Limestone powder dry powder mortar

Abstract

The invention relates to a dry powder mortar of stone dust, which is characterized in that the dry powder mortar of the stone dust is mainly formed by cement, fly ash, yellow sand, stone dust or mortar thickening powder. The invention initially takes the stone dust as the raw material of the dry powder mortar, and the mechanical property of the stone dust in the mortar is more excellent than the yellow sand, thereby changing waste into valuables. The invention is economical and environment-friendly.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a stone powder dry powder mortar. Background technique [0002] Stone powder is the waste produced in the process of producing stones in the quarry. The piled up stone powder causes serious pollution to the environment, and the powder content of stone powder is relatively large, so people do not use stone powder as a raw material for dry powder mortar, thinking that it will affect the strength and other factors. Performance is adversely affected. [0003] In the past, yellow sand and some additives were mainly used to produce dry powder mortar. As far as yellow sand is concerned, medium sand (fineness modulus 2.3-3.0) is required. Because of the large demand for yellow sand in building construction such as wet-mixed concrete, this makes the supply of medium sand insufficient. . [0004] After trial mixing, research and adjustment of different dosages of the same st...
