原始语种摘要: Managing the waste resulting from precast concrete activities is a challenge for the industry. This paper addresses the problem by providing potential applications involving the use of recycled crushed concrete as aggregates. For precast applications, the main properties of the material should be high reactivity at an early age (1 day), optimal performance at 28 days, and enhanced long-term durability. This study presents a systematic comparison between the properties of a control self-compacting concrete (SCC-0%) blended only with natural aggregates (NA) and SCC blended with 10% recycled aggregate (RA) as a partial replacement for NA (SCC-10%). For steam-cured SCC for precast use, fresh state properties (slump and segregation resistance), mechanical compressive strength and durability...
