Concrete material prepared by utilizing wastes and preparation method of concrete material

Abstract

The invention relates to the technical field of concrete materials and discloses a concrete material prepared by utilizing wastes and a preparation method of the concrete material. The concrete material disclosed by the invention comprises the following raw material components in parts by weight: 50-60 parts of coarse aggregate, 5-15 parts of cement, 15-30 parts of tailing sand, 0.1-0.3 part of straw, 0.2-0.4 part of EPS granules, 3.2-10.3 parts of additives, 1.2-2.0 parts of sodium hydroxide solution, 1.0-1.2 parts of sodium silicate solution and 5-15 parts of water. The concrete material disclosed by the invention is economic and readily available in raw materials, high-efficiency and environmental-friendly and has excellent compressive strength and breaking strength.

Description

technical field [0001] The invention relates to the technical field of concrete materials, in particular to a concrete material prepared from waste and a preparation method thereof. Background technique [0002] With the rapid development of our country's economy, people's living standards continue to improve, and the grain output increases year by year. After the grain is harvested, a large amount of straw is produced and generally incinerated, which not only causes a lot of waste of straw resources, but also produces incineration smoke. It also pollutes the ecological environment extremely. [0003] At the same time, the world's annual consumption of polystyrene products exceeds one million tons, most of which are used to make EPS polystyrene boards, which are wall insulation materials. Its products are difficult to degrade in nature, and will cause secondary pollution to natural conditions such as soil and water sources. While the discarded polystyrene products are incr...

AI Technical Summary

Problems solved by technology

[0004] With the vigorous development of China's industry, my country's steel production capacity has been among the top in the world for many years in a row, while the iron tailings and waste sand and gravel produced in steelmaking and ironmaking are directly abandoned and piled up. At present, it has exceeded 10 billion tons. Due to recycling rate is only about 14%, so it caused a lot of waste of resources

A large amount of tailings will not only occupy valuable land resources, but also the chemical reagents added to the tailings for screening minerals will also cause serious pollution to the natural environment. Therefore, the problem of recycling iron tailings sand also needs to be solved urgently

[0005] As for the construction industry, the required building materials need to consume a lot of resources such as cement, stone sand, etc. These building materials also have a large number of quite serious pollution links in the production process
