Multifunctional cement-based thick-layer self-leveling material, composite ground and construction method of composite ground
The invention discloses a multifunctional cement-based thick-layer self-leveling material, a composite floor and a construction method of the composite floor, and relates to the field of building materials. The multifunctional cement-based thick-layer self-leveling material comprises the following components in parts by mass: 18-22.5 parts of cement, 1.5-2.5 parts of beta-semi-hydrated gypsum, 0.4-0.8 part of ash calcium, 8-10 parts of heavy calcium carbonate, 51-84 parts of quartz sand, 0.01-0.03 part of a plastic expanding agent, 0.12-0.15 part of a water reducing agent, 0.02-0.04 part of hydroxypropyl methyl cellulose ether, and 0.5 to 1 part of redispersible latex powder. The multifunctional cement-based thick-layer self-leveling material disclosed by the invention is low in material cost, high in construction thickness, high in fluidity, strong in binding power and relatively high in early-stage and later-stage strength. The flatness of the thick-layer self-leveling material is high, the high-precision requirement that the fall within a 2-meter guiding rule is smaller than 2 mm can be met only through one-time construction, the thick-layer self-leveling material can be directly and fixedly connected with a plate layer, a binding agent does not need to be added during the process, the construction procedures are reduced, and the construction efficiency is improved.
多功能水泥基厚层自流平材料和复合地面及其施工方法，涉及建筑材料领域，包括如下质量份计的组分：水泥18‑22.5份，β‑半水石膏1.5‑2.5份，灰钙0.4‑0.8份，重钙8‑10份，石英砂51‑84份，塑性膨胀剂0.01‑0.03份，减水剂0.12‑0.15份，羟丙基甲基纤维素醚0.02‑0.04份，可再分散乳胶粉0.5‑1份。本发明的一种多功能水泥基厚层自流平材料，材料的成本低，施工厚度高，流动性高，粘结力强，早期及后期强度较高。厚层自流平的平整度高，只需一次施工就能达到2米靠尺内落差低于2mm的高精度要求，厚层自流平可直接与板层固定连接，中间不需要添加粘结剂，减少施工工序，提高施工效率。
