Pore fluid composition under marine exposure of steel fibre reinforced concrete
AbstractThe paper presents some results from a continuing study of the marine durability of steel fibre reinforced concrete. Two steel fibre 8 developed which were reinforced with three types of steel fibres. The cement content of the mixes was 430 kg/m3 and 590 kg/m3.Prism specimens of these mixes were cured under marine splash and tidal zone exposure, both in the laboratory and at Aberdeen beach, for up to 2000 wet-dry cycles (1250 days). The paper presents results of chemical analysis of the pore fluid extracted from different depths of these samples. The results show that Cl− concentrations are markedly higher in specimens cured under laboratory marine spray cycles compared with beach cured specimens. The pH of the pore fluid is depressed in the surface zones of specimens and increases gradually with depth to values in excess of 13.
