“…The modifiers, which are included in the composition of the developed additive, due to the alleged reaction activity, are supposed to react with Са(ОН)2 or with tobermorite-like hydrosilicates like CSH(I) which are formed in hydration of calcium silicates included in Portland cement. In this, new phases may be formed represented by low-basic hydrosilicates having fibrous structure which has a reinforcing effect on a forming structure of a hardening material, which increases bending tensile strength [1,2] and, as a result, crack resistance of the material. Scientific studies [3,4] confirm a good compatibility of silica sol, consisting of nanodispersions SiO2•nH2O, and polycarboxylate polymers [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”
