Kefid has been a main supplier of slag grinding processing equipment for several Steel Company in China, We also carried out a slag grinding production project with large number of big domestic Steel Companies. The main product is vertical mill system, which breaks the "bottleneck" of big volume concrete cracking technology because the small investment,WHY USE FLY ASH AND SLAG IN CONCRETE? - Bay-Lynx,,With cement being the costliest ingredient, substituting fly ash or slag can help maintain a stronger mix at a lower cost. Fly ash and Slag will typically be 18% cheaper than Portland cement. When a mix includes 20% fly ash, this will provide savings of 3.5% in cost. The advantage of slag is its ability to substitute more of cement. Giving savings of up to 9% in cement cost with a 50% slag to cementThe use of steelmaking slags and fly ash in structural,,01/03/2016· In this context, the study looks at the preparation of these mortars with steelmaking slags (electric arc furnace slag, ladle furnace slag) in partial substitution of conventional aggregates, and as supplementary cementing materials, and the use of Portland cement that includes a notable proportion of fly-ash. A detailed examination of the characteristics of eight mortar mixes is described,Slag cement with fly ash - Slag Cement Association,The ternary diagram, shown in Figure 1 shows that slag cement is more closely related to portland cement than fly ash. This is one reason why slag cement can be used in much larger amounts. Both are used as a replacement for a portion of the portland cement. Slag cement replaces as much as 50 percent in normal concrete (and up to 80 percent in special applications such as mass concrete). Fly ashThe Difference in Slag Cement and Fly Ash - Slag Cement,Once a good relationship with a supplier is established, slag cement can be used at a higher percentage than fly ash. In most cases, slag cement can be used as a 30-50% replacement to portland cement, reducing the carbon impact of the concrete.
