In vitro evaluation of additives allowed for high strength concrete (HSC) and foam concrete

Thanks to significant advances in materials science, researchers have managed to fabricate and develop different types of concrete proportional to application of new concrete technologies, such as high strength concrete (HSC) and foam concrete. The current paper presents the results of in experimental studies on foam concrete and its application. In addition, the effect of various parameters such as cement content, Water/Cement ratio as well as application of additives has been studied in mix design. In HSC, interaction between concrete constituent materials plays an important role in mechanical properties and compressive strength of concrete. Therefore, an appropriate understanding of these factors helps us select the suitable type and amount of materials in order to make a concrete with desirable behavior and strength. The methods and theoretical procedures used in the study is based on the ACI codes. This study aims to investigate the effect of using Micro Silica and plasticizer on strength of HSC. Based on the obtained results, the optimum percentage used for concrete mix design and positive effects of these materials on concrete property were confirmed.
