Abstract

The invention discloses a lightweight aggregate foam concrete which is composed of the following materials in parts by weight: 100-300 parts of cement, 1-150 parts of admixture, 60-250 parts of water, 1-10 parts of additive and 1-11 parts of foaming agent, as well as a lightweight material by a dosage accounting for 5%-60% of the total volume. The admixture comprising PC32.5 cement, coal ash and the like is produced from industrial waste materials such as coal ash, slag powder and clinker, so that discharge and bulk deposition of the industrial waste materials are effectively reduced and the environmental pollution is greatly reduced; therefore, good environmental protection benefit and social benefit are achieved. More importantly, expensive sulfoaluminate cement is replaced by low-cost materials, so that the cost of producing the lightweight aggregate foam concrete is greatly reduced; the performance effect of the product is extremely obvious and the physical properties of the cement is greatly improved; as a result, the outside erosion resisting capability of the concrete is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of foam concrete and foam concrete lightweight materials, and in particular relates to a lightweight aggregate foam concrete and a production method thereof. technical background [0002] At present, foamed concrete is a widely used light-weight thermal insulation material. It has light weight, good thermal insulation performance and low price, and has become the leading product of environmental protection and energy-saving wall materials. Promoting the use of this new type of wall material can not only improve building functions, improve construction quality and construction efficiency, meet the needs of modernization and functionalization of the construction industry, but also effectively utilize existing industrial waste resources and improve resource utilization. [0003] With the continuous development of foam concrete production and application, various kinds of foam concrete emerge in endlessly, and p...
