weight, 0-50 parts of fly ash, 0-30 parts of fly ash, 0-30 parts of fly ash, 0-30 parts of fly ash, 0-30 parts of fly ash, 0-30 parts of fly ash, 0-30 parts of fly ash and 0-30 parts of fly ash. 0.1 to 0.2 part of cellulose ether, 0.1 to 0.3 part of expanding agent, 0.5 to 2 parts of modified polyvinyl alcohol fiber and 2.5 to 3.25 parts of water reducing agent; and 180 to 210 parts of water. The sand-free self-leveling floor material is prepared by replacing all fine aggregates in self-leveling mortar with the powder, so that the physical and mechanical properties of the floor material meet or exceed the requirements of the industrial standard Cement-based Self-leveling Mortar for Ground (JCT985-2017), a large amount of powder can be consumed, and the segregation of the self-leveling floor mortar can be reduced.
本发明属于建筑材料领域，具体公开了一种利用废弃粉料制备的水泥基无砂自流平地坪材料及其制备工艺，所述水泥基无砂自流平地坪材料，包括主料和辅料，所述主料为水泥和粉料，合计重量份为1000份，并含有以下重量份的辅料：粉煤灰0~50份，纤维素醚0.1~0.2份，膨胀剂0.1~0.3份，改性聚乙烯醇纤维0.5~2份，减水剂2.5~3.25份；以及水180~210份。本发明利用粉料取代自流平砂浆中的全部细骨料，制备无砂自流平地坪材料，使该地坪材料的物理力学性能满足或超过行业标准《地面用水泥基自流平砂浆》（JCT985‑2017）的要求，既可以大量消纳粉料，又可以减少自流平地坪砂浆的离析。
