Anti-freezing gelled sand gravel composite material
The invention belongs to the technical field of building materials, and particularly relates to an anti-freezing gelled sand gravel composite material. The composite material is prepared from, by weight, 60 to 100 parts of cement, 10 to 30 parts of fly ash, 100 to 120 parts of water, 600 to 650 parts of sand, 850 to 900 parts of pebbles of 20 to 40mm, 550 to 600 parts of pebbles of 5 to 20mm and an additive, wherein the additive accounts for 1 to 3.4 percent of the total amount of the raw materials. The composite material prepared by adopting the formula disclosed by the invention not only can be used for on-site construction, but also has excellent pressure resistance and anti-freezing durability.
本发明属于建筑材料技术领域，具体涉及一种抗冻型胶凝砂砾石复合材料。该复合材料包括以下重量份的原料：水泥60‑100份、粉煤灰10‑30份、水100‑120份、砂600‑650份、20‑40mm卵石850‑900份、5‑20mm小卵石550‑600份和外加剂，其中外加剂占原料总量的1‑3.4%。采用本发明配方制备的复合材料不仅能够用于现场施工，而且具备优良的抗压性和抗冻耐久性。
