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.
can also be achieved by using Type GU cement w ith an appropriate amount of fly ash or slag added at the ready-mixed concrete batch plant. Table 2.1 Portland
Slag cement does not contain carbon and does not cause instability in the entrained air content. Time of Set. Time of initial set is influenced by the use of slag cement and fly ash. Concrete made with slag cement can have faster set times than concrete made with fly ash (Figure 2). Pumpability and Finishability. Pumpability with 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. To check for suppliers in your area, use the SCA’s slag cement locator.
2019-10-1 The present work analyses the basic research trends on the use of fly ash and granulated slag in cement and concrete and other binding composites in 2015–2018. Attention was also given to the properties and possibilities of using fly ash in cement composites, as product from other coal combustion techniques as well as ashes obtained from the
2019-3-2 Results of this study indicated that the 50% fly ash replacement of Portland cement increased the rupture modulus of the recycled concrete. Conversely, a mixture with over 50% cement replacement by either fly ash or slag or a combination of both exhibited detrimental effect on the compressive strength, rupture modulus, and drying shrinkage.
2014-9-29 utilization of fly ash in concrete began (for example, USBR 1948) follow-ing the pioneering research conducted at the University of California, Berkeley (Davis 1937).The last 50 years has seen the use of fly ash in concrete grow dramatically with close to 15 million tons used in con-crete, concrete products and grouts in the U.S. in 2005 (ACAA
2016-9-28 use of Type II additions as fly ash and slag in concrete. The workshop was organised by Bård Pedersen and Claus K. Larsen from Norwegian Public Roads Administration & Dirch H.

2021-9-20 Fly Ash. Fly Ash is a by product of power generation that not only offers environmental benefit through the reuse of waste materials, but also provides enhanced benefits when added to concrete. Fly Ash can be combined with other materials to produce high quality and economical results in concrete such as pre-mix, pavements, sub-bases and dams.
2021-6-28 The amount of the AFm phase is lower in the high-volume slag cement incorporating CFBC fly ash as compared to the CC mix. These findings are in good agreement with previous work, which stated that the use of CFBC fly ash with SCMs nullifies the formation of ettringite and results in the uncontrollable expansion of the specimen .
