Portland cement and pure slag paste were studied both during early hydration [4, 5], and in aged . 2 samples [6, 7]. These studies were able to conclude that the addition of blastfurnace slag reduces the Ca:Si ratio, increases the Al:Ca ratio, changes a strongly linear microstructural morphology to a fine foillike morphology. The finer morpohology has been used to explain reduced diffusion ...

composition of oxides in GGBS is similar to that of Portland cement but the proportion varies. This paper deals with the use of the blast furnace slag powder as a partial replacement of OPC and its effect on strength of cement concrete mix 2 LITERATURE REVIEW Throughout the long history of the iron and steel industries, ways have been sought to make effective use of these slag, but their ...
Cement Based Composites (CEBACOM) ... inclusions on the mechanical properties and durability of geopolymerMPCM mortars based on granulated blast furnace slag (GBFS) and to compare them with Portland cementMPCM based mortars. The results show that the addition of two proportions of metakaolin is able to compensate well for the loss of mechanical strength associated with the addition .
Portland cement Xray diffraction abstract Processes of structure formation taking place in the interfacial transition zone ''cement paste – aggregate'' have been studied on a variety of cement model systems. The results of this study suggest that, depending upon the contents of components capable of actively interacting with alkalis in the presence of reactive SiO 2 in the cement ...
A blended binder system (10 % portland cement, 45 % fly ash, and 45 % slag) is characterized as part of a broader study of its longterm effectiveness in stabilizing treated salt waste at the Savannah River Site. The binder system is reproduced in the laboratory using a simulated salt solution, and the hydrated phases are identified and quantified out through one year of hydration. The phases ...

10. Slag Cement. Portland Slag Cement is a hydraulic cement that is manufactured by grinding burnt furnace slag to suitable fineness and mixed with ordinary portland cement in a particular ratio. It seems to be the colour of blackish grey. The price of slag cement is lower than the OPC cement. It is not suitable for standard RCC structure ...

Answer (1 of 3): Composite Cement is covered under IS: and presents a good opportunity to produce high strength concrete which is highly durable. Composite cement is a mixture of high quality clinker (IS:), fly ash (IS:3812 (Part 1) 2013), granulated slag (IS:) an...
This cement was first used commercially in Germany in the 1860s, and it was such a success that engineers in 1889 decided to build the Paris underground metro using slaglime cement. Slag cement blended with Portland cement first appeared in Germany in 1892, and four years later was introduced to workers in the United States.

Portland Slag Cement, commonly known as PSC, is blended cement. Slag is, essentially, a nonmetallic product comprising of more than 90% glass with silies and aluminosilies of lime. At JSW Cement, we use superior quality slag produced at our steel manufacturing plant, conforming to IS: 12089 standards for producing PSC. It is created with a combination of upto 45 50%
· There are very few studies examining how the rheology of geopolymers or Portland cement composites is affected by MPCM ... The slag, fly ash, and Portland cement have quite wide size distributions, where most of the particles are smaller than the microcapsules (Figure 2). Fly ash particles are mostly spherical (Figure 1E), while the slag has an irregular shape with sharp edges .
