Problems solved by technology

[0004] At present, in the production process of cement on the market, the problem of coal consumption and material consumption is serious, and the production process is complicated, which not only causes waste of resources, but also causes environmental pollution and increases the manufacturing cost of enterprises.
And the cement strength, grinding effect, hydration efficiency and workability of these cements need to be improved

Abstract

The invention discloses environment-friendly building cement. The environment-friendly building cement is prepared from, by weight, 55-65 parts of cement clinker, 5-10 parts of modified hair fibers, 3-8 parts of nano boron fibers, 10-15 parts of olivine powder, 1-5 parts of rare earth slag and 1-5 parts of function additive; the function additive is prepared by conducting a solution copolymerization reaction between vinylboronic acid pinacol cyclic ester, dimethyl vinylphosphonate, methyl acrylate and trans-zeatin glucoside. The environment-friendly building cement is stable in performance andhigh in bonding power and cement strength, and has better compressive performance like the hydration efficiency, grinding assistance effect and workability than traditional cement.

Description

technical field [0001] The invention relates to the technical field of concrete admixtures, in particular to a concrete additive and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of society, various high-rise buildings, bridges and tunnels have sprung up like mushrooms, and the use of cement as a building material is indispensable behind these large-scale construction projects. Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. It is one of the three basic materials of the construction industry, with a large amount of use and a wide range of applications, and is known as "the food of the construction industry". Due to its relatively excellent performance and low production cost, it is widely used in the fields of urban infras...
