Determination of heat transfer coefficient of EPS concrete

Cilj ovog rada bio je napraviti uzorak EPS betona približne gustoće 1200 kg/m3 i eksperimentalno prikazati postupak određivanja koeficijenta toplinske provodljivosti. EPS beton je vrsta laganog betona kod kojeg su kao lagani agregat korištene granule ekspandiranog polistirena (EPS). Eksperimentalno određivanje koeficijenta toplinske provodljivosti EPS betona provodilo se metodom mjerenja toplinskog toka. Korišteni su mjerni instrument ALMEMO 2890-9 te senzori za mjerenje protoka topline i temperature. Za analizu izmjerenih podataka korišten je računalni program AMR WinControl. Dobiveni podaci eksperimentalnog mjerenja uspoređeni su sa podacima preuzetim iz literature.The aim of this work was to make a sample of EPS concrete with an approximate density of 1200 kg/m3 and to experimentally present the procedure for determining the coefficient of thermal conductivity. EPS concrete is a type of lightweight concrete in which expanded polystyrene granules (EPS) are used as a lightweight aggregate. Experimental determination of the thermal conductivity coefficient of EPS concrete was performed by the method of heat flow measurement. The ALMEMO 2890-9 measuring instrument and heat and temperature flow sensors were used to measure heat and temperature flow. The computer program AMR WinControl was used to analyze the measured data. The data obtained experimental measurement were compared with the data taken from the literature
