RESUMENEn este artículo se presentan resultados obtenidos en distintas propiedades relacionadas con la durabilidad y características resistentes de morteros de cemento parcialmente sustituidos con diferentes residuos agrícola e industriales que presentan actividad puzolánica: ceniza de lodo de depuradora (CLD), ceniza volante (CV), residuo de catalizador de craqueo catalítico (FCC), ceniza de cascara de arroz (CCA), reforzados con acero. Los resultados presentados demuestran que es posible un desarrollo sostenible de la industria de la construcción. Esto puede conseguirse mediante la reducción del contenido de clinker en los cementos y reutilizando subproductos industriales y agrícolas con un adecuado nivel de durabilidad de los materiales de construcción elaborados a partir de ellos.Palabras claves: durabilidad; sostenibilidad; subproductos industriales; subproductos agrícolasABSTRACTThis paper presents the results obtained in the evaluation of a series of properties related to durability and strength of steel reinforced cement mortars partially substituted with different agricultural and industrial residues presenting pozzolanic activity: sewage sludge ash (SSA), fly ash (FA), spent catalytic cracking catalyst (FCC) and rice husk ash (RHA). These results show that it is possible to achieve a sustainable development in the construction industry. This can be obtained by reducing the clinker content in cement and reusing industrial and agricultural byproducts with an appropriate level of durability of the construction materials fabricated from them.Key words: durability; sustainability; industrial byproduct; agricultural byproduct

In the late few years, Egypt has been suffering from a dark clouds resulting from burning rice husk. Studies have been undergoing to study the possibility of using rice husk instead of burning it and soiling environment. The construction industry plays an important role in many countries. Waste materials are new challenge choice for use as construction materials, because construction materials coming from a natural source are irreversible. Rice Husk Ash (RHA) is one of waste materials from agricultural industry. It has some special characteristics that can enhance the properties of concrete, when it is used as a part of the ingredients in concrete mixes. The objective of this paper is to study the mechanical properties of concrete containing ordinary Portland cement, rice husk ash and super plasticizer compared to the silica fume concrete. The water cement ratio was equal to 35% by weight for all tested specimens whereas the slump was constant at 100 +/- 20 mm.

Sewage sludge is a by-product generated within the wastewater treatment process. Severe concern arised as the sludge are massively been dumped to the landfill and it may affect the environment. Many studies had been conducted in reusing the sewage sludge as construction material, where it is one of the optional ways to solve the issue. In this study, dried sewage sludge was incinerated with two different temperatures in order to produce sewage sludge ash (SSA), which are 800°C and 1000°C. After few processes, this SSA then reused in mortar as cement replacement with the replacement percentage of 5%, 10%, 15% and 20% by weight. The strength performance of mortar specimens was investigated after 7, 28, 60 and 90 days of curing. From the results, it is clearly showed that the compressive strength of all mortar specimens increased when the period of curing was prolonged. Moreover, almost all compressive strength of SSA mortars was higher than the control mortar. Therefore, there is potential to reuse this waste material as part of construction materials and hence, its plays an important role for future researches in minimisation of waste.

AbstractInnovation in construction is presented as a necessary aspect in the answer that the construction industry must provide to solve its negative impact on the environment. Original and innovative research is only part of the work to be accomplished. More important is the implementation of innovation in practice, where traditions are strongly rooted in society, and safety and long term reliability are required. Lessons from nature and study of durable examples handed down from the pasts serve as guidelines to innovative approaches that contribute to sustainability.

Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty in phosphate rock supply, phosphorus recovery from sewage sludge ashes has become interesting. In the present work, ashes from incineration and gasification of the same sewage sludge were compared in terms of phosphorus extractability using electrodialytic (ED) methods. The results show that comparable recovery rates of phosphorus were achieved with a single ED step for incineration ashes and a sequential combination of two ED steps for gasification ashes, which was due to a higher influence of iron and/or aluminium in phosphorus solubility for the latter. A product with lower level of metallic impurities and comparable to wet process phosphoric acid was eventually obtained from gasification ashes. Thus, gasification becomes an interesting alternative to incineration also in terms of phosphorus separation.

One of the major current environmental concerns is the excessive or inefficient consumption of non-renewable natural resources. The construction industry is one of the largest consumers of natural raw materials, playing an important role in the degradation of the environment. Recycling and reusing are concepts that can be effectively applied in the formulation of construction materials, especially mortars. In particular, calcareous quarry can replace, at least to some extent, the cement used in the composition of bricklaying mortars. The objective of this study was to prepare and characterize mortars containing calcareous quarry. The mortars were prepared using Portland CP II F – 32 cement, CH I hydrated lime, river sand and tap water. Different concentrations of residues, ranging from 5 to 30% were used to replace the cement. Mortars with volume ratio of 1:0.5:4.5, commonly used in bricklaying structural masonry, were evaluated. The water to cement ration was set to 1.45. The residue used was fully characterized to determine their specific mass, unitary mass, particle size distribution and morphology, and composition. The mortars were characterized both in their fresh and the results compared to those obtained from a residue-free composition. The results showed that the use of calcareous quarry partially replacing the cement did not significantly affect the performance of the mortars. Compositions containing up to 30% of calcareous quarry can be classified according to NBR 13281 (ABNT, 2005) as bricklaying mortars, and can be used by the construction industry.
