Novel foam light soil and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to novel foam light soil and a preparation method thereof. The foam light soil is composed of cementing material slurry and foam. The bubble rate of the foam light soil is 60-70%; the cementing material slurry is formed by mixing a gel solid raw material and water according to a water-solid ratio of 1: 1.80-1: 1.85, and the gel solid raw material comprises the following raw materials in percentage by mass: 10%-15% of fly ash, 65%-78% of cement and 12%-20% of superfine limestone powder; the foam is prepared by mixing a foaming agent and a foam stabilizer through air compression, and the foam stabilizer comprises maltodextrin and cocamidopropyl betaine. The foam light soil has excellent light weight and mechanical properties, and the limestone powder can improve the early strength of the foam light soil, so that the construction efficiency in winter can be improved.
本发明属于建筑材料技术领域，具体涉及一种新型泡沫轻质土及其制备方法。所述泡沫轻质土由胶凝材料料浆和泡沫组成；所述泡沫轻质土气泡率为60‑70％；所述胶凝材料料浆由凝胶固体原料和水按照水固比为1:1.80‑1:1.85混合而成，所述凝胶固体原料中各原料及其质量百分含量为：粉煤灰10％‑15％，水泥65％‑78％，超细石灰石粉12％‑20％；所述泡沫有发泡剂和稳泡剂混合通过空气压缩制成，所述稳泡剂包括麦芽糊精和椰油酰胺基丙基甜菜碱。所述泡沫轻质土兼具了优良的轻质性和力学性能，石灰石粉可提高泡沫轻质土早期强度，有利于提高冬季施工效率。
