WebThe pKa of a strong acid is less than zero. pKa is the negative log base ten of the Ka value, to be precise (acid dissociation constant). It determines an acid’s strength, or how tightly a proton is held by a Bronsted acid. The lower the pKa value, the more powerful the acid and its capacity to transfer protons. WebJul 30, 2024 · During hydration of cement, C3S and C2S react with water and calcium silicate hydrate (C-S-H) is formed along with calcium hydroxide Ca(OH)2. 2 C3S + 6H → C3S2H3 + 3 Ca(OH)2 2 C2S + 4H → C3S2H3 + Ca(OH)2.

Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS2 and structure S=C=S. It is a colorless liquid, which is used as a building block in organic synthesis. It has a pleasant, ether- or chloroform-like odor, but commercial samples are usually yellowish and are typically contaminated with foul-smelling impurities. WebC2S, on the other hand, starts to react typically after 2 weeks and contributes to the long-term strength development [1]. The other main hydration product is Ca(OH)2 which is considered as a weak link in the hydration process since it is the most soluble of all the hydration products and creates durability issues in concrete.
