Premixed mortar mixture for buildings and preparation method thereof

Abstract

The invention provides a premixed mortar mixture for buildings and a preparation method thereof, and relates to the technical field of building materials. The premixed mortar mixture for buildings comprises the following raw materials in parts by weight: 10-15 parts of cement, 20-25 parts of sintered brick powder, 10-14 parts of fly ash, 50-55 parts of quartz sand, 20-25 parts of crushed stone powder, 1-2 parts of a concrete admixture, 20-30 parts of water and 10-15 parts of a water-retaining thickener. By simultaneously adding the concrete admixture and the water-retaining thickener, the mortar mixture has water-retaining property, thixotropic lubricity and dispersion suspension property, meets the construction performance of mortar, has the characteristics of long-time storage and transportation resistance, high strength and low shrinkage rate, solves the difficult problem of construction waste treatment, and is simple in process steps, the method is friendly to the environment; and the production cost of the mortar is reduced.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a ready-mixed mortar mixture for building and a preparation method thereof. Background technique [0002] In recent years, some large cities in my country have begun to promote ready-mixed mortar. The production and use of ready-mixed mortar meets the development requirements of a circular economy and a resource-saving society. It has realized industrial production and ensured the stability of quality from the source. It has many advantages such as good operability, less on-site pollution, and effective improvement of project progress. Concrete admixtures are chemical substances that are mixed in the process of mixing concrete, accounting for less than 5% of the cement mass, and can significantly improve the performance of concrete. With the characteristics of less investment, quick results, and remarkable technical and economic benefits, with the continuous advancement of scien...
