Graphene oxide thin-layer dry-mixed mortar for accurate building blocks and process thereof

Abstract

The invention discloses graphene oxide thin-layer dry-mixed mortar for accurate building blocks and a process thereof. The process is characterized in that graded medium and fine sand produced by drying and screening 42.5 / 32.5-grade general Portland cement and wet quartz sand and graphene oxide powder are used as raw materials, metered and proportioned by a computer, and uniformly stirred and mixed to prepare the graphene oxide thin-layer dry-mixed mortar, which is used for gap masonry and surface plastering of accurate building blocks. The mortar for masonry is prepared from following components in percentage by weight: 30% of 42.5-grade general silicate, 50% of medium sand, 19.97% of fine sand and 0.03% of graphene oxide powder; and is prepared through uniform stirring and mixing. The mortar for plastering is prepared from following components in percentage by weight: 30% of 32.5-grade general Portland cement, 50% of fine sand, 19.97% of medium sand and 0.03% of graphene oxide powder, and is prepared through uniform stirring and mixing.

Description

technical field [0001] This patent relates to the technical field of building materials, in particular to a graphene oxide thin-layer dry-mixed mortar for precise building blocks and its construction method. Background technique [0002] With the progress and development of our society, people's demand for housing construction has evolved from simple living demands to functional requirements such as energy saving and emission reduction, green environmental protection, and environmental comfort. Therefore, the "three new" technological products and construction techniques in the construction industry emerge in an endless stream. As far as the wall construction technology is concerned, it has also developed from the traditional ordinary block masonry structure to the precise block masonry structure. Using this new technology to build the wall, the wall surface is smooth and tidy, and the thin-layer dry-mixed mortar is directly used for masonry and plastering, which saves a lo...

Problems solved by technology

However, in order to meet the performance requirements, the existing thin-layer dry-mixed mortars developed and supplied all use a variety of organic polymers as admixtures, which not only contain harmful components that pollute the environment and damage health, but also have many types and combinations of admixtures. In order to reduce costs, many companies choose cheap polymers instead, which not only reduces the strength, but also seriously exceeds the standard of formaldehyde, benzene and other harmful substances, and there is a phenomenon of uneven product quality. Many negative impacts on the industry
