Abstract

The invention relates to a method for producing multifunctional concrete from household garbage power generation waste residues, and belongs to the technical field of novel concrete materials and environmental engineering. The method comprises the following steps: mixing the household garbage power generation waste residues with natural sand to obtain mixed sand; mixing the household garbage power-generation waste residues with the grain sizes greater than 5 mm with crushed stones to obtain mixed crushed stones; mixing natural zeolite powder with brucite fibers to prepare a thickening early-strengthening anti-cracking self-curing agent; mixing a polycarboxylate superplasticizer with ultrafine mineral powder to obtain a liquid water-reducing plasticity-maintaining agent; weighing cement, coal ash, silicon powder, mineral powder, the thickening early-strengthening anti-cracking self-curing agent and the mixed crushed stones in a mass ratio, and pouring into a stirrer successively for uniformly stirring to obtain the multifunctional concrete. The concrete prepared by the method has characteristics of self-compaction, self-curing, low hydration heat, low shrinkage, high durability and high plasticity retention property and can be applied to architectural engineering, civil engineering, traffic engineering, city construction engineering and the like. The method has very high economic and social benefits.

Description

[0001] technical field [0002] The invention relates to a method for producing multifunctional concrete by utilizing domestic garbage power generation waste slag, and belongs to the technical field of new concrete materials and environmental engineering. Background technique [0003] Domestic waste slag is the waste residue discharged by incinerating power generation with domestic waste as fuel. At present, the waste-to-energy plants in my country discharge about 500-700kg of slag per day. For example, there are currently three household waste power plants in Guangzhou, with an annual discharge of 600,000 to 700,000 tons of waste slag. Such a large amount of waste piled up in the open air has caused serious water pollution and air pollution. Contents of the invention [0004] The purpose of the present invention is to propose a method for producing multifunctional concrete by using domestic garbage power generation waste slag, using domestic concrete raw materials and indu...
