cement hydration reaction

The silica fume particles react with the calcium hydroxide fromcement hydration reactionand form new calcium silicate gels (C-S-H). These gels contribute to the strengthening of concrete (Sohrabi and Karbalaie, 2011 ). Silica fume is also effective in the resistance against chloride penetration.

    After the addition of water, the first reaction occurs between the slag cement and the sodium and potassium alkali hydroxides. The second reaction is with calcium hydroxide (produced from Portland cement hydration) and forms calcium silicate hydrate, which is the same principle hydration product formed during Portland cement hydration. The use of slag cement has potential to reduce the peak …

    What is the heat of hydration in concrete and how is it

    Mar 22, 2017· Cement hydration reaction (reaction of cement with water) is an exothermic reaction. Thus a lot of heat is liberated and this heat that is released is called the heat of hydration. Liberation of a large amount of heat results in cracking of concrete structures. Such phenomena can be seen in mass concrete projects such as in the construction of dams.

    In its simplest form,concreteis a mixture of paste and aggregates, or rocks. The paste, composed of portlandcementand water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemicalreactioncalledhydration, the paste hardens and gains strength to form the rock-like mass known asconcrete.
