Manufacturing method of solid waste based cementing material concrete and quantitative feeding device

Abstract

The invention discloses a manufacturing method of solid waste based cementing material concrete and a quantitative feeding device. According to the manufacturing method, a solid waste based cementingmaterial is adopted, and the solid waste based cementing material comprises the following raw materials: 30-60% of granulated blast furnace slag, 30-50% of steel slag, 10-20% of industrial by-productgypsum, 3-10% of fly ash and 3-10% of iron tailings, the preparation method comprises the following processing steps of stirring the solid waste-based cementing material, inspecting the solid waste-based cementing material, storing the solid waste-based cementing material, preparing premixed mortar and preparing concrete. The quantitative feeding device comprises a workbench, a quantitative feeding mechanism is arranged on the upper part of the workbench, a discharging mechanism is arranged below the quantitative feeding mechanism, and a material distributing mechanism is arranged below the discharging mechanism. The manufacturing method and the quantitative feeding device have the beneficial effects that the working efficiency is improved, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of concrete production, and more specifically, relates to a production method of solid waste-based cementitious material concrete and a quantitative feeding device. Background technique [0002] Concrete refers to the artificial stone material that is made by mixing cementitious materials with water, fine aggregate, and coarse aggregate, adding chemical admixtures and mineral admixtures in appropriate proportions, uniformly stirring, compacting, and curing hardening. Divided into C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 a total of fifteen strength levels. [0003] In the existing concrete production methods, the cementing materials generally used are cement, lime paste, clay, etc., and the cost is relatively high, and when mixing concrete, there are one-time feeding method and second-time feeding method.

Problems solved by technology

[0003] In the existing concrete production methods, the cementing materials generally used are cement, lime paste, clay, etc., and the cost is relatively high, and when mixing concrete, there are one-time feeding method and second-time feeding method. All the raw materials are put into the mixer, mixed and stirred to form concrete. The secondary feeding method is divided into two steps. First, the cementitious material and fine aggregate are put into the mixing drum according to a certain proportion, and an appropriate amount of water is added to fully Stir to form mortar first, then put the coarse aggregate into the mixing drum, and mix it evenly to form concrete. Compared with the concrete mixed by the one-time feeding method, the strength of the concrete mixed by the second feeding method can be increased by about 15%. , can save 15% to 20% of cement. When using the secondary feeding method for concrete mixing, a large amount of raw materials are generally put in directly through manual or mechanical equipment, and then mixed. There is a deviation in the mixing ratio, which affects the quality of the concrete. quality
