W pracy wykorzystano metodę ultradźwiękową do badania mechanizmu wzajemnego oddziaływania szkieł nawozowych i roztworów kwasu solnego lub cytrynowego symulujących warunki naturalnego środowiska glebowego. Przebieg biodegradacji szkła badano poprzez obserwacje mikroskopowe zmian jego powierzchni, pomiary zmian masy szkła oraz prędkości rozchodzących się w nim podłużnych fal ultradźwiękowych. W początkowym...
The influence of different types of deflocculants and their combinations upon structural formation during hardening of MCC-type refractory castable with mulite aggregates was analyzed using an ultrasonic method. It was established that the structure of castable formed in two stages when the sodium tripolyphosphate deflocculant was used. In the first stage the speed of ultrasound reached approximately...
