Abstract

The invention relates to the technical field of building materials, and particularly discloses environment-friendly anti-freezing concrete and a preparation method thereof. The environment-friendly anti-freezing concrete is prepared from the following components in parts by weight: 420 to 570 parts of cement, 572 to 656 parts of sand, 825 to 940 parts of stone, 170 to 210 parts of water, 51 to 70 parts of admixture, 58.8 to 80.6 parts of admixture, 40 to 60 parts of waste rubber particles and 45 to 60 parts of anti-freezing agent, the anti-freezing agent comprises the following components: modified starch, graphene oxide, iron tailing powder, eggshell membrane, sodium hydroxide, urea and cellulose; the preparation method comprises the following steps: adding the admixture and the antifreeze agent into water, and uniformly mixing to obtain a premix; mixing the cement, the sand, the stones, the admixture and the waste rubber particles, adding the premix, and uniformly mixing to obtain the environment-friendly anti-freezing concrete. The environment-friendly anti-freezing concrete has the advantages that waste rubber is recycled, the anti-freezing performance and the anti-seepage performance are high, and automobile exhaust can be purified.

Description

technical field

[0001] The application relates to the technical field of building materials, more specifically, it relates to an environment-friendly frost-resistant concrete and a preparation method thereof. Background technique

[0002] With the rapid development of my country's economy, environmental problems are becoming more and more serious, and the output of various wastes has increased sharply. Therefore, recycling wastes is an important way to protect natural resources and promote sustainable development. The output of waste tires in my country reached 330 million in 2015, and the recovery rate was only less than 50%. Recycling waste tires as raw materials for concrete production has a large amount of recycling and can improve the road performance of concrete.

[0003] Concrete freeze-thaw damage is a common disease in concrete structure engineering in cold areas, especially in coastal areas, where the wind is strong and the temperature is low, and the concrete stru...
