Engineering performance of metakaolin based concrete

The sustainable development goal (SDG) 14 of the 2030 Agenda for Sustainable Development aims at protection, conservation, and management coastal ecosystems resources, including by strengthening their resilience, to avoid significant adverse impacts. Coastal/marine structures are exposed aggressive environmental conditions, such as chloride laden environment. Deterioration reinforced concrete located in a coastal/marine setting can influence safety, economic sustainability aspects society. Hence, there is an increased need materials with ability reduce effects attack concrete. This experimental study investigate engineering properties metakaolin (MK) based attack. investigation was conducted different w/b ratios 0.54–0.61. MK, utilised cementitious material, varied from 0 20% increment 5% ages 7 56 days were considered. above-mentioned parameters on various workability, compressive flexural strength, durability, resistance microstructure samples investigated. From favourable strength durability results that observed during (optimum 49.8 MPa 10% MK optimum 8.35 MK), it be concluded feasible supplementary material combatting structures. obtained results, combination lack carbon dioxide CO2 released manufacturing process, further highlights positive improving serviceability states
