Wall surface structure

Abstract

The invention discloses a wall surface structure and belongs to the field of concrete. A wall surface structure can repair small-sized cracks which are not positioned in a bearing wall, after repairing is completed, the concrete for repairing and the original wall can form a relatively firm connection, the repaired and filled concrete is not easily separated from the original wall under the actionof external force, cracks unlikely to reappear, bearing and compression resistance can be realized together with the original wall, the performance of the original wall with cracks is greatly enhanced, meanwhile, workers can repair the cracks conveniently, the phenomenon that concrete overflows in the repairing process is avoided, waste of the concrete is not likely to be caused, the workers do not need to monitor the cracks in real time in the process that cement slurry for repairing is injected into the cracks, the work content of the workers is greatly simplified, and the work intensity ofcrack repairing is reduced.

Description

technical field [0001] The invention relates to the field of concrete, and more specifically relates to a wall structure. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. , Ordinary cement concrete is the most common inorganic cementitious material. [0003] Micro-expansion concrete refers to the addition of a certain expansion agent to ordinary concrete, so that the concrete can expand to a certain extent during the hydration period by relying on the action of the expansion agent, thereby making up for the shrinkage of the concrete, preventing concrete cracks, and improving concrete performance. Purpose. [0004] With the rapid development of the construction industry, architects pay more attention to the deformation of expan...

AI Technical Summary

Problems solved by technology

[0005] In today's society, cement concrete is a common building material. However, in some newly-built housing or commercial buildings, there will be cracks on the walls before they are put into use, which greatly affects the safety of housing or commercial buildings. Because the volume of cement concrete will shrink slightly during the curing process, if only cement concrete is injected into the cracks, the volume will shrink during the curing process of the concrete, and the concrete filled in the cracks will not be able to perform load-bearing functions well, that is It is difficult for the filled concrete to cooperate with the damaged wall to complete load-bearing or compressive work, and the threat of cracks still exists
