Abstract
The current invention comprises the MANUFACTURING PROCESS AND COMPOSITION OF CONCRETE ADDITIVE with the purpose of adding hydrophobic and waterproofing properties to concrete, as well as improving its mechanical properties. The process involves two phases of component mixing/heating, and the additive composition comprises mortar, cement, calcium carbonate, active microsilica, calcium stearate, and graphite.
Claims38
A concrete additive composition comprising calcium carbonate, a pore blocker, a hydrophobic compound, and comprising in its composition:
- a) AC (adhesive cement) mortar,
- b) Portland cement, and
- c) a separately produced formulation that is composed of Portland cement, hydrophobic compound and graphite.
A method of manufacturing a concrete additive, comprising:
- separately producing a formulation composed of:
- Portland cement, hydrophobic compound and graphite;
- heating the formulation from 70° C. to 150° C., homogenized properly in a grinder;
- and
- after producing the formulation, forming a second mixture while heating, at a temperature of 70° C. to 170°, the second mixture having a composition comprising:
- Portland cement, AC (adhesive cement) mortar, calcium carbonate, pore blocker, hydrophobic compound, and the formulation, to generate a final product.
