Description

  The present invention relates to an apparatus for producing ready-mixed concrete that can be manufactured on-site using ready-mixed concrete.

  Conventionally, ready-mixed concrete is a ready-mixed concrete maker who puts water, sand, gravel and cement into a mixer truck, transports it to the construction site while kneading, and places it in the construction site via a shooter or concrete pump truck.

Because of this, quality of the ready-mixed concrete will cause problems if it is not placed within one hour, so the transportation time between the ready-mixed concrete manufacturer and the construction site is limited to within one hour, and a large amount of ready-mixed concrete is cast. In the case of installation, there was a drawback that securing the mixer truck and transport management were difficult.
