Zusammenfassung: | •New material from cellulose and paper production process, concrete waste and lime production wastes.•Axial resistance reached 4.81 MPa in 3-day age samples, 8.75 MPa in 180 days, and 9.61 MPa in 365 days.•By methods of XRD, SEM and EDS were founded the processes of the materials hardening.•Utilization of industrial wastes has high environment and economic efficiency.
The mechanical and physical properties of the composites developed from dregs, grits, and lime mud of the Kraft cellulose and paper production process (55–75%), concrete waste (10–25%) and lime production waste (0–25%), far exceeded the demands of Brazilian standards for bricks, blocks, and road-base construction materials. The study of the developed composites structure by XRF, XRD, SEM, EDS, and LAMMA methods demonstrated that new mainly amorphous formations were responsible for all attained properties. The industrial application of these construction materials would introduce excellent efficiency from an economic and environmental points of view. |
