a dry fly ash pile at a large coal-fired power plant. Activities monitored on the dry stack included hauling, dumping, and grading. In addition, an unpaved road exists along the base of the dry stack on top of a berm to stabilize the stack. This road is a source of vehicle-generated fugitive dust, and

ABSTRACT In the paper, an artificial neural network (ANN) model is proposed to predict the compressive strength of concrete. For developing the ANN model the data bank on concrete compressive strength has been taken from the experiments conducted in the laboratory under standard conditions. The data set is of two types; in one dataset 15% cement is replaced with fly ash and the …
