W pracy opisano badania wpływu ultradźwięków na wytrzymałość zaczynów cementowych z różnym dodatkiem syntetycznego zeolitu. Przeprowadzone doświadczenia wykazały, że poddanie działaniu ultradźwięków świeżych zaczynów z cementu, bez i z dodatkiem 5% 10% oraz 15% syntetycznego zeolitu, zastępującego cement, zwiększa ich wytrzymałość po 3 dniach twardnienia. Zastosowanie tego promieniowania nie jest efektywne w przypadku próbek, które dojrzewały przez 28 dni, z wyjątkiem zaczynów bez i z dodatkiem 5% zeolitu. Wytrzymałość tych zaczynów także wzrasta po 28 dniach, gdy zostały poddane działaniu ultradźwięków.

In the paper the sonication treatment effect on the strength of the cement paste was presented. The tests have shown that the sonication applied to the fresh cement paste, without and with 5%, 10% and 15% of synthetic zeolite addition replacing cement, is increasing the strength after 3 days of hardening. This treatment is not effective in the case of the samples strength after 28 days of curing, except for the pastes without and with 5% of zeolite addition. The strength of these samples are also increasing after sonication of the pastes.
