Expanding additives

GM-EA Expanding agent

GM EA is expanding agent, which can be used to formulate expanding cement slurries. The GM EA reacts with the alkalis in the cement slurry to produce small bubbles of hydrogen gas. The reaction and thus the degree of expansion are dependent on several factors including pressure, temperature, particle size and concentration of the GM EA and special coating, which allows you to delay the start of the reaction. This product does not negative effect on final strength properties of cement stone. Typical application is in the range of 0.05 to 0.50% by weight of cement. For more information please see technical data sheet.

 

EXPOX Expanding agent

EXP OX is expanding agent which can be used to formulate expanding cement slurries. The expansion mechanism is the growth of the crystals within the solid cement matrix. These crystals have a greater bulk volume than the original solids from which they form, and cause a wedging action because of the internal pressure of crystalline growth, forcing the solid matrix apart. Typical application is in the range of 4 to 12% by weight of cement.
