Szukana fraza: [Abstract = "Test results showed that Th e electrical resistivity, water absorption, and crushing strength of both aggregates varied with time. These values were found to be stabilised after approximately after 14 days. The electrical resistivity for aggregates containing Marconite were found to be 39.2 \[omega\].m, far lower than 12700 \[omega\].m obtained for mortar\-based aggregates. Similarly, the water absorption for Marconite aggregates were greater compared to mortar aggregates."]
