Preparation process of internal transition curing type concrete

Abstract

The invention discloses a preparation process of internal transition curing type concrete, and belongs to the field of concrete preparation technologys. The preparation process of the internal transition curing type concrete comprises a guiding-assisting pre-burying device, the guiding-assisting pre-burying device comprises a carrier air bag pipe and a plurality of guiding-assisting rods, and the guiding-assisting rods are evenly arranged at the outer end of the carrier air bag pipe in a sleeve mode. According to the reparation process, the guiding-assisting pre-burying device is pre-arranged inside a concrete member according to requirements, the carrier air bag pipe is subjected to air exhaust and taken out before the concrete member is solidified and formed, and the guiding-assisting rods are uniformly formed inside the concrete member from outside to inside, so that on one hand, normal solidification and forming of concrete are not easily affected, on the other hand, in the curing process of the concrete member, steam and heat in an external structure of the concrete are transmitted to an internal structure of the concrete in an accelerated mode through the guiding-assisting rods, the concrete curing efficiency is improved, meanwhile, the difference between the internal curing effect and the external curing effect of the concrete is effectively reduced, curing uniformity is improved, and then the quality of concrete finished products is improved.

Description

technical field [0001] The invention relates to the field of concrete preparation technology, and more specifically, relates to an internal curing type concrete preparation technology. 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. . [0003] Concrete curing is to artificially create certain humidity and temperature conditions, so that the newly poured concrete can be normal or accelerate its hardening and strength growth. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and the hydration of cement requires certain temperature and humidity conditions. If this condition does not exist in the surrounding environment, the concrete needs to be cured manually. [0004] Con...

Problems solved by technology

[0005] However, during the steam curing process, steam and temperature are transmitted into the concrete components from the outside to the inside, which will easily lead to the external curing effect of the concrete components being better than the internal, the effect of steam curing is not uniform, and a certain strength difference is formed inside and outside the concrete components
