Abstract

The invention provides an alkali activated slag foamed cement product and its preparation method. The product is prepared from the following raw materials by weight: 60 to 75% of an alkali slag cementing material, 0.5 to 1% of a composite admixture, 8 to 15% of foam and 16 to 25% of water. The alkali slag cementing material is prepared from the following raw materials by weight: 93.0 to 96.0% of slag powder, 1.0 to 2.0% of a water reducing agent and 2.0 to 5.0% of alkali powder particles. According to the invention, in a formula, the slag powder and the alkali powder particles which are generally used as industrial wastes are utilized as the cementing material for the foamed cement; the product has excellent early-strength mechanical performance and thermal insulation performance, stable and uniform foam and a short setting time; cost is reduced while production efficiency is improved. The product provided in the invention can be processed and molded in a factory or directly casted after mixing on the spot and is applicable to a non-load-bearing wall building block, a floor heating insulation layer and a roof insulation layer of a building or to preparation of various insulation materials.

Description

technical field [0001] The invention relates to a foamed cement and a preparation method thereof. Background technique [0002] Foamed cement is a new type of lightweight thermal insulation material that contains a large number of closed pores formed by fully foaming the foaming agent through a foaming system, and then using cement-based cementitious materials to add foam and natural curing. In construction applications, foamed cement can be used as thermal insulation materials for non-load-bearing structures such as roofs, walls, walls, and floors. It has low bulk density, good thermal insulation performance, sound insulation and noise reduction, and good seismic performance. Excellent performance of automatic humidity adjustment. [0003] Existing foamed cement has the problem of high cost in application and construction. The cement, gypsum powder and other materials are generally used in the batching. The large-scale use of cement and gypsum powder increases the cost of ...
