High-performance volcanic ash concrete and production process thereof

Abstract

The invention discloses high-performance volcanic ash concrete and a production process thereof and belongs to the field of non-metallic mine deep processing. The high-performance volcanic ash concrete comprises a gelling material, sand, stones, water and an additive, wherein the gelling material comprises cement, high-quality volcanic ash and silicon ash; the additive is an efficient water reducer; the constitution of each raw material is as follows: the using amount of the water is less than or equal to 150kg; the total amount of the gelling material is 300kg / m<3> to 350kg / m<3>; the using amount of the cement is 50 to 60 percent of the total amount of the gelling material; the using amount of the high-quality volcanic ash is 30 to 40 percent of the total amount of the gelling material; the using amount of the silicon ash is 2 to 5 percent of the total amount of the gelling material; and the using amount of the efficient water reducer is 0.5 to 1.0 percent of the total amount of the gelling material. The high-performance volcanic ash concrete prepared by the production process disclosed by the invention has better anti-permeability, chemical corrosion resistance and durability, and good falling-keeping effect; the used raw materials are low in cost and high in cost performance.

Description

technical field [0001] The invention relates to the field of material science and engineering and the field of deep processing of non-metallic ore, in particular to a high-performance pozzolanic concrete and a production process thereof. Background technique [0002] In recent years, with the development of large-scale infrastructure construction in my country, the output of concrete has increased sharply, resulting in an increasing shortage of high-quality admixtures. In many areas, resources such as fly ash and slag are in short supply. Therefore, there is an urgent need to develop a new admixture substitute that is easy to obtain, high-quality and low-cost. Volcanic ash is fine debris produced by volcanic activities, and its main components are rocks, minerals, and volcanic glass fragments, with a diameter of less than 2mm. In my country, volcanic ash resources are extremely rich in the volcanic distribution area from the Heilongjiang River in the north to Hainan Island....
