Introduction Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure. The compressive strength of concrete is the most common performances measure used by engineer in designing buildings and other structures. The compressive strength is measured by breaking concrete specimen in a compression-testing machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

introduction of concrete as a construction medium and the true arch as a structural component made it possible for the Romans to build strong‚ elaborate‚ expansive structures that would endure the test of time. Concrete Roman concrete‚ called opus caementicium‚ was made by mixing traditional lime mortar with stone aggregate called caementa. This material used less water and was very thick compared to modern concrete; therefore it was laid rather than poured (Roman Architecture‚ n.d.). Concrete was an important
