Normal weight of concrete
Web14 de dez. de 2024 · The unit weight of fresh concrete up to 3.6% reduction was observed when 30% of cement was replaced by scoria powder. Furthermore, 40% replacement of cement by scoria reduces the unit weight of fresh concrete by 4.3%. The slight reduction in the unit weight of fresh concrete is due to the lightweight nature of the scoria material. 3.5.
