Mixing equipment for micro-steel fiber reinforced concrete applied to lab

Abstract

The invention relates to mixing equipment for micro-steel fiber reinforced concrete applied to a lab. The mixing equipment comprises a mixing assembly and a feeding assembly; the mixing assembly comprises a main rack, a mixing bucket, a mixing shaft, a shaft rotating device and a bucket rotating device; and the feeding assembly comprises a secondary rack, a feeding tray, a feeding cylinder and a tray rotating device. The mixing equipment for the micro-steel fiber reinforced concrete applied to the lab, provided by the invention, can make micro-steel fibers be uniformly distributed in the concrete and can save materials so as to obtain high-quality micro-steel fiber reinforced concrete.

Description

technical field [0001] The invention relates to the field of concrete equipment, in particular to a mixing equipment for laboratory micro-steel fiber concrete. Background technique [0002] Concrete is a kind of concrete that uses cement as the main cementitious material, and water, dry materials (sand, gravel), if necessary, mixed with chemical admixtures and mineral admixtures, mixed in an appropriate proportion, after uniform mixing, compact molding and maintenance Hardened artificial stone. The micro-steel fiber reinforced concrete is a new type of multiphase composite material formed by adding randomly distributed micro-steel fibers into ordinary concrete. These randomly distributed micro-steel fibers can effectively prevent the expansion of micro-cracks inside the concrete and The formation of macroscopic cracks significantly improves the tensile, bending, impact and fatigue properties of concrete, and has good ductility. [0003] However, there are the following pro...

Problems solved by technology

[0003] However, there are the following problems when mixing the micro-steel fibers into the dry concrete material: ①The dispersion of the feeding is uneven. The traditional feeding method is to directly put the specified quality of the micro-steel fibers into the dry material during the mixing process. However, this kind of feeding The method will make the micro-steel fibers concentrate in the concrete part; ②The uniformity of the finished material is insufficient. The traditional equipment is composed of a mixing tank and a stirring shaft rotating in the mixing tank. Even if the micro-steel fibers are evenly spread on the surface of the dry concrete Mix it evenly into the dry concrete, so that the improvement effect of the concrete is limited due to uneven mixing
