Problems solved by technology

[0003] The existing antifreeze is mainly composed of early-strength components, antifreeze components and air-entraining components, which contain a large amount of methanol, nitrite, chloride salt and ammonia water, etc. Methanol is volatile and toxic, and chlorine salt will It will corrode steel bars and affect the life of the building; ammonia water is a toxic substance with a pungent smell and is volatile. Adding these substances to concrete will seriously affect the quality of life and cause poison to the human body, while nitrite will The alkali content of the concrete increases suddenly, and even alkali return occurs, seriously affecting the quality of the project

Abstract

The present invention discloses a harmless anti-freezing concrete and a preparation method thereof. The harmless anti-freezing concrete is prepared from the following raw materials, by weight: 20-25 parts of cement, 20-45 parts of rubber particles, 10-20 parts of water, 10-20 parts of fine stone, 1-2 parts of polymer fibers, 4-6 parts of anhydrite, and 15-20 parts of an anti-freezing agent. With the scheme, no harm on buildings and human body can be generated, and the anti-freezing index achieves the daily used industry standard.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a harmless antifreeze concrete and a preparation method thereof. Background technique [0002] During construction, various harsh weather conditions are often encountered, especially in winter, when long-term low temperature has a great impact on the mixing of concrete. How to prevent concrete from freezing at low temperature has always been a headache for engineers . [0003] The existing antifreeze is mainly composed of early-strength components, antifreeze components and air-entraining components, which contain a large amount of methanol, nitrite, chloride salt and ammonia water, etc. Methanol is volatile and toxic, and chlorine salt will It will corrode steel bars and affect the life of the building; ammonia water is a toxic substance with a pungent smell and is volatile. Adding these substances to concrete will seriously affect the quality of life and cause poiso...
