Abstrakty

Przedstawiono kompleksowe badania doświadczalne właściwości betonu napowietrzonego, zawierającego zmielone odpady z cegieł, jako dodatek mineralny zastępujący cement portlandzki. Stwierdzono, że w przeciwieństwie do wielu wcześniejszych badań różnych rodzajów betonów wykonanych z cementu portlandzkiego z dodatkiem proszków ceramicznych, graniczny dodatek zmielonych cegieł jest znacznie większy niż często podawane 20% masy spoiwa. W przypadku większości zastosowań beton napowietrzony może być wytwarzany z cementów wieloskładnikowych zawierających 60% zmielonych odpadów z cegieł, bez pogorszenia jego właściwości inżynierskich.

The complex experimental tests of the air-entrained concrete (AEC) properties, containing waste brick powder as supplementary cementing material are presented. Contrary to many previous studies, concerning of different types of concrete based on the Portland cement with ceramic powders as mineral addition, the limit for the effective use of brick powder is found to be much higher than the often reported 20% of mass of the binder. For a majority of practical applications, the designed AEC mix allows using blended cements containing up to 60% of fine red-brick ceramics without any significant worsening of the most engineering properties.
