composite cement vs slag cement

The usual pattern of cement hydration involves rapid reactions of cement components exposed on the fractured surfaces of the individual ground clinker grains. 0 ثبت شکایت | %PDF-1.5 %���� The Portland slag cement is one such cement, which uses blast furnace slag in the production of cement. Composite cements, based on ternary blends of portland cement, fly ash, and ground granulated blast-furnace slag, may be produced, in agreement with the European Standard EN 197/1(1), with a slag + fly ash content up to 60% (CEM V/A) or 80% by mass (CEM V/B). (I have had many houses built with fiber cement and have never seen any delaminating in 8 years. Second, blast furnace slag cement has a lower pH than Portland cement, which reduces the alkali silica reaction (a higher pH means that more hydroxide, which is needed to break down the silica networks, is present). For ready-mix producers and concrete product producers, CEMSlag TM is an eco-friendly, durable, cost-effective product that enhances the quality of your concrete. Slag is produced during the iron-manufacturing process. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. 722 0 obj <>/Filter/FlateDecode/ID[<12F36AAA227EDA4FAA063998C30D1C13><1092848867FCF440A4C2717825E40DBD>]/Index[709 20]/Info 708 0 R/Length 72/Prev 92705/Root 710 0 R/Size 729/Type/XRef/W[1 2 1]>>stream Slag and fly ash complement each other in a composite cement.
