Abstract

The invention relates to the field of building materials, and in particular relates to a concrete material for paving a road surface and a preparation method of the concrete material. The concrete material for paving the road surface comprises the following components, namely a gel material, aggregate and additives; the gel material consists of iron tailings, blast furnace slag, cement clinker and gypsum; the aggregate consists of waste rubber powder treated by NaOH, sand and pebbles; the additives comprise an air entraining agent, an early strength agent and a water reducing agent; and the waste rubber powder is neutral rubber powder which is a rubber powder suspension treated by using NaOH. The concrete material disclosed by the invention has the beneficial effects of achieving reasonable utilization of waste resources, effectively utilizing the iron tailing, waste rubber powder and other resources, solving the problem of treating the iron tailings, improving the performances, such as impact resistance, antifreezing property and anti-cracking property of concrete on the basis of saving the production cost, and prolonging the service life.

Description

[0001] technical field [0002] The invention relates to the field of building materials, in particular to a concrete material used for laying road surfaces, and also to a preparation method of the concrete material. Background technique [0003] Concentrated mixing of concrete is a major change in the production mode of construction engineering. The application quantity and proportion of commercial concrete indicate the level of concrete industry production in a country. Practices at home and abroad have shown that the use of commercial concrete can generally increase labor productivity by more than double, save cement by 10% to 15%, and reduce project costs by about 5%. At the same time, it can ensure project quality, save construction land, reduce dust pollution, and realize civilized construction. . By the early 1980s, the application of commercial concrete in economically developed countries reached 60% to 80% of the total concrete. [0004] my country's concrete mi...
