BLENZOR-CEMGUARD
ASTM C618 Class-F/ BS EN450
General
Fly Ash is cement like fine grey powder consisting of the finely divided residue resulting from the combustion of Coal at coal-fired power station. It has pozzolanic properties and reacts chemically with calcium hydroxide at ordinary temperature to form insoluble compounds possessing cementitious properties.
Technical Features
In addition to economic and ecological benefits, The use of Fly Ash in concrete improves its workability, reduces segregation, bleeding, heat evolution and permeability, strength, inhibits alkali aggregate reaction and enhances sulphate resistance. The percentage of Fly Ash is usually used as part of the cementitious components in concrete normally from 15 to 25% and can even go up to 30-35% in some applications
Packaging
Fly Ash is offered 1.3 -1.4 MT quality jumbo bags with liner. The jumbo bags conform to GB/T 10454 and EN ISO 21898 standard, with UV proof function and anti- character.
