WebbCement is the most produced material in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, providing a cohesive strength that rapidly increases during setting. Understanding how such cohesion emerges is a major obstacle to advances in cement science and technology. Here, we combine … Webb7 mars 2024 · Consistency acts as an indicator for the fluidity properties of a certain concrete mixture. Slump test is the way of measuring the consistency of concrete . Concrete with high slump value is very fluid while stiff concrete has a low slump value. Best workability is achieved at medium consistency i.e. slump ranges between 75 to 150 …
