Abstract

THE CONCRETE CONSTRUCTION DEVASTATIONS, ESPECIALLY IN COASTS AND PORTS OF THE SOUTH OF IRAN, HAVE CAUSED AN IRREPARABLE SCATHE. THE RENOVATION OF SUCH CONSTRUCTIONS IS TOO EXPENSIVE, AND IF NOT FIXED BY APPROPRIATE MATERIALS AND PROPER TECHNIQUES, THE PROBLEM WILL REAPPEAR AFTER A SHORT PERIOD OF TIME. IN THE RECENT RESEARCH AND EXPERIMENTS, THE RENOVATION MATERIALS HAVE BEEN INVESTIGATED BY USING SUPERPLASTICIZER ADDITIVES AND NATURAL AND ARTIFICIAL POZZOLANS. THE MECHANICAL PROPERTIES OF THESE MIXTURES HAVE BEEN MEASURED, AND THE EXTENT OF THEIR CONTRACTION WAS DETERMINED. THE OLD AND NEW CONCRETE COHESION WERE MODIFIED USING THE COMMON TECHNIQUES, AND THEY WERE COMPARED WITHOUT USING THE MENTIONED MATERIALS IN THE NEW CONCRETE. THE RESULTS OF THE MENTIONED INVESTIGATIONS INDICATE THAT THE ORDINARY CONCRETE CANNOT PROVIDE THE FAVORABLE PROPERTIES OF THE RENOVATION CONCRETE SUCH AS STRENGTH, CONTRACTION AND COHESION.USING THE SUPERPLASTICIZER AND POZZOLANIC MATERIALS IMPROVES OLD AND NEW CONCRETE IN STRENGTH, CONTRACTION AND COHESION AS WELL, AND THE RESISTANCE OF THE MENTIONED RENOVATION CONCRETES IN HIGH EROSIVE ENVIRONMENTS, NEAR-COASTAL AND MARINE CONSTRUCTIONS IS MUCH HIGHER THAN THE ORDINARY CONCRETE.
