On site Concrete that is cast in place, on site, is called in situ concrete. Advantages to in situ concrete: 1) Adapts to any building shape. 2) It can be assumed to be more or less monolithic, since joints only occur as a result of different pourings to the same structure. 3) It is easily used for two way structural systems. 4) It is adaptable to post tensioning. 5) No cranes are needed. Disadvantages of in situ concrete: 1) Erection of formwork is time consuming 2) Concrete must cure before it is loaded 3) Quality control of finish surfaces is not assured
