Abstract

The invention relates to a method for producing a concrete channel prefabricated part from mineral slag. The method is characterized in that the concrete channel prefabricated part is prepared from the following raw materials in parts by weight: 60-70 parts of fine and coarse aggregate, 10-20 parts of 42.5 sulfoaluminate cement, 5-10 parts of fly ash, 5-10 parts of slag micropowder, 1-3 parts of early-strength admixture, 1-3 parts of high efficiency water reducing agent and 0.1-0.5 part of defoaming agent. The high efficiency water reducing agent is a calcium lignosulphonate water reducing agent. The concrete channel prefabricated part has the advantages of low cost, excellent properties, stable quality, excellent compression strength, excellent compression strength, excellent freeze resistance and excellent water impermeability. The method aims to further enhance the standard construction of irrigation projects, comprehensively enhance the construction level and management and protection level of agricultural hydraulic engineering in China, increase the utilization ratio of irrigation water and implement high-efficiency utilization of water resources.

Description

technical field [0001] The invention belongs to the field of concrete processing, and in particular relates to a method for producing concrete trench prefabricated parts by utilizing slag, which can be widely used in agricultural engineering and water conservancy construction engineering. Background technique [0002] Slag is a kind of industrial solid waste, which is the waste slag discharged during the blast furnace ironmaking process. The output varies with the smelting technology and the ore grade, and is generally 25%-90% of the pig iron output. According to this, the annual output of slag in my country is estimated at About 60 million tons, slag is mainly used as cement mixing material, slag fine powder can not only produce high-quality slag cement, but also can be widely used in concrete mixing plants, construction products and concrete engineering fields. [0003] With the vigorous development of modern agriculture and water conservancy infrastructure in our country, ...
