specification‚ status and its barriers. CONCRETE REINFORCEMENT - FRP REBAR Introduction Reinforced concrete is a common building material for the construction of facilities and structures. While concrete has a high compressive strength‚ it has a very limited tensile strength. To overcome these tensile limitations‚ reinforcing bars are used in the tension side of concrete structures. Steel rebars have been and are an effective and cost-efficient concrete reinforcement‚ but are susceptible

Concrete operations are the third stage of Piagetian cognitive development‚ during which children develop logical but not abstract thinking (Papalia p.351). The concrete operational stage begins around age seven and continues until approximately age eleven. During this time‚ children gain a better understanding of mental operations. Children begin thinking logically about concrete events‚ but have difficulty understanding abstract or hypothetical concepts. Piaget determined that children in the
