Problems solved by technology

[0003] At present, in the domestic market, permeable concrete sheets have the problem of incompatibility between water permeability and strength. Under the premise of achieving the national water-permeable effect, it is difficult for the strength to exceed the C30 grade, which hinders the development of permeable concrete in key structures. and application, steel slag is difficult to be applied to the main structure due to its low strength
The commonly used solution is to add a certain amount of high-strength organic reinforcing agent, which will greatly reduce the durability of concrete.

Abstract

The invention discloses high-strength highly-permeable inorganic concrete and a preparation method thereof. The high-strength highly-permeable inorganic concrete comprises, by weight, 60-120 parts of water, 200-500 parts of cement, rubble, sand, 100-200 parts of mineral powder, fly ash, 1200-1800 parts of steel slag, 100-300 parts of quartz sand, 30-80 parts of a reinforcing agent, 10-30 parts of a water reducing agent and stones. According to the high-strength highly-permeable inorganic concrete, the mineral powder and the reinforcing agent are utilized to equivalently replace cement, the grading proportion of a permeable concrete gelled material can be improved, permeable concrete with good fracture resistance and permeability performance is obtained, cement consumption is lowered, the cost is saved, the problem that the steel slag and mineral waste residues serve as waste to cause secondary pollution to the environment is solved, industrial waste is effectively utilized, and good environmental benefits are achieved.

Description

technical field [0001] The invention relates to a high-strength and high-permeability inorganic concrete and a preparation method thereof, belonging to the field of construction engineering. Background technique [0002] Permeable concrete, also known as porous concrete, sand-free concrete, and permeable floor, is a kind of porous lightweight concrete made by mixing aggregate, cement and water. It does not contain fine aggregate and is covered by coarse aggregate. Thin layers of cement paste are bonded to each other to form a honeycomb structure with uniform distribution of pores, so it has the characteristics of air permeability, water permeability and light weight. [0003] At present, in the domestic market, permeable concrete sheets have the problem of incompatibility between water permeability and strength. Under the premise of achieving the national water-permeable effect, it is difficult for the strength to exceed the C30 grade, which hinders the development of permea...
