Abstract
A concrete mix, including: cementitious content between 25 and 200 kg/m3; fly ash content between 25 and 175 kg/m3; dirty sand with fine aggregates between 3% and 20%; water content between 150 I/m3 and 250 l/m3; and a chemical admixture comprising one or more components selected from the following: an acrylic, formaldehyde-free polymer-based admixture, modified in aqueous solution; a surfactant admixture configured to entrain micro air bubbles in concrete; and an organic polymer comprising hydrophilic groups for increasing the viscosity of the mixture.
