Fly ash concrete small hollow block and preparation method thereof

Abstract

The invention relates to a fly ash concrete small hollow brick and a preparation method thereof, which are particularly suitable for a frame structure and high-rise building block filled wall, and belong to the field of building industry. Compared with the conventional preparation method for a fly ash block, the preparation method has the advantages that: the doping amount of fly ash is large, the common ash doping amount in China is 20 to 60 percent, and the ash doping amount in the preparation method is 80 percent; strength is high; the strength grade is more than or equal to MU7.5; wet-discharged fly ash is not required to be dried again, so that cost is saved; and any other additive except the fly ash is not required to be added, so that the current conditions that the doping amount of the solid waste fly ash in a building material block is small and the additive is needed are avoided. The fly ash concrete small hollow brick has the characteristics of high strength, energy conservation, thermal insulation, light weight, good sound insulation effect and waste recycling, is easy to widely use and popularize, and can be suitable for the frame structure and high-rise building block filled wall and the like, production cost is effectively reduced, and the construction cost of a building is reduced.

Description

technical field [0001] The invention relates to a small-sized hollow brick of fly ash concrete and a preparation method thereof, which is especially suitable for frame structures and high-rise building block filling walls, and belongs to the field of construction industry. Background technique [0002] As people pay more attention to building energy saving and living environment, industrial solid waste replaces clay as building materials, and people pay more and more attention to it because of its environmental protection and practicality. Air concrete bricks and other bricks. However, all kinds of fly ash bricks currently used need to add admixtures to increase the consolidation force due to the complex ingredients, so as to improve their strength, and the ash mixing rate in the process is not high. For fly ash blocks, due to the addition of additives, the cost increases, the increase in concrete increases the weight, the economic benefit decreases and the ash content is n...

However, all kinds of fly ash bricks currently used need to add admixtures to increase the consolidation force to improve their strength due to the complex ingredients, and the ash mixing rate in the process is not high.

For fly ash blocks, due to the addition of additives, the cost increases, the increase in concrete results in an increase in weight, the economic benefit decreases and the ash content is not high
