PRODUCING STRUCTURAL LIGHT WEIGHT CONCRETE AND HIGH STRENGTH CONCRETE WITH MINIMUM

Many researches have been conducted on structural high strength lightweight concrete and its material, as well as the effects of these materials on the mechanical properties of structural lightweight concrete. The present study dealt with the production of high strength lightweight concrete which satisfies the ACI codes requirements through a trial and error procedure. 480 standard cylindrical samples were prepared and tested. 12 aggregate proportions were proved to be acceptable in terms of ACI codes that justify the construction of concrete structure by such high strength lightweight materials. Finally, economic evaluation was performed to investigate the feasibility of working with these materials in real world.
