Thermal and Compressive Strength Properties of Sepiolite Substituted Autoclaved Aerated Concrete

Aerated concrete is a lightweight concrete which has porous structure. in this study, effects of usage of sepioliteas a raw material instead of quartzite on the thermal and compressive strength properties of aerated concrete were investigated.g2/04 class aerated concrete, which has been commercially produced as a wall component, has been focused. aerated concrete samples have been prepared by substitution of sepiolite instead of quartzite in %5, %10, %15, %20 and %25. sepiolite has been provided from eskişehir mine field. after 4 hours cure at 60°c, samples moved to treat in autoklave in the temperature of 180°c and pressure at 11 bar for 6.5 hours. thermal conductivity and compressive strength properties of samples were determined. as a result, increasing the rate of sepiolite in aerated concrete decreases the compressive strength and increases the thermal conductivity.
