Study of Factors Affecting Productivity of Pumped Concrete for Multistory Buildings

A study is made to find factors affecting the efficiency and productivity of the pumped concrete and utilization of pumping equipment resources in the cast in situ concreting of buildings. The study involved elaborating general information about pumped concrete, factors affecting productivity of concreting in high rise building, equipments and machineries required for pumping and requirements of pumped concrete. Other factors affection the placing rates have also been studied. Other factors affection the placing rates have also been studied. A relation between height of building and speed of concrete placing is derived using the observation, during the project the methodology adopted was to visit site and collect data and further analyze it to draw conclusion. The study is similar to project carried out in Hong Kong, Japan , with some addition about factors that cause loss of productivity of concrete pumping and the information about the pumping equipments . In Hong Kong, project the speed of placing of pumped concrete was found out
