Durability of concrete using marble mining waste
The aim of the study was to study behavior of concrete containing marble mining waste under aggressive environment. Waste from marble mining and processing industries was used in concrete as coarse aggregate in combination with conventional coarse aggregate. The particle packing density approach was followed to design the concrete mix and 75% conventional coarse aggregate was replaced by aggregate obtained by crushing waste from marble mining waste. The water-cement ratio was fixed 0.45 for all the mixes. Properties of concrete under aggressive environment such as chloride ion penetration, resistance to sulphates were evaluated. The test results revealed that, resistance to chloride ion penetration and sulphate attack increased as compared to control concrete. Overall the results supported by microstructure analysis indicate that there is no significant adverse effect on the use of marble waste as a coarse aggregate on the durability properties of concrete. The results of fire study reveal that, concrete with marble waste performs better than control concrete up to a temperature of 800 ºC.
