Inference System

Sustainability assessment of concrete manufacturing processes has recently received great attention among scholars and practitioners. While most of the studies on sustainability assessment of concrete manufacturing processes focus on economic and environmental issues, those which consider all three dimensions of sustainability (social, economic, and environmental) simultaneously are rather limited. In this study, a hybrid approach of fuzzy inference system and analytical hierarchy process (AHP) is proposed in order to evaluate the sustainability level of concrete manufacturing processes based on Life Cycle Assessment (LCA) principals. AHP is applied to weight the selected sustainability elements and sub elements. Afterward, fuzzy inference system is used to evaluate the sustainability level of concrete manufacturing processes. The practicality and applicability of the proposed approach are examined by conducting sustainability assessments of four different concrete manufacturing processes: (1) 100% of Portland cement (2) 35 % slag cement and 65% Portland cement (3) 50% slag cement and 50% Portland cement (4) 20% fly ash and 80% Portland cement. The results disclose the more sustainable concrete manufacturing process which is 50 % of Slag cement and 50% Portland cement.

Presented article is of interest to specialists in the field of building materials. The provided information describes nanostructured binders (NB) that are promising in the production of building materials for various purposes. As a result of conducted researches the character of hardening kinetics of NB with different composition was identified, which is similar to the classic representative of binding system – Portland cement. The importance of keeping the technological and temporal parameters of NB receipt by comparing it with a quartz suspension was substantiated. Also a system for monitoring the grinding process allowing to control and manage the technology was provided.

The OPC is silicate cement normally utilized for concrete masonry units and for all uses where the concrete isn't dependent upon unique sulfate hazard or where the heat produced by the hydration of cement isn't objectionable. It has incredible resistance from breaking but has a smaller amount of resistance from chemical attacks. Keywords: OPC, Limestone, clinker etc.

Mineralogical Phases

Portland cement is the result of the calcination of a properly raw mix of limestone and clay, at high temperatures, and its manufacturing process is responsible for high environmental impacts, such as the exploitation of the deposits of these raw materials. In this context, the search for alternative raw materials becomes necessary. Thus, the present work analyzed the feasibility of the use of granite rock fines (GRF), waste generated in the process of production of aggregates for civil construction (gravel), aiming at the manufacture of Portland clinker. Firstly, the raw materials were characterized physically, chemically and mineralogically and, from these results, different raw mixes were prepared with different weight substitution of clay by the GRF (0%, 25%, 50%, 75% and 100%). Clinkers were produced from the calcination of the raw materials, and these were characterized mineralogically, in order to verify the optimal incorporation content of the GRF. Thus, it was possible to observe that the substitution of clay by GRF is technically viable and does not significantly interfere in the formation of mineralogical phases of Portland clinker.

Source Materials

The microelectronics industry is heavily tasked with minimizing contaminates at all steps of the manufacturing process. Particles are generated by physical and/or chemical fragmentation from a mothersource. The tools and macrovolumes of chemicals used for processing, the environment surrounding the process, and the circuits themselves are all potential particle sources. A first step in eliminating these contaminants is to identify their source. Elemental analysis of the particles often proves useful toward this goal, and energy dispersive spectroscopy (EDS) is a commonly used technique. However, the large variety of source materials and process induced changes in the particles often make it difficult to discern if the particles are from a common source.Ordination is commonly used in ecology to understand community relationships. This technique usespair-wise measures of similarity. Separation of the data set is based on discrimination functions. Theend product is a spatial representation of the data with the distance between points equaling the degree of dissimilarity.
