Abstract:  
           
          In the current study, how planning and truck-mixer based 
          waste amounts per 1 m3 fresh ready-mixed concrete (RMC) can 
          be determined was presented. Toward this aim, the formation 
          process of the fresh RMC waste in construction projects was 
          first introduced in a detailed manner, together with an in-depth 
          literature review in this specific domain of the construction 
          engineering and management. Then, the measurement procedure 
          of the waste amount or coefficient of the fresh RMC was 
          revealed and discussed as a practical and creative planning 
          knowledge. Hence, a useful and realistic waste management 
          perspective about the cost and potential environmental savings 
          of the RMC waste was drawn.
