A self-decorating active powder concrete and its application hanging board and application method

Abstract

Provided are self-decoration reactive powder concrete and an application hanging plate and application method thereof. The self-decoration reactive powder concrete is prepared from 16%-30% of cement, 10%-35% of admixture, 1%-5% of fibers, 23%-44% of fine aggregates, 0.5%-5% of high-efficiency water reducing agent, 0-0.5% of colorant, 0-5% of titanium dioxide and 9%-18% of water, the self-decoration reactive powder concrete serves as a construction material and a decorative material, the compressive strength is larger than or equal to 100 Mpa, the flexural strength is larger than or equal to 15 Mpa, the fluidity ranges from 300 mm to 350 mm, pouring is conducted to make a decorative hollow-out hanging plate through a hollow-out mold, reinforcements are not needed, and a light and attractive hanging plate can be made. Compared with an ordinary decorative hollow-out hanging plate, the hanging plate is free of reinforcements, small in thickness, light in size, light in weight, convenient to transport and install, rapid and efficient in construction, high in strength, good in bearing capacity, resistant to impact, good in waterproof and anti-cracking property, good in weather resistance, good in decorative effect and capable of being widely applied to fabricated building construction.

Description

technical field [0001] The invention relates to the technical field of decorative hollow hanging boards, in particular to a self-decorating active powder concrete and its application hanging board and application method. Background technique [0002] In the design and construction of architectural decoration projects, in order to make the surface of the building beautiful, it is generally necessary to install decorative surfaces on the surface, such as painting decorative paints, laying decorative panels, etc. These decorative surfaces not only consume a lot of man-hours and materials, but also make the The cost of the project is greatly increased, and with the extension of the service life, fading, peeling, and peeling often occur, which seriously affects the appearance of the building. Ordinary reinforced concrete hollow hanging panels are thick, bulky and self-heavy. At the same time, because ordinary concrete is prone to efflorescence and cause color difference, it gener...
