Why Rebar Spacing is Crucial - NPCA - Precast concrete

Concrete that has an impressive compressive strength of 4,000 psi has maybe 400 psi of tensile strength Not so strong in tension! Since reinforcing steel can withstand much higher tension or stretching forces than concrete, we use steel to withstand the tensile stresses that build up in the product when it is loaded
