Thermal and mechanical analysis of thermal power plant ashes, cement and resin composites

Öz

This study used thermal power plant fly ash (FA) and bottom ash (BA) as fill materials and investigated the thermal properties of composites made of cement and pine tree resin binders. For each ash group, 36 samples were prepared by adding 50% cement and 1% to 2% resin as binders. i) FA samples had 23.18%, 22.99%, and 77.01% lower density, thermal conductivity, and compressive strength than BA samples, respectively. FA samples had 9.42% higher porosity than BA samples. ii) FA (0.177 W/mK) and BA (0.221 W/mK) samples with resin and cement had the lowest heat transfer coefficients. iii) FA (14.46 MPa) and BA (36.96 MPa) samples (resin + cement binder) had the highest compressive strength values.
