Low-shrinkage foam concrete and preparation method thereof
The invention discloses low-shrinkage foam concrete and a preparation method thereof. The foam concrete is prepared from the following raw materials in parts by mass: 350-450 parts of cement, 50-150 parts of tailing sand, 175-250 parts of water, 6-8 parts of a physical foaming agent, 0.6-1.5 parts of a water reducing agent, 2-5 parts of rubber powder and 2-7 parts of fibers. The preparation method of the foam concrete comprises the following steps: firstly, uniformly mixing and stirring the cement, the tailing sand, the rubber powder and the fibers to obtain a mixture; uniformly mixing water and a water reducing agent, adding the mixture, and uniformly stirring to obtain slurry; adding water to dilute a foaming agent to prepare foaming liquid, and adding the foaming liquid into a foaming machine to prepare foam; and finally, adding the foam into the slurry, mixing and stirring uniformly, pouring into a mold, and curing to the age. According to the low-shrinkage foam concrete and the preparation method thereof, the prepared foam concrete is high in strength and small in shrinkage, the consumption of cement is reduced, and energy is saved.
本发明公开了一种低收缩的泡沫混凝土及其制备方法，该泡沫混凝土由以下质量份数的原材料制成：水泥350～450份、尾矿砂50～150份、水175～250份、物理发泡剂6～8份、减水剂0.6～1.5份、胶粉2～5份、纤维2～7份。泡沫混凝士的制备方法：先将水泥、尾矿砂、胶粉和纤维混合搅拌至均匀得到混合料；将水和减水剂混合均匀后加入混合料搅拌至均匀得到料浆；然后将发泡剂加水稀释制成发泡液，将发泡液加入发泡机制成泡沫；最后将泡沫加入料浆一起混合搅拌至均匀后倒入模具，养护至龄期。本发明提供了一种低收缩的泡沫混凝土及其制备方法，制备的泡沫混凝土强度高、收缩小，而且降低了水泥的用量，节约了能源。
