A concrete anti-crack construction method and its aggregate blowing cooler

Abstract

The invention provides an anti-cracking construction method for concrete. The method includes the steps that firstly, mixed concrete grout and aggregate blow-cooled by an aggregate blow-cooling machine are stirred and mixed; secondly, the cooled concrete grout is poured onto a built mold through a discharging device and molded through a mold pressing device; thirdly, a steel wire mesh is laid on the surface layer of molded concrete; fourthly, a concrete curing agent is sprayed to the surface layer of the molded concrete; fifthly, a foam insulating material is sprayed to the outer layer of the sprayed concrete curing agent, and the outer layer of the foam insulating material is coated with anti-seepage glue and rolled and pressed by a press roller; sixthly, an insulation board is laid on the outer layer of the foam insulating material, and a binder is arranged between the insulation board and the anti-seepage glue in a coating mode; and seventhly, the outer side of the insulation board is coated with an anti-aging sealing layer. A concrete structure manufactured through the method is good in insulation performance and high in anti-aging performance. Cracks are not prone to being caused in the construction and using processes of the constructed concrete structure.

Description

technical field

[0001] The invention relates to the technical field of building construction, in particular to a concrete anti-cracking construction method and an aggregate blowing cooler thereof. Background technique

[0002] With the progress of society and the development of science and technology, large-volume situations in concrete construction are becoming more and more common in the process of engineering construction. The requirements for construction technology are relatively high, and the difficulty of construction is increasing. Poor temperature stress cracks. Especially the control of the concrete temperature after the pouring of the concrete, if the temperature difference between the inside and outside of the concrete is large, the concrete will produce cracks during the solidification process; the quality of the concrete cannot be effectively guaranteed. In addition, the maintenance after the concrete pouring is also very important. Since the concrete is easil...

Embodiment 1

[0039] A concrete anti-cracking construction method, comprising the steps of:

[0040] Step 1: Stir and mix the stirred concrete slurry with the aggregate cooled by the aggregate blower; preferably, the mixing of the concrete slurry and the mixing with the aggregate is carried out by a concrete mixing station, and the concrete mixing The station includes 5 major systems including mixing host, material weighing system, material conveying system, material storage system and control system and other necessary auxiliary facilities. Concrete mixing plant adopts floor aggregate measurement. Compared with station aggregate measurement, its measurement method reduces four intermediate links, and it is vertical feeding measurement, which saves measurement time and greatly improves production efficiency. The cooling of the aggregates is carried out by an aggregate blowing cooler, and the cooling in the form of blowing cooling can make the aggregates of the inner layer and the outer laye...
