Abstract : Self-Compacting Lightweight Concrete (SCLC) has gained significant attention as an advanced construction material for high-rise buildings due to its ability to combine reduced density with superior workability. The researchers conducted a study to test the engineering properties of SCLC material while they worked to enhance both its fresh state and hardened state properties which support structural uses. The use of lightweight aggregates in concrete construction provides essential benefits because it reduces concrete weight, which results in decreased dead loads that improve structural performance for tall buildings. The fresh properties of SCLC were assessed through standard tests which measured its flowability and passing ability and segregation resistance. The results show that SCLC mixtures which have been correctly designed can achieve self-compacting performance without needing external vibration because they distribute material evenly through areas with high reinforcement density. The research measured essential properties of the hardened material through tests which examined its compressive strength and tensile strength and elastic modulus and density. The resultsshow that SCLC reachessufficient load-bearing capacity while its unit weight remains much lighter than traditional concrete. The use of supplementary cementitious materials together with high-range water-reducing admixtures enhance durability through its ability to decrease permeability while providing better protection against environmental damage. The study concludes that SCLC offers a high strength-to-weight ratio and improved constructability, which makes it a sustainable building material for high-rise construction. The system provides construction benefits through foundation weight reduction and better earthquake protection and shorter building time, which meet current engineering standards.
