“…Sin embargo, esta acción puede reducir entre un 60-70 % el consumo de combustibles fósiles en el horno de producción de cemento [7], [14]. También se evidenció la utilización de residuos de comida como combustible, pero esta alternativa es un poco compleja de implementar debido a los altos contenidos de humedad en este recurso que deben ser removidos, por lo que se prefiere derivar este tipo de recursos a revalorización mediante su uso como materia prima en la producción de biogás o biodiesel [56]. Cualquiera sea el tratamiento de revalorización de este tipo de residuos biodegradables, diferentes a una disposición final en relleno sanitario, evita la emisión de gases efecto invernadero (CH4) por la descomposición de estos residuos al interior del relleno [56], [57].…”

El presente artículo contempla una revisión bibliográfica de las medidas que pueden llevarse a cabo dentro de la industria de producción de cemento, para hacer un consumo racional y eficiente de los recursos energéticos demandados, y, al mismo tiempo, mejorar los indicadores de sostenibilidad, gracias a la disminución en la emisión de contaminantes y GEI. La revisión inicia con la caracterización de esta industria a nivel mundial, consumos específicos, procesos, equipos y materias primas, para establecer en cuáles etapas del proceso existen oportunidades de mejora en el consumo energético. Posterior a esto, se describen las medidas en eficiencia energética de los equipos macroconsumidores de energía, como lo es el horno de producción de clinker. Por último, se muestran posibles sustitutos a los combustibles fósiles convencionalmente usados y tecnologías que aprovechan las energías renovables, con el fin de buscar una industria eficiente y sostenible.

“…The solar calciner has been designed to either fully replace or reduce the use of the current calciner, which is fuelled by petroleum coke, a fuel commonly utilised in cement production plants (Georgiopoulou andLyberatos 2018, Tsiligiannis andTsiliyannis 2019). For this reason, three solar scenarios are defined: one where the cement production is carried out solely in the solar calciner and two hybrid options where solar and conventional calcining are combined.…”

Cement production is a highly energy-intensive process, contributing 7% to global CO 2 emissions. Over 80% of the energy used in cement production is consumed by the calcination process. This paper considers a novel solar thermal technology for calcination, to investigate if it could help mitigate the climate change and other environmental impacts from cement production on a life cycle basis. The following three solar options are compared to conventional fossil-fuel calcination via life cycle assessment: a full solar system, which provides all the required thermal energy, and two hybrid systems, where the solar system provides 14% and 33% of the thermal energy, respectively. The results show that all three solar options have lower impacts than conventional calcination in 14 out of 17 categories. The full solar system is the best alternative, with major reductions in climate change (48%), fossil depletion (75%), photochemical ozone formation (92%) and terrestrial ecotoxicity (79%). Based on insolation levels in different parts of the world, the solar systems could be applied to 26% of current global cement production. This would reduce the climate change impact by 15-40%, as well as most other impacts by 14-87%, depending on the fuel mix. However, a limiting factor might be two times greater land occupation than by the conventional process. Furthermore, the solar system has higher human toxicity-cancer (102%) and metals and minerals depletion (6%) due to the construction of solar facilities. Coupling conventional calcination with carbon capture and storage (CCS) is more efficient in reducing the climate change impact (63%) than the solar system (48%) relative to conventional calcination without CCS. However, adding CCS to the solar calciner would still be a better option, decreasing the impact by 81% relative to conventional calcination without CCS. These findings will be of interest to the solar and cement industries as well as other industrial sectors using hightemperature processes.

The manufacturing process of OPC results in considerable Carbon dioxide (CO2) emission.…”

The present work reports an efficient way of capturing real-time crack propagation in concrete structures. The modified spectral analysis based algorithm and finite element modeling (FEM) were utilised for crack detection and quantitative analysis of crack propagation. Crack propagation was captured in cement-based composite (CBC) containing saw dust and M20 grade concrete under compressive loading using a simple and inexpensive 8-megapixel mobile phone camera. The randomly selected images showing crack initiation and propagation in CBCs demonstrated the crack capturing capability of developed algorithm. A measure of oriented energy was provided at crack edges to develop a similarity spatial relationship among the pairwise pixels. FE modelling was used for distress anticipation, by analysing stresses during the compressive test in constituents of CBCs. FE modeling jointly with the developed algorithm, can provide real-time inputs from the crack-prone areas and useful in early crack detection of concrete structures for preventive support and management.
