Effect of calcining temperature of clas upon their pozzuolanic reaction (1914)
Bow, Warren Edward, Buttonmaker, Mark Adolph · leaf 24
tic pozzuolanes which contain no iron. 4 Bleininger states that colloidal silicic acid on beingbrought in contact with hydrated lim.e will slowly harden to form acement, the substance being a hydraulic calcium silicate.

Of the calcium silicates it is probable that only theCaOSiOg is formed in pozzuolane cements. The ortho-silicate isformed at higher temperatures and the tri-calcium silicate at stillhigher temperatures. The last is the important…
