Production technology of building block

Abstract

The invention discloses a production technology of a building block. The production technology comprises the following steps: A, preparing materials: preparing the following materials in parts by weight: 150-250 parts of phosphorus slag, 50-100 parts of river sand, 50-75 parts of cement, 100-150 parts of fly ash, 30-50 parts of fluorgypsum, 8-15 parts of ceramsite, 30-60 parts of bentonite, 5-10 parts of a polycarboxylate water reducer, 5-15 parts of an anti-cracking agent and 60-120 parts of water; B, blending the materials; C, stirring the materials; D, moulding; E, curing; F, discharging. With the slag as a main raw material, on one hand, the production cost is reduced, and on the other hand, the slag stacking problem is solved; due to addition of the river sand and the anti-cracking agent, the produced building block can be guaranteed to have good load-bearing capacity, so that the building block can be applied to a load-bearing wall; due to addition of the water reducer, the usingamount of water in the building block producing process can be reduced, so that the using amount of a water resource is reduced.

Description

technical field [0001] The invention relates to a block making process and belongs to the technical field of building materials. Background technique [0002] The county and city where our company is located is rich in mineral resources, and there are countless enterprises mining and smelting mineral resources. A large amount of slag obtained after smelting of mineral resources is stacked in the open air, which not only occupies a large amount of land, but also easily causes environmental pollution. As a building wall material, blocks are indispensable in urban construction. A large number of existing blocks still use soil such as clay as raw materials, and a large amount of mining has caused serious soil loss. For this reason, under the premise of avoiding soil loss, how to rationally use slag as a raw material to produce building blocks has become the research focus of various enterprises. At present, a large number of energy-saving blocks have appeared on the market, bu...
