    Good day,

    I hope you are all well. My name is Kelvin Marumba, a civil engineer, currently working as the operations manager for a ready mix concrete company in Zimbabwe called Fourways Concrete. The competition in the market between ready mix concrete companies over the past year has become very steep and slowly it is turning into a price war. What methods can be used to make my concrete more cost effective and still maintain the good quality ? I have been using the DOE method for my mix designs and because of inconsistence with the riversand here, i resorted to using a combination of quarry dust and pit sand as a substitute. I tried to look at using fly ash in the mix but we do not have enough capacity of the fly ash to sustain our operations so i am seeking assistance with any other ways in which i can cut my costs by creating the most efficient mix design using the less costly material and maintaining good quality. Thank you
