Concrete is a composite construction material composed primarily of aggregate‚ cement‚ and water. There are many formulations‚ which provide varied properties. The aggregate is generally a coarse gravel or crushed rocks such as limestone‚ or granite‚ along with a fine aggregate such as sand. The cement‚ commonly Portland cement‚ and other cementitious materials such as fly ash and slag cement‚ serve as a binder for the aggregate. Various chemical admixtures are also added to achieve varied properties

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.

Prestressed concrete construction Prestressed concrete Prestressed concrete is a method for overcoming concrete’s natural weakness in tension. It can be used to produce beams‚ floors or bridges with a longer span than is practical with ordinary reinforced concrete. Prestressing tendons (generally of high tensile steel cable or rods) are used to provide a clamping load which produces a compressive stress that balances the tensile stress that the concrete compression member would otherwise
