Production method of cement-based foamed concrete insulation block

Abstract

A production method of a cement-based foamed concrete insulation block is characterized by comprising the following steps: preparing cordierite powder and spinel type ferrite; preparing infrared radiating ceramic powder; performing surface treatment on hollow glass microbeads; pre-foaming polystyrene masterbatch; and with fly ash and cement as main raw materials and the infrared radiating ceramicpowder, the hollow glass microbeads and the foamed polystyrene masterbatch as auxiliary materials, preparing mortar; then filling into a mould, vibrating, autoclaving and drying to obtain the cement-based foamed concrete insulation block. The cement-based foamed concrete insulation block contains a large number of uniformly distributed micropores, shows high physical and mechanical properties, hasthe characteristics of light weight, good insulation, high specific strength and the like, and has a very high infrared radiation characteristic and very high adiabaticity.

Description

technical field [0001] The invention relates to the construction field, in particular to a production method of cement-based foamed concrete thermal insulation blocks. Background technique [0002] Commonly used building materials such as concrete, mortar, masonry, and roofing waterproof and thermal insulation materials have an average absorption rate as high as 85%-95% in the entire solar spectrum range, which is a gray body close to a black body. Their ability to reflect visible light and infrared light is very low, and they absorb more heat from solar energy than they emit to the outside space, resulting in continuous accumulation of heat and transfer to the inside, and due to temperature differences, the material expands and contracts with heat and contraction, resulting in a shortened lifespan. With the increasing development of residential construction and the increasing popularity of air conditioners, this will consume a lot of energy (in many developed countries, the...
