Description
Technical field
The invention belongs to cementitious material field, especially a kind of build concrete cementitious material preparation method.
Background technique
Concrete gel material is mainly cement at present, and energy consumption and carbon emission are all very huge in cement production process,
The technology that cement prepares concrete material can be substituted by, which finding, has positive effect to the environmental protection and sustainability that improve concrete.
Since China's energy resource structure is based on coal electricity, a large amount of by-products " flyash " can be generated after coal-fired power plant's coal dust firing, at present
China's flyash volume of cargo in storage is up to more than 400,000,000 tons, it has also become the solid pollution source of Largest In China.Flyash and cement fineness are close,
Due to burnt again cool down after it is with higher chemistry in can and pozzolanic activity, part replace cement after, can be with cement water
Change the calcium hydroxide reaction generated, generates the gum material with some strength, therefore flyash is widely used in cement at present
With concrete as admixture.However ratio of the flyash in concrete gel material is below 30% under normal circumstances, continues
Increasing the volume of flyash, especially volume is more than that will cause concrete early stage and later strength significant decrease after 50%, cannot
Meet construction demand.
