Abstract

The invention discloses low-cost graphene oxide mortar and a preparation method thereof. The graphene oxide mortar is prepared from the following raw materials in parts by mass: 450 parts of cement, 180 parts of water, 1350 parts of natural river sand, 0.9 part of polycarboxylate superplasticizer, and 16.9 parts of graphene oxide solution raw material. The preparation method of the graphene oxidemortar comprises the steps of proportioning the raw materials, mixing the raw materials, pouring, forming and maintaining, and is simple and easy to operate. By adopting the graphene oxide mortar prepared through the invention, through optimizing the coordinate proportion of the raw materials, and adding the graphene oxide solution raw material, the concrete prepared from the graphene oxide mortarmeets the strength requirement, the price is low, and the price of the graphene oxide mortar prepared through the invention is a half of the price of a like product prepared by other technologies.

Description

technical field

[0001] The invention belongs to the technical field of building materials, in particular to the technical field of preparation methods of cement-based composite materials. Background technique

[0002] Cement-based composite materials, such as cement mortar, are widely used in civil engineering fields such as industrial and civil buildings, bridges, and ports. According to reports, since 2011, the world has produced an average of 3.6 billion cement annually, of which more than 55% comes from China. Cement-based composite materials have high compressive strength, but high brittleness, low tensile strength, poor ductility and toughness, easy cracking and low permeability resistance. Decrease, premature failure or failure of the structure. At the same time, green and sustainable development is an inevitable trend of the times. The extensive use of cement-based composite materials requires the production of a large amount of cement, which seriously affects the ...
