Abstract
The invention discloses dry-mixed common masonry mortar based on construction solid waste recycled fine aggregate, which comprises the following components in parts by weight (kg/t): 90-200 parts of 42.5-grade ordinary portland cement, 50-100 parts of secondary fly ash, 800 parts of recycled fine aggregate and 6-12 parts of water-retaining thickening material. The recycled fine aggregate is formed by crushing waste concrete, and has a particle size of less than 4.75mm, wherein the content of particles with a particle size of 2.36-4.75mm is 10-15%, and the content of particles with a particle size of 0.075-2.36mm is 70-80%. The invention utilizes the building concrete waste to change waste into valuable to replace natural sand, thereby not only protecting the natural environment, but also reducing the cost of the mortar.
Description
Technical Field
The invention relates to mortar, in particular to dry-mixed common masonry mortar based on construction solid waste recycled fine aggregate, and belongs to the field of building materials.
Background
The mortar for building blocks such as bricks, stones and building blocks into masonry is called masonry mortar, which plays roles of bonding, lining and force transmission and is an important component of the masonry. Generally, the sand is prepared by mixing natural sand, a cementing material and an additive. With the development of infrastructure construction, the demand for natural sand resources is increasingly vigorous, however, the natural sand resources are non-renewable resources in a short time, and the natural sand resources are gradually lacking due to the fact that the country forbids the exploitation of natural sand in river reach in plain text. On the other hand, huge construction waste, particularly concrete waste, has become a huge burden for economic and social development in China, and under the comprehensive action of natural resources and environmental protection problems, resource recycling has become the main melody for social development at present. Therefore, it is necessary to research and use the concrete waste to replace the natural sand, so as to alleviate the shortage of natural sand resources.
Disclosure of Invention
The purpose of the invention is as follows: solid waste is utilized, and the environment is protected.
In order to achieve the purpose, the invention adopts the following technical scheme: a dry-mixed common masonry mortar based on construction solid waste recycled fine aggregate is characterized by comprising the following components in parts by weight (kg/t):
90-200 parts of 42.5-grade ordinary portland cement, 50-100 parts of secondary fly ash, 800 parts of recycled fine aggregate and 6-12 parts of water-retaining thickening material.
The recycled fine aggregate is formed by crushing waste concrete, and has a particle size of less than 4.75mm, wherein the content of particles with a particle size of 2.36-4.75mm is 10-15%, and the content of particles with a particle size of 0.075-2.36mm is 70-80%.
Compared with the prior art, the invention has the beneficial effects that: the waste building concrete is used to replace natural sand, so that the natural environment is protected and the cost of mortar is reduced.
