Description

Steaming-free high-strength recycled concrete preparation equipment Technical Field The application relates to the field of recycled concrete, in particular to a non-autoclaved high-strength recycled concrete preparation device. Background With the increasing demand of the building industry for environmental protection and sustainable development, the application of recycled aggregate is paid attention to gradually, however, in the production process of traditional recycled concrete, a high-temperature steam curing process is generally required for ensuring strength, so that not only energy consumption is increased, but also the possibility of on-site instant production is limited, and in recent years, a great deal of research is developed for the problem at home and abroad, and in an attempt is made to reduce energy consumption and improve efficiency by improving the formulation design, optimizing the production process and other modes, but certain limitation still exists in practical engineering, so that the development of recycled concrete production equipment capable of realizing high-strength performance without depending on an external heat source is particularly important. The conventional common solutions mainly comprise the following steps of adding a high-efficiency water reducing agent or other chemical additives into a common mixture to enhance early hardening speed so as to avoid the increase of cracking risk caused by long-time natural air drying, adopting a sand-stone mixing proportion with higher compactness to compensate partial cohesive force possibly lost due to lack of additional temperature conditions, and rapidly removing excessive water by means of a vacuum dehydration device so as to enable an internal structure to be more compact and stable. The measures have the characteristics that the first method is convenient to operate and relatively low in cost, but quality problems or economic burden is increased due to improper control of the medicine amount, the second method is more important to the adjustment of the properties of raw materials, but the fluidity is possibly reduced to influence the pouring effect, and the third method can obviously improve the quality of the final product, but has higher equipment investment and complex maintenance and is not beneficial to popularization of small and medium enterprises. The conventional means generally have the problems of limited application range, high additional cost, high operation difficulty and the like, and cannot meet the requirements of modern large-scale industrial production. Disclosure of utility model The application aims to solve the problems that the conventional means provided in the background art are generally limited in application range, high in additional cost, high in operation difficulty and the like, and cannot meet the requirements of modern large-scale industrial production.
