Multifunctional foamed concrete and preparation method thereof
The invention discloses multifunctional foamed concrete. The concrete comprises the following raw materials in parts by weight: 50-60 parts of cement, 20-30 parts of silica fume, 20-30 parts of fly ash, 10-20 parts of superfine slag powder, 20-30 parts of antirust steel fibers, 15-20 parts of water, 4-6 parts of a polycarboxylate superplasticizer, 140-150 parts of desert sand, 38-40 parts of steelfibers and 5-15 parts of a foaming agent. The desert sand is used for partially or completely replacing river sand, so that the mechanical property of the concrete can be improved, the contradictionbetween supply and demand of building sand is effectively relieved, abundant resources of the desert sand in the northwest region are fully utilized, and the principles of adapting to local conditions, using local materials and reasonably developing and utilizing natural resources are followed; the foamed concrete has the advantages of good sound insulation and heat insulation effects, uniform texture and difficulty in cracking; and the steel fibers are used, so that the concrete has very high compressive strength, the bending strength is improved, the building performance requirement is met,and the concrete can be widely popularized and used.
本发明公开了一种多功能发泡混凝土，由以下重量份原料组成：水泥50‑60份、硅灰20‑30份、粉煤灰20‑30份、矿渣微粉10‑20份、防锈钢纤维20‑30份、水15‑20份、聚羧酸减水剂4‑6份、沙漠砂140‑150份、钢纤维38‑40份、发泡剂5‑15份；本发明使用沙漠砂部分或完全替代河砂，能够提高混凝土的力学性能，有效缓解建筑用砂的供需矛盾，充分利用了西北地区沙漠砂的丰富资源，遵循因地制宜、就地取材和合理开发利用自然资源的原则；泡沫混凝土具有隔音隔热效果好，质地均匀，不易开裂的优点；使用钢纤维使得混凝土具有很高的抗压强度，且提升了弯曲强度，满足建筑性能要求，能够广泛推广使用。
