Compression-resistant foam concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses compression-resistant foam concrete and a preparation method thereof. The compression-resistant foam concrete comprises the following components in parts by weight: 80-100 parts of phosphogypsum; 10-20 parts of cement clinker; 40-60 parts of fly ash; 40-60 parts of mineral powder; 10-15 parts of anti-cracking fiber; 60-70 parts of a first water agent; 40-50 parts of a second water agent; 40-50 parts of a third water agent; 3-5 parts of a water reducing agent; 2-7 parts of a foaming agent; the foaming agent is formed by mixing lauryl sodium sulfate, dodecanol, sodium carboxymethyl cellulose and sodium gluconate. The preparation method comprises the following steps: mixing the foaming agent and the first water agent to obtain foam; carrying out ball milling on phosphogypsum, cement clinker and the second water agent to obtain phosphogypsum slurry; adding fly ash, mineral powder, anti-crack fibers and the like into the phosphogypsum slurry, and stirring to obtain foamed cement; and pouring and curing the foamed cement. The pressure-resistant foam concrete prepared by the method has the advantage of high pressure resistance.
本申请涉及混凝土技术领域，具体公开了一种抗压泡沫混凝土及其制备方法。抗压泡沫混凝土包括如下重量份数的组分：磷石膏80‑100份；水泥熟料10‑20份；粉煤灰40‑60份；矿粉40‑60份；抗裂纤维10‑15份第一水剂60‑70份；第二水剂40‑50份；第三水剂40‑50份；减水剂3‑5份；发泡剂2‑7份；发泡剂由十二烷基硫酸钠、十二醇、羧甲基纤维素钠和葡萄糖酸钠混合组成。其制备方法为：将发泡剂和第一水剂混合得泡沫；将磷石膏、水泥熟料和第二水剂球磨得磷石膏浆体；将粉煤灰、矿粉、抗裂纤维等加入磷石膏浆体中搅拌得泡沫水泥；将泡沫水泥浇筑养护。本申请制备的抗压泡沫混凝土具有抗压能力强的优点。
