Reversing drum type the cylindrical drum consists of two set blades one set of blade attached to the drum mixes the mix while another set of blades rotates in opposite direction which forces to discharge the concrete

Concrete -- a mixture of aggregates (fine or coarse), cement and water -- is an essential building material widely used in modern-day construction because of its strength, durability and versatility. Depending on the ratio of its constituent ingredients, concrete can be produced in a wide range of compressive strength or grades. Typically grades of concrete vary in the range of M5 to M70. M5 grade concrete has a compressive strength of 5 MPa whereas M70 grade concrete has a compressive strength of 70 Mpa. Concrete of grade M5 to M20 are generally used for applications which don’t require high strength, concrete of grade in between M25 and M45 are used for reinforced concrete applications or construction requiring standard strength and high strength applications use concrete with grade M50 to M70. These days, concrete is used in the construction of houses, bridges, high rises, canals, roads, tunnels and several other structures.
