Abstract
The present invention relates to building material technical field, particularly relating to a kind of rapid-curing cutback cement, described rapid-curing cutback cement is by the component of following parts by weight: clinker 40 50 parts, anhydrous gypsum 15 25 parts, industrial residue 20 30 parts, little granule river sand 10 15 parts, bulky grain river sand 20 30 parts, 16 30 parts of configurations of powdered coal cinder form.The rapid-curing cutback cement of the present invention, has certain mobility, and setting time is short, and intensity is high, color even, environmental protection；Raw materials for production low cost, production technology is simple, is suitable for industrialized production, can be applicable.
Description
Technical field
The present invention relates to technical field of buildings, particularly relate to a kind of rapid-curing cutback cement.
Background technology
Cement is powdery hydraulicity inorganic coagulation material.Add water and after stirring, become slurry, can harden in atmosphere or at water
In preferably harden, and can be the most cemented together for the material such as sand, stone.The concrete made with cementing rubble, firmly
After change, not only intensity is higher, and can also resist the erosion of fresh water or brackish water.For a long time, it is as a kind of important gelling
Material, is widely used in the engineerings such as civil construction, water conservancy, national defence.The accelerated development in city brings white elephant to environment,
The consumption of cement is increasing, and factory is a lot, and slag then becomes a kind of material in short supply, and cement plant is not often due to slag is for
Should ask and stop production.The kind of cement is a lot, general-purpose cement, cement special and characteristic cement three can be divided into big by its purposes and performance
Class.But cement the most on the market, in use, rate of drying is slow, affects the progress of engineering to a certain extent.
Summary of the invention
The present invention is directed to the problem that prior art exists, it is provided that a kind of rapid-curing cutback cement, solve in prior art and exist
The problems referred to above.The rapid-curing cutback cement of the present invention, has certain mobility, and setting time is short, and intensity is high, color even, environmental protection
Etc. feature；Raw materials for production low cost, production technology is simple, is suitable for industrialized production, can be applicable.
For solving above-mentioned technical problem, the technical solution used in the present invention is achieved in that
A kind of rapid-curing cutback cement, by the component of following parts by weight:
Clinker 40-50 part, anhydrous gypsum 15-25 part, industrial residue 20-30 part, little granule river sand 10-15 part, bulky grain
River sand 20-30 part, the configuration of powdered coal cinder 16-30 part form.
Further, this rapid-curing cutback cement is made up of the component of following parts by weight:
Clinker 45 parts, anhydrous gypsum 20 parts, industrial residue 25 parts, little granule river sand 12.5 parts, bulky grain river sand 25 parts, powder
Coal ash 25 parts.
Further, this rapid-curing cutback cement is made up of the component of following parts by weight:
Clinker 50 parts, anhydrous gypsum 25 parts, industrial residue 30 parts, little granule river sand 15 parts, bulky grain river sand 30 parts, fine coal
Lime-ash 30 parts.
Further, one or both the mixture during described industrial residue is slag and gangue.
The present invention has the benefit that
The features such as the rapid-curing cutback cement of the present invention, has certain mobility, and setting time is short, and intensity is high, color even, environmental protection；
Raw materials for production low cost, production technology is simple, is suitable for industrialized production, can be applicable.
