Abstract :

Ultra-high strength concrete (UHPC) is a modern composite material with extremely good mechanical characteristics. Component materials and curing regimes significantly affect the properties of UHPC. For this reason, the influence of supplementary cementitious material (metakaolin) and curing regimes (accelarated curing) on the properties of UHPC has been analyzed. With advances in concrete technology, ultra-high performance concrete (UHPC) has become a new focus for researchers and the concrete industry. UHPC is characterized by high compressive strength and excellent durability properties resulting in lighter structures and longer life. Unlike conventional concrete, On the other side optimization of UHPC mix is also necessary to get the desired result. The optimized particle-packing allowed an increase in the concrete compressive strength leading to what was called Ultra-High-Strength Concrete (UHSC), and also an increase in the durability performance of concrete. Particle packing has
