Graphene oxide-metakaolin modified foam concrete and preparation method thereof
The invention belongs to the field of environment-friendly building materials, and particularly relates to graphene oxide-metakaolin modified foam concrete which is prepared from the following raw materials in parts by mass: 480-520 parts of cement, 50-60 parts of metakaolin, 0.2-0.8 part of graphene oxide, 1-3 parts of a water reducing agent, 2-6 parts of a foaming agent and 250-300 parts of water. The foam concrete is modified by graphene oxide-metakaolin, the compressive strength of the foam concrete is greatly improved, the foam concrete has excellent dry density and heat conductivity coefficient under the synergistic effect of GO and MK, and the heat conductivity coefficient is less than 0.19 W/(m.K); the foam concrete achieves the effects of light weight, high strength and low heat conductivity.
本发明属于环保建筑材料领域，具体涉及一种氧化石墨烯‑偏高岭土改性泡沫混凝土，所述混凝土由以下质量份原料制备而成：480‑520份水泥，50‑60份偏高岭土，0.2‑0.8份氧化石墨烯，1‑3份减水剂，2‑6份发泡剂，250‑300份水，所述泡沫混凝土经过氧化石墨烯‑偏高岭土的改性，大幅提高泡沫混凝土的抗压强度，GO和MK的协同作用可以使得泡沫混凝土具有优良的干密度和导热系数的表现，导热系数则达到了小于0.19W/(m·K)；使得泡沫混凝土达到了质轻、高强和低导热的效果。
