Autoclaved aerated concrete slab collocated with rust resistant layer steel bar and concrete mortar

Abstract

The invention relates to an autoclaved aerated concrete slab provided with cement mortar reinforced bars having rust prevention layers and an application thereof. The prior precast slabs have large specific gravity, resulting in high weight of buildings and very high cost of foundations. The autoclaved aerated concrete has low specific gravity but poor strength, so as not to be used as supporting parts. The inventive product comprises building used concrete structural slabs, wherein the concrete is autoclaved aerated concrete (1), and the concrete in the structural slabs is provided with tension resistant strengthening ribs (3) containing carbon fibers (2). The product can be used as precast elements for buildings, such as floor slabs, roof slabs and wall slabs, etc.

Description

Autoclaved aerated concrete slab equipped with cement mortar antirust layer reinforcement Technical field: The invention relates to a building prefabricated board with antirust layer steel bars made of autoclaved aerated light concrete and its application as floor and roof boards. Background technique: The proportion of existing prefabricated panels is relatively large, resulting in a relatively large building weight and high foundation costs. The specific gravity of air-entrained concrete is relatively small, but its strength is not good enough to be used as a load-bearing component. And for many years, people have been accustomed to using steel bars as tensile components. Since one of the main raw materials of air-entrained concrete is lime, steel bars are buried in air-entrained concrete, which will soon be corroded and brittle. Air concrete has always been available only as a non-load-bearing component. Invention content: The purpose of the present invention is to...
