Foam concrete nano foaming agent and application thereof
The invention discloses a foam concrete nano foaming agent and application thereof, and belongs to the technical field of concrete materials. The foam concrete nano foaming agent is composed of the following components in percentage by mass: 10-50% of cellulose; 10%-50% of a water-soluble polymer material; 5%-30% of a surfactant; and 5%-30% of nanoparticles. The foam concrete nano foaming agent provided by the invention has the advantages of low cost and good foaming effect. Nano foam generated by foaming of the foaming agent is high in stability, and when the foaming agent is applied to preparation of a foam concrete material, the foam concrete is wide in dry density range and low in collapse rate, has good mechanical properties, flowing properties, dry shrinkage properties, stability and heat insulation properties, and is wide in application prospect. The method is suitable for the fields of building materials, housing construction, road and bridge engineering, cast-in-place backfill engineering, pit goaf backfill, garbage burying and the like.
本发明公开了一种泡沫混凝土纳米发泡剂及其应用，属于混凝土材料技术领域。这种泡沫混凝土纳米发泡剂是由以下质量百分比的组分组成：纤维素10％～50％；水溶性高分子材料10％～50％；表面活性剂5％～30％；纳米颗粒5％～30％。本发明提供的泡沫混凝土纳米发泡剂具有成本低、发泡效果好的优点。采用该发泡剂经发泡产生的纳米泡沫稳定性高，将其应用于制备泡沫混凝土材料，泡沫混凝土的干密度范围广，塌陷率低，且具有良好的力学性能、流动性能、干缩性能、稳定性能和隔热性能，应用前景广阔，适用于建材、房建、路桥工程、现浇回填工程、矿坑采空区回填和垃圾掩埋等诸多领域。
