文摘

Biomass fly ashes and bottom ashes can be used in the production of dry cast concrete. % of BFA as cement replacement DCC to meet the overall performance requirements. The use of BBA tends to decrease mechanical performance due to compactness losses. Combining BFA and BBA in DCC lead to lower water absorption values than required.
