摘要

The utilization of calcined clay as a pozzolanic material for concrete has received a lot of attention in recent years because of its sustainability and worldwide availability. The performance of concrete made using a locally sourced high kaolinite clay was examined to determine suitability for use in local transportation projects. For this work, the local clay was tested to determine optimal calcining temperature, limestone blend, and sulfate content using isothermal calorimetry (R3 method). The clay was calcined at 600 °C, 700 °C, 800 °C, and 850 °C. The effects of material reactivity as measured by calorimetry were compared to the chloride binding capacity.
