Performance of wood bottom ash in cement-based ...

Wood bottom ash (WBA) is a type of wood waste ash produced as a by-product from the incineration or combustion from wood-fired power plants, pulp and paper and wood-burning industrial facilities. It is the fraternal twin of the most common and popular fly-ash which is obtained from the same process.
