Now a day’s pressure is escalating on the construction industry to adopt more environmentally sustainable methods to reduce CO2 emissions. Portland cement often constitutes to quite two-thirds of the embodied energy of concrete, and its production generates 5% of worldwide greenhouse emission. One efficient strategy to scale back the cement content without sacrificing performance is that the use of particle packing models (PPM) to mix- proportion concrete mixtures with low cement content. This study aims to analyze and quantify the behavior of concrete mixtures designed with the use of the continuous PPM to increase binder efficiency in concrete. Three q factors were selected in this study and properties in the fresh (i.e. slump test) and hardened state (i.e., compressive strength) are measured and analyzed.
