Limestone is widely used as the main ingredient in cement and mortar, and as an aggregate in concrete and asphalt for building roads. It iis also used as a soil conditioner and is the raw material for making quick lime and slaked lime. During mining and processing operations, limestone composition must be monitored and controlled to ensure proper quality and characteristics are achieved for a variety of products. This application note demonstrates the measurement of carbonates and major oxides in high calcium limestone by EDXRF using empirical calibration.
