Problems solved by technology

[0003] At present, on the one hand, the price of cement is rising year by year, and the process of making cement will cause pollution to the environment; on the other hand, in remote Tibetan areas and pastoral areas in the west and north of my country, cow dung is used as fuel after drying, which is the main source of human life. Necessities, Cattle Manure Ash (CMA for short) produced after the burning of cow dung is generally treated as garbage abandonment and dumping. the local ecological environment

Abstract

According to the double-doped biomass ash concrete and the manufacturing method thereof, industrial waste fly ash and CMA are doped in the concrete to replace part of cement, heat released by hydration heat of the fly ash is little, hydration heat reaction is reduced, temperature cracks are reduced, the CMA can reduce the heat conductivity coefficient of a base material, the self-heat-preservation function is achieved, and the strength meets the requirement; and the double-doped biomass ash concrete is low in cost, green and environment-friendly, can be applied to concrete with various requirements due to the specific performance, and improves the performance of the concrete.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a double-mixed biomass ash concrete and a manufacturing method thereof. Background technique [0002] Green construction is an engineering construction activity that, in accordance with the requirements of green development, through scientific management and technological innovation, adopts a construction method that is conducive to saving resources, protecting the environment, reducing emissions, improving efficiency, and ensuring quality, so as to realize the harmonious coexistence of man and nature. [0003] At present, on the one hand, the price of cement is rising year by year, and the process of making cement will cause pollution to the environment; on the other hand, in remote Tibetan areas and pastoral areas in the west and north of my country, cow dung is used as fuel after drying, which is the main source of human life. Necessities, Cattle Manure Ash (CMA for ...
