Various mechanisms have been proposed to explain how organic admixtures affect the hydration of cement clinker compounds. These are reviewed and discussed critically. Complex formation between the organic compounds and aluminate or silicate ions may enhance the initial reactivity of the anhydrous co

On 16 cement pastes made from cements of different clinker composition and containing different amounts and forms of calcium sulfate the composition was determined at the beginning and end of setting. It appears that in cements of "normal" composition the setting is associated mainly with the hydrat

It is known that concentrated solutions of CaCI 2 can cause the breakdown of Portland cement concrete. Recently it has been shown that the severity of CaC12 attack decreases with increasing temperature and above 40Β°C concrete is not affected. From the above observation it was inferred that the break
