Embodiment 1

[0026] (1) Install a dust suction device on the crushing and screening device to absorb stone powder in the process of crushing and screening stone materials, so as to reduce the content of stone powder in the machine-made mountain sand;

[0027] (2) adding quartz sand to the machine-made hill sand that the obtained stone powder content reduces, to improve the gradation of the machine-made hill sand;

[0028] (3) Adding fly ash to the machine-made mountain sand with improved gradation, the mass fraction of obtained stone powder is 11%, the mass fraction of particles with a particle size of 0.15 to 0.3 mm is 16%, and the mass fraction of fly ash is 8% improved mountain sand;

[0029] (4) Mix 100 parts of the improved mountain sand with 14.3 parts of cement and 17.2 parts of water evenly to obtain an improved machine-made mountain sand mortar that can be used for wall plastering.

[0030] The obtained mortar is plastered according to the construction processes such as base trea...

Abstract

The invention discloses an improved machine-made hilly sand mortar for wall plastering and a preparation method of the improved machine-made hilly sand mortar, the grading is improved by adding silicasand, the content of rock flour is controlled by adding a dust collection device, the flowability of the mortar is improved by adding coal ash, the measures are taken to overcome the defects of the machine-made hilly sand, the wall plastering quality is improved, the improved machine-made hilly sand is directly applied to the wall plastering at the same time, adhering a fiberglass net is not needed, and the cost of the plastering construction period and the economic cost are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an improved machine-made mountain sand mortar used for wall plastering. Background technique [0002] With the continuous development of my country's infrastructure construction, the contradiction between the supply and demand of existing river sand resources is becoming more and more serious, especially in Yunnan, Guizhou and Sichuan, where river sand resources are scarce, and purchasing river sand from other provinces will lead to a large increase in cost. It is a development direction that machine-made mountain sand replaces river sand for wall plastering. [0003] Machine-made mountain sand is made by crushing and screening stone materials. It has the characteristics of various particle shapes, large specific surface area, and poor gradation, which leads to rough plastering on the wall, and the finish does not meet the specification requirements; at t...
