Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of ...

concrete reinforcement bars marked with a W can be considered as dual grade. Changes to ASTM A615-20 specification reduced the tensile strength requirements for A615 Grades 60 and 80 to 80,000 psi ...

In a recent development in construction materials research, a study published in Engineering by Peizhao Zhou and Peng Feng from Tsinghua University has introduced a new composite material. Named ...
