Construction process of retarded concrete wall body

Abstract

The invention provides a construction process of a retarded concrete wall body. The construction process comprises the steps of defining a construction area on the ground, preparing ardealite powder,preparing a wall body framework, preparing a plurality of wall body formworks, hoisting the wall body formworks, preparing retarded concrete, removing all impurities in the wall body framework and thewall body formworks, pouring cement mortar, pouring the retarded concrete into the wall body framework in multiple times, vibrating the retarded concrete, maintaining the retarded concrete wall bodyand dismantling a protective material. According to the technical scheme, ardealite is adopted to replace natural gypsum to prepare the retarded concrete, the concrete setting speed is decreased, theconcrete setting strength is improved through sufficient vibration, and in addition, a large number of through-wall screws are adopted, so that the structural strength of an existing wall body formwork supporting system is greatly enhanced, the flatness of the two sides of a poured wall body is effectively guaranteed, and the construction process has the advantages that the wall body formworks areconvenient to install, the poured wall body is good in quality and low in cost, raw materials are saved, construction time is shortened, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a construction technique for retarded concrete walls. Background technique [0002] In recent years, with the development of construction technology and the strong support of national policies, various new building materials and building structural components have been widely put into mass production and application, which has won praise from the society and achieved good economic value. In the construction of building walls, the wall structure made of steel bars and concrete is generally used, which has the advantages of fast construction speed, high efficiency, and good wall structure strength. However, when the concrete setting time is too fast, it is easy to use The inclusion of air or other impurities in the concrete will affect the setting strength of the concrete. In order to reduce the setting speed of the concrete, an appropriate amount of re...

Problems solved by technology

In the construction of building walls, the wall structure made of steel bars and concrete is generally used, which has the advantages of fast construction speed, high efficiency, and good wall structure strength. However, when the concrete setting time is too fast, it is easy to use The inclusion of air or other impurities in the concrete will affect the setting strength of the concrete. In order to reduce the setting speed of the concrete, an appropriate amount of retarder is generally added in the concrete mixing process. In the prior art, most of the natural gypsum is used as the production material of the retarder. The composition of natural gypsum is relatively simple. However, the mining capacity of natural gypsum in nature is very limited at present, which cannot meet the development needs of the construction industry.
