Pumping type impact sound insulation cement-based self-leveling mortar
The invention relates to pumping type impact sound insulation cement-based self-leveling mortar which comprises the following components in percentage by mass: 17%-26% of ordinary cement, 15%-30% of special cement, 5%-15% of a flexible sound insulation material, 2%-5% of silica fume, 2%-5% of gypsum, 0.5%-1.0% of redispersible latex powder, 0.05%-0.1% of cellulose ether, 0.05%-0.1% of tartaric acid, 0.03%-0.05% of a defoaming agent, 0.005%-0.01% of an air entraining agent, 0.01%-0.03% of a coagulation accelerator, 0.3%-0.5% of a pumping agent and the balance of sand; and the ordinary cement is ordinary Portland cement, and the special cement is high-alumina cement or sulfur-aluminum cement. The material has the characteristics of pumpability, high flowability, high hardening speed, high early strength, high tensile adhesive strength, high wear resistance, small volume change rate and difficulty in cracking, has an impact sound insulation effect, can optimize a ground structure, is convenient to construct and short in construction period, can optimize the ground structure and is suitable for large-area construction building floors with high flatness requirements and sound insulation requirements.
本发明涉及一种泵送型撞击声隔声水泥基自流平砂浆，包括以下组分，按质量百分比计为：普通水泥17％～26％，特种水泥15％～‑30％，柔性隔音材料5％～15％，硅灰2％～5％，石膏2％～5％，可再分散乳胶粉0.5％～1.0％，纤维素醚0.05％～0.1％，酒石酸0.05％～0.1％，消泡剂0.03％～0.05％，引气剂0.005～0.01％，促凝剂0.01％～0.03％，泵送剂0.3％～0.5％，余量为砂；所述普通水泥为普通硅酸盐水泥，所述特种水泥为高铝水泥或硫铝水泥。本发明具有可泵送、高流动性、硬化速度快、早期强度高、拉伸粘结强度大、耐磨性高、体积变化率小、不易开裂的特点，且具有撞击声隔声的作用，本发明可以优化地面结构、施工便捷、工期短，适用于对平整度要求较高和有隔音需求的大面积施工楼地面。
