Problems solved by technology

[0003] However, the existing ordinary cement has low solidification strength and poor structural stability. It is easy to cause gaps and cracks after long-term weathering or impact, which will lead to water seepage inside the cement structure, causing major safety problems such as holes and structural collapse.
With the development of material science and construction engineering, under the influence of social demand, special cement products have been listed, but the improvement in cement performance is still not obvious

Abstract

The invention discloses environment-friendly compound enhanced type cement and a preparation method thereof and relates to the technical field of building materials. The cement is prepared from the following raw materials: volcanic mud of Wudalianchi of Heilongjiang, activated slag powder, borax, bentonite, modified sepiolite powder, carboxymethylcellulose ether, basalt fibers, sodium silicate, building latex liquid, an expanding agent and an early strength agent. According to the preparation method of the environment-friendly compound enhanced type cement, the raw materials are mixed and ground to prepare the cement. The preparation method of the cement provided by the invention is simple and convenient; the cement has the characteristics of good strength, structure stability, anti-seepage and waterproof performance, anti-freezing and heat-resisting performance, corrosion and weathering resisting performance and the like and has a wide application field and a long service life.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly composite reinforced cement and a preparation method thereof. Background technique [0002] Cement, 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. Cement is especially suitable for making concrete, precast concrete, fair-faced concrete, GRC products, adhesives and other special occasions. It is widely used in colored pavement bricks, permeable bricks, cultural stones, sculpture crafts, terrazzo, wear-resistant floors, putty, etc., with High light reflection performance makes the manufactured curbstones, road signs, and road central dividers have higher traffic safety performance. [0003] However, the existing ordinary cement has low solidification strength and poor str...
