Reuse of waste fresh concretes can contribute the resource saving and control of industrial wastes emission. This study deals with an application of the waste fresh concrete as a preceding mortar of the subsequent concrete pumping construction. Addition of super set-retarding agents and superplasticizers to the waste fresh concrete and subsequent wet-screening results in the Eco-Mortar whose basic properties are presented. Recovery factor of the Eco-Mortar as a function of screening mesh size and effect of the chemical admixtures on the quality of the Eco-Mortar are discussed in this paper.
