Sorel cements

In special cases, for very deep bore holes cementing, the lime with quartz sand mixtures, metallurgical slags, as well as the dicalcium silicate with sand mixtures can be used [169], In Russia the slag activated with sodium compounds is used 

Sorel cement does not have hydraulic properties, however, because of its special properties it is worthwhile to pay an attention to this material. Primarily it is single out for high strength, high elasticity modulus, abrasion resistance and refractoriness 

Sorel cement, more precisely the Sorel cement paste, is produced by mixing MgO with magnesium chloride solution  

The phase formed in reaction (9.17) is called as 5 1 8 or 5 and can be written using the following formula 

The latter one is determined as 3 1 8 or 3. They both dissolve in water.

So-called sorel cement" is not a cement in the true sense of the word. Mixtures of caustic burnt magnesite (reactive MgO, produced by heating magnesium carbonate just above its decomposition temperature) and magnesium salts harden into a stone-like mass.

Cement is a powder, which mixed with water forms plastic mass, easy to shape (paste), setting with time and hardening gradually with strength increase. In marty standards the more exact Portland cement definitions were introduced. It is necessary because the name of cement is given to other binding materials, for example to anhydrite or magnesium oxychloride (the last is called Sorel cement). 

As in the case of Portland cement the hydration of Sorel cements proceed simultaneously. The formation of low soluble A phase is advantageous, because it contributes to the improved durability of the Sorel cement paste. The soluble phosphates added to the Sorel cement paste raise the resistance to water, due to the insoluble complexes formation. Phosphate is adsorbed on the sirrface of phase 5 and the layer...

Magnesium oxychloride cement, also called Sorel cement, is obtained by mixing powdered magnesium oxide (calcined magnesia, MgO) with a concentrated solution of magnesimn chloride (MgClj). 

Even faster setting and strength gain can be achieved by direct acid-base reactions. For example, magnesium chloride and magnesium oxide (Sorel cement) react very rapidly in water to form...

For centuries, bonding has proven successfid as a joining technology in civil construction. Actually, any mortar, as it is used today, is an adhesive. Binders that only harden under air ( air binding such as plaster, sorel cement, anhydrite, magnesite, and white lime) are referred to as non-hydraulic binders, while hme and especially cement are hydraulic binders because setting can be done under water.
