A kind of anti-ultraviolet radiation concrete and its preparation method

Abstract

The invention discloses an anti-ultraviolet radiation concrete. The components and their parts by weight include: 250-350 parts of cement, 100-150 parts of modified high-titanium heavy slag powder, 10-20 parts of silica fume, gravel 950-1100 parts, high-titanium heavy slag sand 850-1050 parts, admixture 6-12 parts, water-based polyurethane emulsion 2-5 parts, water 155-180 parts. The invention uses modified high-titanium heavy slag and water-based polyurethane emulsion as the main modified raw materials, and can effectively reduce the risk of corrosion of reinforced concrete carbonized steel bars under strong ultraviolet conditions on the basis of ensuring good working performance and mechanical properties; and involves The preparation method is relatively simple, the cost is low, and it is suitable for popularization and application.

Description

A kind of anti-ultraviolet radiation concrete and preparation method thereof technical field The invention belongs to technical field of building materials, be specifically related to a kind of anti-ultraviolet radiation concrete and preparation method thereof. Background technique [0002] In 2018, under the background of the western development, infrastructure construction and the promotion of green economic development on the Qinghai-Tibet Plateau, the entire The planning and construction of the Sichuan-Tibet Railway has been launched, and the infrastructure construction in the high-altitude and strong ultraviolet regions and the urbanization in the Qinghai-Tibet Plateau will be launched soon. City construction and development. Under the condition of strong ultraviolet rays, the carbonization of concrete will deteriorate sharply, and then lead to the protection of the reinforced concrete protective layer. protection failure, etc. In view of the above problems, by i...

AI Technical Summary

Problems solved by technology

[0003] Under the condition of strong ultraviolet rays, the carbonation of concrete will deteriorate sharply, which will lead to the failure of the protective effect of the reinforced concrete protective layer and other problems

In view of the above problems, by increasing the thickness of the concrete protective layer, etc., the stiffness of the concrete will be affected to a certain extent, and the brittleness will be increased, which is not good for the concrete structure; while the conventional concrete surface coating protection process is not only cumbersome in construction, but also greatly increases the engineering cost. cost
