Thermal Conductivity and Strength Properties of Soil-Based Lime Adobe Stabilized with Pottery Burnt Hull Ash

Abstract:

This work studies the possibility to produce the new novel brick by mixing between the local soil, local lime and burnt hull ash which is the waste in the earthenware industry. All materials conducted in this work are found in Ratchaburi province located in the western of Thailand. The chemical and mechanical properties are studied including the thermal conductivity will be determined. Varying burnt hull ash (BHA) contents are added into the combination and compared properties with the soil cement brick (RCB) at the same percentage weight. Results show that the compressive strength and flexural strength of soil brick mixed with 10% constant lime and varying burnt hull ash contents (CLBA) shows the maximum values at BHA of 25% by weight at water to powder ratio of 0.4225 and the thermal conductivity of CLBA is lower than that of SCB given as 43.98%.
