“…Lower limits of detection corresponding to three times the standard deviation (n D 6) for blank measurements were 198 ppm for Na 2 Major elements in the phosphate rock standard reference material (NIST SRM 694) were determined using the present method to confirm the certainty of analytical values of ten elements in sewage sludge ash (Table 2). Analytical results obtained using the present method agreed well with the certified value, except for MnO.…”

“…It has been used in producing cement mortars [2]; concrete mixtures [3]; bricks [4]; as fine aggregate in mortars [5]; asphalt paving mixes [6]; ceramic materials [7]. The control of the initial SSA composition and the application of a suitable heat treatment allow for the formation of various crystalline phases resulting in desirable properties.…”

“…Some plants have boilers and turbines that generate electric power from those gases, although the power output is fairly small unless the solids content in the sludge is significantly higher than 30% (7,8). Prior studies showed that SSA can be used in brick manufacture (9)(10)(11), as fines in mortars (12,13), to prepare synthetic aggregate (14)(15)(16)(17) and as aggregate in hot mix asphalt (18). SSA has likewise been used to produce phosphoric acid (19).…”

ABSTRACT:The present study explored the technological feasibility of re-using sewage sludge ash (SSA) as a Portland cement replacement in commercially manufactured pre cast concrete blocks. The blocks analysed were made to the guidelines laid down in Spain's National Plan for Waste Water Treatment Plant Sludge, 2001Sludge, -2006, and European Union specifications (CE marking) for such products. Performance was compared in three families of blocks, with 0, 10 and 20% SSA. The findings proved that SSA is apt for pre cast concrete block manufacture and that, in addition to the economic and environmental benefits afforded, its use would improve certain of the properties of conventional block. RESUMEN: Uso potencial de ceniza de lodo de depuradora (CLD) como sustitución de cemento en bloques dehormigón prefabricados.El objetivo de esta investigación es estudiar el uso potencial de las cenizas de lodos de depuradora (CLD), como sustitución del cemento Portland en bloques de hormigón prefabricados, de forma que se pueda lograr una revalorización de este material de desecho mediante este procedimiento. La metodología utilizada en este trabajo se rige por las directrices del Plan Nacional Español de Lodos de Aguas Residuales de 2001-2006, y por las exigencias del Consejo Europeo (marcado CE), que es obligatorio para este tipo de productos. Se han utilizado dos niveles de sustitución de cemento (10% y 20%), y todos los resultados han sido referidos a las muestras control. Los resultados obtenidos muestran que es posible utilizar una sustitución parcial del cemento por CLD, en la fabricación de bloques de hormigón prefabricados, y por lo tanto, se pueden conseguir beneficios económicos y ambientales, así como la mejora de una serie de propiedades.
