In this study, the effect of cement content on concrete performance in corrosive environments is investigated on concrete mixtures having the same water/cement (w/c) ratio. Three w/c ratios (0.40, 0.45 and 0.50) were used and for each w/c ratio three mixtures were prepared with cement contents 350, 400 and 450 kg/m3. The compressive strength, electrical resistivity and chloride diffusivity of t...

Experimental results of the mix design and fresh properties a proposed concrete for 3D printing are presented in this paper. Layer-by-layer sample components were built by designed extruded through nozzle. The two most critical rheological extrudability buildability as they both highly influenced proportion presence superplasticizers. Therefore, study focused on approaches laboratory test metho...
