The use of silu00ecco dioxide (si0u00b2) (57) 'the use of silu00eccio dioxide (SiO ~ 2 ~).As aditivopara adhesive mortars industrialized patent invenu00e7u00e3opara silicon dioxide (SiO ~ 2 ~) as a feed additive for argamassacolante,It is a chemical compound that reacts with the hidru00f3xidode calcium, which is the weak, unstable and solu00b7vel, generated in the reau00e7u00e3ode hydration of the cement.Forming the calcium silicate hidratadoque is the strong, stable and insolu00b7vel of cement.This reau00e7u00e3oalem to increase the concentration of calcium silicate hidratadona adhesive mortar inhibits the growth too much of cristaisde calcium hydroxide by filling spaces.Due seupequeno particle size. These two factors promote umaumento pullout resistance resistance aoescorregamento; decrease of fluorescence; cohesion; less sloughing.
