  • Publication number: 20240383810
    Abstract: A compressive strength improving, water uptake reducing additive composition comprising: an alkyl silane or its hydrolysate or mixture thereof comprising a silicon resin comprising units of the formula (Ia) thereof along with an additive composition and an antifoam composition; wherein the composition is used before, or during the grinding process in the cement plant not only reduces the energy consumption during grinding but also eliminates any further addition of the hydrophobic additive material to render hydrophobicity along with the improved compressive strength of the constructed structure. Such hydrophobicity along with the improved compressive strength of the constructed structure is achieved even when the composition is used after the grinding process.

  • Patent number: 10766825
    Abstract: A composition comprising a self-dispersible mixture additive composition comprising a alkylalkoxysilane of formula (RO)4-nSiR?n, or its hydrolysate or mixture thereof, where, R is same or different C1-C20, R? is same or different C1-C20; mixture of non-ionic emulsifier of HLB value between 8 and 20. The self-dispersible mixture additive composition is obtained by mixing the alkyltrialkoxysilane with a mixture of non-ionic emulsifier. The emulsion of the self-dispersible mixture additive composition is formed by mixing appropriate amount of an aqueous solvent to the self-dispersible mixture additive composition, and addition of thus formed emulsion to a porous product preferably dry cement to render uniform and long lasting hydrophobic property of the final product made of the porous product.
