W pracy zbadano wpływ dodatku sepiolitu, zastępującego piasek kwarcowy w autoklawizowanym betonie komórkowym (ABK) na właściwości tego kompozytu cementowego. Doświadczenia wykazały, że dodatek sepiolitu większy od 10% zmniejsza wytrzymałość na ściskanie ABK i zwiększa zawartość wilgoci, już przy dodatku 5%. Także gęstość suchych próbek ulega szybkiemu zmniejszeniu przy wzroście tego dodatku do 15%, a od 20% do 25% już wolniej. Natomiast przewodność cieplna zmniejsza się znacznie z poziomu 0,105 do 0,088 już w przypadku dodatku sepiolitu, wynoszącej 10%. Ten poziom dodatku sepiolitu, zastępującego piasek kwarcowy, można uznać za najlepszy.

In the work the effect of sepiolite addition, replacing quartz sand in the autoclaved cellular concrete (ACC), on the properties of this cement composite was examined. It was found that sepiolite content higher than 10% is decreasing compressive strength of ACC and increasing its moisture content, already at addition of 5%. Also dry density is decreasing quickly up to 15% and from 20% to 25% only slowly. However, thermal conductivity is decreasing substantially from 0.105 to 0.088 for 10% sepiolite addition. 10% of sepiolite is the best level of replacement of quartz sand in ACC.
