Lightweight thermal-insulation high-strength concrete and preparation method thereof
The invention discloses lightweight thermal-insulation high-strength concrete and a preparation method thereof. The concrete is prepared from the following components in parts by mass: 270 to 300 parts of cement, 130 to 220 parts of ceramsite composite microspheres, 85 to 110 parts of fly ash, 360 to 480 parts of coal cinder ash, 5.5 to 7 parts of a water reducing agent, 0.7 to 0.9 part of glass fibers, 110 to 160 parts of water, 0.7 to 1.2 parts of carbon nanotubes grafted carbon fibers and 5 to 9 parts of a foaming agent. The preparation method comprises the following steps: firstly, crushing the large ceramsite for later use, and then preparing materials, feeding, pouring, vibrating, demolding and curing. The concrete is low in cost, energy-saving and environment-friendly, and still has relatively high mechanical properties and durability.
本发明公开了一种轻质保温高强度混凝土及其制备方法，该混凝土按质量份数包括以下组分：水泥270‑300份，陶粒复合微球130‑220份，粉煤灰85‑110份，煤渣灰360‑480份，减水剂5.5‑7份，玻璃纤维0.7‑0.9份，水110‑160份，接枝碳纳米管的碳纤维0.7‑1.2份，发泡剂5％‑9％。制备方法包括如下步骤：首先将大陶粒破碎后备用，然后经配料、投料、浇筑并振捣、拆模及养护制得。本发明在具备低成本、节能环保的同时依然具备较强的力学性能和耐久性能。
