Clay brick; SCBA; BMC; FTIR; XRD
Materials and methods
The sugarcane bagasse ash was collected from a sugarcane plant located in Tamilnadu, India. The brick making clay (BMC) was collected from the river bed of Kaveri, Tamilnadu. Selected mixtures (BMC + SCBA) containing 0, 5, 10, 15 and 20 wt.% of waste were prepared Table 1. Using the above mixture proportions five batches of samples were molded in a rectangular shape with dimension 90 × 25 × 30 mm. The prepared samples were dried at room temperature for 10 days and then fired at various temperatures in the range of 800–1100 °C in steps of 100 °C with a soaking time of 1 h till the maximum temperature is attained. Cooling occurred by natural convection after competitive release was turned off. The chemical composition of BMC and SCBA was carried out on the XRF (PW 1400 Philips). The green samples and the fired specimens were subjected to FTIR and XRD techniques.
