TL;DR: In this article, a resistivity technique has been developed and used to monitor the changes in permeability of five mortars and one concrete on exposure to sea-water, and all mixes studied showed a fall in their permeability on immersion in sea water.
Abstract: Synopsis Permeability is a fundamental property governing the durability of concrete in the marine environment and it has only recently been appreciated that some concretes exhibit a very significant reduction in permeability on immersion in sea-water. To investigate this phenomenon further, a resistivity technique has been developed and used to monitor the changes in permeability of five mortars and one concrete on exposure to sea-water. All mixes studied showed a fall in permeability (increase in resistance) on immersion in sea- water. Indeed 25 mm thick specimens of the two most permeable mortars showed a fall equivalent to over 20 mm of additional thickness after only 10 weeks. This increase is due to the formation of an aragonite-brucite layer on the surface of the mortar plus a more widespread progressive constriction of the cement paste pore system. This effect also has a considerable influence upon the absorption capacity of concrete after a period of drying, which is important in the tidal and sp...

TL;DR: In this paper, the effect of the addition of MWCNTs at the ratios of 0.15 to 1.15% of Portland cement on the compressive, tensile, and flexural strength; and resistance to the elevated temperature of the Portland cement mortar was evaluated.

TL;DR: In this paper, the authors evaluated the influence of hydraulic lime content on the properties of blended lime-hydraulic lime mortars with different percentages of natural hydraulic lime and found that these mortars are more promising to be used as repair mortars than the hydraulic lime one.

TL;DR: In this paper, the influence of sewage sludge, treated at temperatures between 300 and 800°C, on cement-based materials has been studied, and the clinker of CPJ 45 cement was partially replaced by sewage-sludge ash (SSA) admixture in mortar at various percentages.
