The applications of Artificial Intelligence (AI) are widely considered for specifying the mechanical properties of concretes and noticeable results are reported. Hence, this systematic review aims to study different methods presented in various research in this regard. The gaps and shortcomings of the previous studies are presented, which can shed light on future studies by presenting new ideas. The major issues that the research seek to examine are accuracy and authenticity. The experimental costs and time spent specifying the concrete&#39;s mechanical properties will significantly reduce using AI techniques. It is recommended to employ AI methods more widely for composite materials. The suggestions presented here can be beneficial to those aiming to advance in this significant and offer more innovations.</span></span></span></span><br> &nbsp; artificial intelligence, civil engineering, mechanical properties, concrete, composite materials 93 110 http://ijoce.iust.ac.ir/browse.php?a_code=A-10-66-364&slc_lang=en&sid=1 M.
