Flyash excitant and production process thereof

Abstract

A powdered coal ash exciting agent for concrete is proportionally prepared from salty mud as the dregs generated by preparing chloric alkali, aluminium sulfate dregs, lime dregs and ardealite through drying, mixing, stirring and grinding. It has very low cost.

Description

technical field [0001] The invention belongs to the field of building materials such as cement and concrete, and in particular relates to a concrete admixture and a cement additive for stimulating the chemical activity of fly ash and increasing its content in concrete and cement. Background technique [0002] At present, there are many research results on the comprehensive utilization of industrial waste fly ash, most of which focus on the core issue of how to improve the activity of fly ash. The specific measures include mechanical activation, physical activation and chemical activation. The existing fly ash activator, the patent No. is ZL03133657.4, is composed of sodium sulfate, calcium chloride, sodium chloride, superplasticizer, calcium lignosulfonate and phosphogypsum. Although this kind of activator can effectively stimulate the potential activity of fly ash and increase the amount of fly ash in concrete and its products, however, since the basic composition of this a...
