Özet
We used expanded clay (EC) and cement, fly ash (FA), and pine tree resin as binders instead of conventional aggregate to produce low-density construction material. The EC ratios were 10 %, 20 %, 30 %, 40 %, and 50 %. The FA ratios were 10 %, 20 %, and 30 %. The pine tree resin was 1% of the total volume. The samples were dried for 28 days at room temperature, and then measurements were carried out. We produced 48 samples divided into four groups: no additive (Group 1), FA added (Group 2), resin added (Group 3), and FA + resin added (Group 4). Thermal and mechanical tests were performed to determine where in buildings the low-density construction material could be used. When EC rate increased from 0 % to 50 %, the thermal conductivity coefficient and compressive strength decreased by 55.4 % and 35.1 % only with the effect of the EC aggregate; 13.0–13.69 % with the effect of FA only, 8.4–15.6 % and iii) 17.6–21.86 % and 58.6?17.13% by the effect of FA & resin. The lowest thermal conductivity coefficient was 0.168 W/mK. The highest compressive strength was 24.68 MPa. All samples had a water absorption rate lower than 30 %.
