Concrete stirring method convenient for building construction

Abstract

The invention relates to the technical field of building construction, and discloses a method for preparing a concrete mixer, which comprises the following steps of: 1, selecting a mixer according to construction requirements, selecting a direct-falling mixer and a forced mixer according to different stacking densities, mixing time and mixing frequency, and selecting one of the two mixers; 2, after a proper stirrer is selected, preparation before construction is carried out; 3, carrying out pre-stirring; 4, officially stirring; 5, pouring out the stirred concrete, and then carrying away the concrete.According to the concrete stirring method convenient for building construction, the materials are added into the stirring machine to be stirred, cement, sand and water are put into a half barrel to be stirred firstly, then pebbles are added, stirring is conducted again, and due to the fact that pre-stirred cement mortar or cement neat paste has an activation effect on cement, the stirring speed is increased; therefore, the stirring quality is obviously higher than that of an existing stirring mode, if the cement consumption is not changed, the concrete strength can be improved by about 15%, or under the condition that the concrete strength is the same, the cement consumption can be reduced by about 15%-20%.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a concrete mixing method convenient for building construction. Background technique [0002] Concrete mixing is an operation method of mixing cement, lime, water and other materials and mixing them evenly. There are two types of concrete mixing: manual mixing and mechanical water mixing. Concrete batching plants are widely used in my country's industry, agriculture, transportation, national defense, water conservancy, municipal and other construction projects, and the demand is increasing. [0003] Although the domestic concrete mixing equipment continues to innovate and progress on the basis of learning from foreign products, and the technical level is gradually improved, the existing concrete mixing method cannot give the mortar activation effect when mixing concrete, which leads to insufficient strength. For this reason, we propose a A concrete mixing method co...

[0003] Although the domestic concrete mixing equipment is constantly innovating and improving on the basis of foreign products, the technical level is gradually improved. The existing concrete mixing method cannot activate the mortar when mixing concrete, which leads to insufficient strength. For this reason, we propose A kind of concrete mixing method convenient for building construction
