The Mixing and Transportation of Ready-mixed Concrete

Ready-mixed concrete is defined as concrete that is ,manufactured for delivery to a purchaser in a plastic or unhardened state. During the last 60 years, the ready-mixed concrete industry has experienced tremendous growth worldwide. For example, there are many companies operating 10,000 plants, small concrete mixer, and pumps that furnish over two-thirds of the total concrete consumed in the country. Six or seven percent of the companies produce 50 percent of the ready-mixed concrete and each operates more than 100 truck mixers.

Concrete is batched and mixed in accordance to some standard specifications for ready-mixed concrete. Most of the plants are equipped with automatic batching system and controls made possible by the use of microprocessors and computers. Truck mixing and transport rather that central mixing is still the commonly used method of mixing in some countries although, due to better quality control most ready-mixed concrete plants now use truck mounted concrete pump for the transportation and pumping of centrally mixed concrete. Stationary mixers of sizes up to 9m³ which can be of the tilting or the nontilting types, open-top revolving blade or paddle type with rear or with front discharge, are commonly used. In the past 25 years, for important jobs there has been a trend to move away from the prescriptive to the performance-based specifications; also, ready mix concrete produces are assuming greater responsibility for mixture proportioning and quality control.
