Abstract
New composites of construction materials were developed and characterized based on ink sludge (IS) waste (50-60Â wt.%) in combination with wood ash (15-30%) and lime production waste (15-25%). IS contains NiO (2.4%) and ZnO (1.1%). The materials uniaxial compression strength reached on the 3rd day 3.9Â MPa, on the 7th day 4.8Â MPa, and on the 180th day 11.7Â MPa. Studies by the XRF, XRD, DTA, TG, SEM, EDS and LAMMA methods explain the strengthening of materials by synthesis of mainly amorphous carbonates. Comparison of leaching and solubility of raw materials with final products show that IS can be successfully used for improvement of the mechanical properties of the developed composites as an environmentally friendly construction material. New materials can be economically attractive because of only cheap industrial wastes utilization as raw materials. At the end of service as construction material, it can be used as an inert demolition waste.
