Preparation process of high-strength double-permeation curing type concrete

Abstract

The invention discloses a preparation process of high-strength double-permeation curing type concrete and belongs to the technical field of concrete preparation. According to the preparation process of the high-strength double-permeation curing type concrete, double-permeation balls are added in the stirring process, thus on one hand, added excessive water can be recycled and stored, in the high-temperature steam curing process, water in the double-permeation balls forms steam to overflow, evaporation curing from inside to outside is achieved, in cooperation with curing from outside to insidein the prior art, a two-way curing effect can be achieved, the evaporation curing efficiency can be remarkably improved, the situation that the internal curing effect of the concrete is lower than theexternal curing effect can be effectively avoided, the curing uniformity is improved, and the quality of an obtained concrete finished product is better. Meanwhile, in the water absorption process ofthe double-permeation balls, reinforcing balls can be released and uniformly mixed into slurry, so that the setting force of the concrete finished product is effectively improved, and the structuralstrength is improved.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, and more specifically relates to a preparation process of high-strength double-osmosis curing concrete. Background technique [0002] 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 appropriate proportions, uniformly stirred, compacted and cured. In concrete, sand and stone act as the skeleton, which is called aggregate; cement and water form cement slurry, which wraps on the surface of the aggregate and fills its voids. Before hardening, the cement slurry acts as a lubricant, giving the mixture a certain degree of workability and facilitating construction. After the grout has hardened, it binds the aggregates into a solid whole. Generalized concrete is an artificial stone made of cementitious materials, coarse and fine aggregates, water and ...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a high-strength double-osmotic curing concrete preparation process, which adds double-osmotic balls during the mixing process, on the one hand, it can recover the added excess water and store it , in the process of high-temperature steam curing, the water in the double seepage ball forms water vapor to overflow, realizing the evaporation curing from the inside to the outside, combined with the curing from the outside to the inside of the existing technology, the effect of two-way curing can be achieved, which can not only significantly improve the evaporation The curing efficiency can also effectively avoid the situation that the internal curing effect of the concrete is lower than the external one, improve the uniformity of curing, and make the quality of the finished concrete better. At the same time, during the water absorption process of the double seepage ball, the reinforcing ball can be released and evenly mixed into the slurry, thereby effectively increasing the coagulation force of the finished concrete and improving the structural strength
