Abstract

THE CONCRETE CONSTRUCTIONS USED IN HOSTILE AND CORRODING ENVIRONMENTS SUCH AS MARITIME STRUCTURES, INDUSTRIAL AND CHEMICAL ENVIRONMENTS ARE FACED WITH VARIOUS ISSUES, WHOSE MAIN CAUSE IS LOW STRENGTH OF CONCRETE FOR SPECIAL APPLICATIONS AND ITS HIGH PERMEABILITY AGAINST WATER AND CONTAMINANTS. TODAY, IT IS COMMON TO VASTLY USE POLYMER MATERIALS IN ORDER TO IMPROVE THE CONCRETE FEATURES. BY REPLACING THE WHOLE CEMENT MATRIX BY THE POLYMER CARRYING CONCRETE, A MIXTURE CALLED POLYMERIC CONCRETE IS OBTAINED. THESE MIXTURES CAN BE USED IN LARGE HYDRAULIC CONSTRUCTIONS IN ORDER TO LOWER THE CORROSION, IN BRIDGES ARMED CONCRETE CONSERVATION AGAINST THE PENETRATION OF SALT AND THE CORROSION OF THE STEEL WITHIN THE CONCRETE, IN THE FLOORS OF INDUSTRIAL AND CHEMICAL ENVIRONMENTS, THE TUNNELS, DAMS AND MARITIME STRUCTURES COATING AND ALSO IN FAST RESTORATION OF DAMAGED CONCRETE CONSTRUCTIONS. IN THIS RESEARCH, AFTER SELECTING THE MATERIALS AND DETERMINING AN ADEQUATE COMPOSITION AND A PROCESSING METHOD CONSIDERING THE COMMON EQUIPMENT, THE POLYMERIC CONCRETE WITH SUPERIOR PHYSICAL AND MECHANICAL FEATURES COMPARED TO THE NORMAL CONCRETE WAS PRODUCED WITH THE FOLLOWING SIGNIFICANT FEATURES: PRESSURE STRENGTH OF 107 MPA (3 TO 5 TIMES MORE THAN THE NORMAL CONCRETE), BRAZILIAN STRENGTH OF 12.4 MPA, MORE THAN 15.6 MPA FLEXURAL STRENGTH, WATER PENETRATION PERCENTAGE OF 0.18%, DENSITY OF 2.14 GR/CM3, MORE THAN 2.3 MPA COHESION, AND NO WEIGHT REDUCTION AFTER PASSING TWENTY 24-HOUR CYCLES IN THE SATURATED SODIUM SULFATE MIXTURE.
