Description

technical field

[0001] The invention belongs to the technical field of building materials, and relates to a slag additive and its preparation method and application. Background technique

[0002] With the development of my country's economy, energy and environmental issues have gradually become the focus of attention. my country is a big country in the building materials industry, especially the cement and concrete industries have a great impact on resources and the environment. According to statistics, for the production of 1 ton of cement, about 1.2 tons of limestone and 150 kg of standard coal are consumed, and about 0.87 tons of CO2 are emitted at the same time. 2 . Globally, CO emissions from the cement industry into the atmosphere 2 accounting for about 7% of total emissions. Therefore, while ensuring the steady development of economic construction, attention should be paid to reducing energy consumption and protecting the environment in the building materials indu...
