Web→ CSH + Silicofluoric Gel Another type of silicate-based liquid densifier is a fluorosilicate solution (also called silicofluoride), such as Euclid Chemical’s Surfhard. It, too, reacts with excess calcium hydroxide in the concrete surface to form CSH. However, fluorosilicates also react with calcium carbonate, CaCO 3 WebMar 14, 2016 · Cement hydration products. The main products of cement hydration reactions are calcium silicate hydrate (CSH), calcium hydroxide (CH), and the AFt and AFm phases. The AFt and AFm phases found in hydrated cement are compounds of C3A, anhydrite and water. The most common AFt phase is ettringite and the most prevalent …
WebTo optimize the chemical structure of the silicon organic compounds, it is important to know how they are connected to the surface of the CSH-Gel. Three types of bonding between silane/siloxane and the surface are con-ceivable: chemical bonding, adsorption by van-der-Waals forces and hydro-gen bonds [9]. WebChemical reactions during hydration When water is added to cement, the following series of reactions occur: ... CSH - 50 to 60% Calcium hydroxide (lime) - 20 to 25% Voids - 5 to 6% (in the form of capillary voids and entrapped and entrained air) Conclusion It can therefore be seen that each of the compounds in cement has a role to play in the ...
