Abstract

The invention discloses graphene-modified concrete and belongs to the field of concrete. The graphene-modified concrete is prepared from the following components in parts by weight: 5-20 parts of cement, 25-40 parts of coarse sand, 35-48 parts of stones, 10 parts of water, 0.05-0.15 parts of graphene and 5-15 parts of a water reducing agent. The graphene-modified concrete has the characteristics of being simple in preparation technology, low in cost and short in complete coagulation time. Compared with common concrete, the graphene-modified concrete is capable of resisting higher external force, the complete coagulation time can be shortened into 10d from 28d required for complete coagulation of the common concrete, and the dosage can be reduced by 25%.

Description

technical field [0001] The invention relates to the field of concrete, and more specifically, to a graphene-modified concrete and a manufacturing method thereof. Background technique [0002] Graphene is a two-dimensional crystal exfoliated from multilayer graphite, which has excellent properties such as high strength, high transparency, good flexibility, and good electrical and thermal conductivity. Concrete is an essential building material where we live, work, play and more. We add graphene to concrete. On the one hand, the existing concrete is mainly composed of cement, stone, sand and water. The amount of cement is relatively large. It is made in a certain process, which makes the concrete process relatively complicated and the cost is high. [0003] Chinese patent document CN106167384A discloses a kind of concrete, which is obtained by mixing cement, sand, stones, water, water reducer, phenolic fiber and montmorillonite; wherein, relative to 1000kg of stones, the amo...
