Description
Technical field
The present invention relates to building material technical fields, are specifically a kind of water prepared using urban construction dregs rubbish and gneiss
Mud.
Background technology
Cement is a kind of powdery hydraulicity inorganic coagulation material, add water stir after into slurry, can harden in air or
Preferably hardening in water, and can the materials such as sand, stone are cemented together securely.The mixture of early stage lime and volcanic ash with
Modern lime pozzolanic cement is much like, and the concrete made of its cementing rubble, not only intensity is higher after hardening, but also
The erosion of fresh water or brackish water can be resisted.For a long time, cement is widely used in building and builds as a kind of important cementitious material
It builds, the engineerings such as water conservancy, national defence.Cement is divided into portland cement, aluminate cement, sulphur aluminic acid by its main hydraulicity substance title
Salt cement, ferrous aluminate cement, fluoroaluminate cement, phosphate cement and with volcanic ash or latent hydraulicity material and other
Active material is the cement of key component.The production technology of portland-type cement is representative in manufacture of cement, is with stone
Lime stone and clay are primary raw material, through broken, dispensing, it is levigate raw material are made, then feed mature calcined material in cement kiln, then will
Clinker adds proper amount of gypsum is levigate to form.
102815908 B of Chinese invention patent CN disclose a kind of gneiss cement and preparation method thereof, by gneiss,
