High-strength antifreezing cement and preparation method thereof

Abstract

The invention provides high-strength antifreezing cement and a preparation method thereof. The cement is prepared from the following ingredients including Portland cement clinker, gypsum, diatomite, attapulgite, fly ash, glass waste slag, furnace slag, calcium chloride, cement modifying agents, regulating agents and stabilizing agents. The preparation method comprises the following steps that the cement modifying agents and water are mixed to obtain mixed liquid; then, the mixed liquid is added into a mixture of the rest ingredients; mixing and stirring are performed to obtain the high-strength antifreezing cement. The cement has higher strength and better antifreezing performance; the phenomena of detritus falling, falling and cracking of the cement generated in the application process in winter can be effectively avoided; the use performance of the cement is greatly improved; better application values are realized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength antifreeze cement and a preparation method thereof. Background technique [0002] Cement is a building material with a wide range of applications. The existing cement products are not strong enough to meet some special requirements. The current cement production process is complicated and the cost is low. Cement, powdery hydraulic inorganic gelling material, can be mixed with water to form 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 an important It is widely used in civil construction, water conservancy, national defense and other projects. There are many types of cement, which can be divided into three categories: general cement, special cement and special cement according to its use and performance. However, whether it is general-purpose cement, special-p...

AI Technical Summary

Problems solved by technology

However, whether it is general cement, special cement or special cement on the market, the problem of coal consumption and material consumption is very serious, which also increases the manufacturing cost of the enterprise to a certain extent.

[0003] The construction industry is generally constructed outdoors. In winter, when the outdoor temperature is below zero, the cement will freeze, so construction will not be possible.

Usually, in order to prevent the cement concrete mixture from being damaged by freezing at low temperature, people usually use antifreeze methods such as adding antifreeze or steam curing, heat preservation, etc., but the latter is not suitable for large-scale application due to complicated construction and low efficiency.
