Ready Mix Concrete - Definition “Ready mix concrete is concrete whose components are proportioned away from the construction site for delivery to the construction site by the truck in a ready-to-use-condition.”

Transit Mixer in late 1950’s History In 1909, the residents of Sneridan, Wyoming could have witnessed the birth of Ready Mix concrete industry. Prior to World War I, concrete was produced in stationery plant mixer hauled to construction sites in dumps trucks. Transit Mixer in late 1950’s

Need for Ready Mix concrete Requirement for higher grades of concrete Correct accountability ingredients Rapid development of infrastructure industry Increased demand of concrete Possibility of manufacture of desired grades Mega project demands higher output Timely supply of reliable concrete

Progressive growth of Ready mix concrete in India PHASE TIME PERIOD IN YEARS CEMENT CONSUMPTION IN % VOLUME OF R.M.C PER YEAR PHASE I 1992-2010 5-10% of cement consumption 20 million cubic meter/RMC/year PHASE II 2020-2050 20-25% of cement consumption 70 million cubic meter/RMC/year PHASE III 2050 Onwards 25-40% of cement consumption 100 - 150 million cubic meter/RMC/year

Advantages Of Ready Mix Concrete Quality assurance Elimination of manual errors Mass production of concrete possible Water cement ratio maintained Reduced material wastage Labour cost saved Design mix as per IS standards resulting in standard deviation and improved characteristics.

Disadvantages Of Ready Mix Concrete The materials are batched at a central plant, and the mixing begins at that plant Generation of additional road traffic; furthermore, access roads, and site access have to be able to carry the weight of the truck and load. Concrete's limited time span between mixing and going-off
