Abstract

The present invention relates to the technical field of building materials, and in particular relates to a lightweight aggregate concrete small hollow block with a large doping amount of fly ash slag. The hollow block comprises the components of: 20-50 parts of fly ash, 35-70 parts of blaster furnace slag, and 8-15 parts of cement. The invention comprehensively utilizes fly ash and blaster furnace slag produced in heat-engine plant, and has large utilization amount of waste; the technology can be used in industrial production to reach high utilization rate and large amount of industrial wastes; the prepared products has stable compressive strength of above 5MPa, density of less than 800kg / m<3>, and excellent properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a small-sized hollow block of lightweight aggregate concrete with a large amount of fly ash slag and a production method thereof. Background technique [0002] Fly ash is industrial waste slag discharged from thermal power plants. Due to its large volume and wide area, especially serious environmental pollution and land occupation, countries all over the world have attached great importance to the comprehensive utilization of fly ash for a long time. As the world's largest thermal power generation country, our country has been carrying out a lot of research and product development in the comprehensive utilization of fly ash since the 1960s. For example, the research and development of fly ash aerated blocks, fly ash autoclaved (steamed) bricks, fly ash burn-free and steam-free bricks, fly ash sintered bricks, fly ash ceramsite, etc., are my country's fly ash The compre...
