The aim of this laboratory work is to produce high performance green concrete that can be used in hot weather. The compressive strength test was used to assess the mechanical properties and the performance with the supplementary cementitious materials. The concrete durability was evaluated by water absorption test, water permeability test and resist chloride penetration test. OPC was partially replaced by 30% of fly ash, 7% micro silica and 25% binary mixture of Fly ash and micro silica. The test results showed a good performance for the concrete and enhancement in the durability with the use of supplementary cementitious materials. Key words: Durability, HPC, Fly ash, Micro Silica, Green Concrete, Supplementary cementitious materials.

INTRODUCTION Ordinary Portland cement is considered as the main traditional binder that have been used for a long time to combine the fine sand and coarse aggregate in the presence of water to produce conventional concrete [1]. However of this crucial role in construction, the manufacturing process of Portland cement is an ecological harmful process due to the burning of the calcareous materials (limestone or chalk), (clay or shale) or a mixture of calcareous and argillaceous materials. The burning temperature inside the rotary kiln consumes high range level of energy. The burning temperature can reach to about 1450 °C to turn the raw materials to Clinker. Moreover, the heating process at each production batch should continue to keep the kiln ready to start the burning process [2]. For this reason, the cement manufacturing process is considered as the main factor that participate in CO2 emission. The World Cement
