Description
Technical field
The present invention relates to a kind of cement concrete and preparation method thereof, more particularly to a kind of big density type magnesia oxychloride cement
Concrete and preparation method thereof.
Background technology
Magnesia oxychloride cement is to have invented a kind of binder materials in 1867 by Sweden's scholar's Sorel, it by light-burned MgO,
MgCl2And H2O three reconciles to be formed according to a certain ratio, also referred to as Sorel (Sorel) cement.Magnesia oxychloride cement is a kind of air hardening
Property binder materials, it has fast solidifying, alkalescent and a low-corrosiveness, preferable wearability, prominent caking property, good
Anti-flammability, the advantages that preferable thermal insulation, there is good application prospect, but most of chlorine oxygen magnesium water is used to gently at present
In matter section bar, and the research for being used for the big density type heavy profiles of specific use is then less.Increase magnesia oxychloride cement concrete
Application direction is promoted the use of most important to magnesia oxychloride cement concrete.
The content of the invention
It is an object of the invention to provide a kind of big density type magnesia oxychloride cement concrete and preparation method thereof, present invention system
Standby magnesia oxychloride cement concrete has fast solidifying, and water-tolerant, intensity is high, and the general magnesium cement of density ratio is high a lot
Times, it disclosure satisfy that the demand of many big density heavy profiles.
The purpose of the present invention is achieved through the following technical solutions：
A kind of big density type magnesia oxychloride cement concrete, by weight percentage, its component is the concrete：Magnesia is (living
Property be 73% 96 powder) 6% ~ 10%；Magnesium dichloride hexahydrate 2% ~ 6%；Water 1% ~ 4%；Tertiary sodium phosphate 0.1% ~ 0.3%；Tetraethyl orthosilicate
