Abstract

The main purpose of this research is to develop technically, economically, and environmentally attractive construction materials from sediments dredged from Brazilian seaports. The final composite material contains 50 to 60 wt% in mass of sediments and thus creates an opportunity to diminish the pollution of the Atlantic Ocean. Construction and demolition debris (20–35%) and lime production wastes (15–30%) were used as components of the composite materials. Uniaxial compressive strength values reach 6.3 MPa on the 3rd day and 14.5 MPa on the 90th day; linear shrinkage varied between 0.07% and 0.35%, water absorption - between 11.0 and 13.4%. These values attend the demands of Brazilian norms on conventional bricks, blocks, etc. XRD, XRF, SEM, EDS, AAS and LAMMA analysis showed that amorphous new formations are responsible for material strengthening.
