Durability, life cycle cost and life cycle assessment of binary mixtures with fly ash, rice husk ash and concrete demolition waste

Abstract This study analyses, by means of lifespan cost and assessment, the production binary concrete admixtures compound artificial pozzolan demolition waste. Ten formulations were developed, differentiating them in terms mixtures, binder aggregate content, order to verify their potential use columns. The replacements 25% Portland cement for fly ash rice husk ash, 15% 30% natural coarse aggregates results revealed that mixtures with waste showed higher resistance chloride penetration. lowest was achieved highest compressive strength (35 MPa) admixture containing replacement recycled substitution can be classified as most environmentally sustainable one, especially carbon dioxide emissions, among studied.
