Graphene modified concrete material and preparation method thereof
The invention relates to a graphene modified concrete material and a preparation method thereof, the graphene modified concrete material comprises the following components by weight: 100 parts of cement, 132-224 parts of coarse aggregate, 258-386 parts of fine aggregate, 23-46 parts of fly ash, 6-12 parts of modified graphene oxide, 1.8-3.6 parts of a water reducer, 5-10 parts of polypropylene fiber and 65-85 parts of water. Compared with the traditional method that graphene or graphene oxide is directly added into a cement-based composite material, the concrete material added with the modified graphene oxide is prepared, and the added modified graphene oxide is a product obtained through surface modification treatment; the concrete material prepared by the method disclosed by the invention has the advantages of higher strength and toughness and difficulty in cracking.
本发明涉及一种石墨烯改性混凝土材料及其制备方法，按照重量份数计算，包括以下成分：100份水泥、132‑224份粗骨料、258‑386份细骨料、23‑46份粉煤灰、6‑12份改性氧化石墨烯、1.8‑3.6份减水剂、5‑10份聚丙烯纤维和65‑85份水。本发明制备了一种添加有改性氧化石墨烯的混凝土材料，相比较于传统将石墨烯或氧化石墨烯直接添加到水泥基复合材料中，本发明加入的改性氧化石墨烯是经过表面改性处理得到的产物，使用本发明的方法制备的混凝土材料具有更高的强度和韧性，并且不易开裂的优点。
