Concrete is a composite material obtained by mixing cement, sand, aggregates with water in suitable proportions. Concrete after mixing has to be transported at the final positions before setting takes place. Placing of concrete at its final position by keeping properties of plastic concrete intact is most important, as the quality of concrete depends of placing, at most care is needed. There are number of equipment's used for transportation and placing of concrete. In case of high rise structures and mass concreting works continuous flow of concrete at the desired height is essential, in such situations pumping concrete by concrete pumps is a common solution. Concrete pumps are the versatile equipment's having number of advantages. Since the concrete is placed under pressure no segregation, bleeding takes place, honeycombing is avoided so superior fishing quality of the concrete product is possible. With proper utilization of resources, speed and economy in concreting can be achieved. The timely completion of the project and reduction in site overheads helps in improved cash flow.
