Effect of organic materials on the solidification of heavy metal sludge.(environmental remediation materials research)
March 1, 2003... Abstract Solidification studies were conducted using three binders, viz., Portland cement (CEM), cement-fly ash (CFA) and lime-fly ash (LFA) to solidify a synthetic heavy metal sludge containing nitrates of Cr, Ni, Cd and Hg. The sludge to...

Protective patinas applied on stony facades of historical buildings in the past.
March 1, 2003... Abstract The ochre patina that covers the limestone facades of Palacio de Nuevo Baztan is composed of calcite, clay minerals, gypsum, quartz, potassium feldspar, alongside traces of calcium oxalates, calcium phosphates, iron oxides and...

Hydration of high-calcium quicklime with methanol--water mixtures.
March 1, 2003... Abstract In this study, hydration of quicklime was accomplished with different methanol-water mixtures. The greater the percentage of methanol, the more intense was the suppression of the hydration conditions. The reactivity was not...

Effect of coarse aggregate quality on the mechanical properties of high strength concrete.
March 1, 2003... Abstract This paper reports results of a study conducted to evaluate the effect of four types of coarse aggregates, namely calcareous, dolomitic, quartzitic limestone, and steel slag, on the compressive and tensile strength, and elastic...

Comparison of properties of steel slag and crushed limestone aggregate concretes.
March 1, 2003... Abstract Steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. This by-product that mainly consists of calcium carbonate is broken down to smaller sizes to be used as aggregates in asphalt...

Salt influence on evaporation from porous building rocks.
March 1, 2003... Abstract The evaporation process of saline solutions within porous building rocks has been studied. Twelve different porous rocks saturated in pure water and a NaCl solution, were dried in a moisture balance. The influence of pore...

The effect of alkali reactivity on the mechanical properties of concrete.
March 1, 2003... Abstract The effects of highly reactive aggregate, fused silica, and slowly reactive aggregate, Thames Valley sand, on the mechanical properties of concrete were investigated in this paper. The mechanical properties studied over a period...
