Abstract

The present paper is a contribution to offer a new relationship between yield stress and plastic viscosity  of environmental cement pastes. The ash obtained from calcinations of sludge from wastewater treatment plants (WWTPs) under a temperature less than 550°C. Three samples of eco-cement have been developed by substitution of different amount of ash (5%, 10% and 15%) obtained into the clinker. The characterization of the workability of different cement paste is carried out using mini slump cone.
