  • Different Grades of Concrete, Their Strength and Selection

    Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

  • Concrete Batching - an overview | ScienceDirect Topics

    Concrete batching is generally conducted at plants located at various strategic positions around a city or town to minimize transport time. Raw materials are mixed in elevated bins and placed directly into concrete trucks for final transport. This process is primarily powered by electricity, with small amounts of other fuels used on each site by small excavators used to move raw materials, etc.

    Therefore, 270 lb of water divided by a water-cement ratio of 0.42 requires a cement content of 643 lb. The bulk volume of coarse aggregate recommended when using sand with a fineness modulus of 2.80 is 0.62. Since it weighs 100 lb/ft3, the ovendry weight of coarse aggregate for a yd3 of concrete is 100 x 27 x 0.62 = 1674 lb/yd3 of concrete.
