A study of high-performance slag-based composite admixtures

Effect of GGBFS on Compressive Strength and Durability of Concrete

“…However, producing one ton of OPC will have about 1510 kWh consumed and 900kg of CO 2 emissions [1]. Facing the cement and concrete development process, reducing greenhouse gases and the consumption of natural resources has become an important issue [2,3]. In order to reduce the cement content in concrete, the increased use of concrete combining large amounts of industrial by-products is expected.…”

Pre-packed alkali activated cement-free mortars for repair of existing masonry buildings and concrete structures

“…This phenomenon is due to the different porosity of slag-based pastes compared to traditional cement pastes. Indeed, alkali-activated slag pastes have a much higher proportion of pore size within mesopore region than OPC pastes [28,29]. Further, the radius of pore where the meniscus forms is smaller for AAS than Portland-based pastes, in accordance with the theory that capillary tensile forces set up during drying is a very significant factor for the drying shrinkages of alkali-activated slag materials [30].…”

Binders alternative to Portland cement and waste management for sustainable construction—part 1

“…The radius of pores where the meniscus forms seems to be a key parameter for shrinkage. [243][244][245] Researchers note that, by increasing the water/binder, there is a growth in shrinkage due to two factors: the large amount of water able to evaporate, and the increase in binder paste/aggregates. 246 In addition, it is possible to note that shrinkage is also influenced by type and contents of alkaline activators.…”
