“…Its Ca/P, Al/P and Zn/P molar ratios, determined by SEM-EDS after 30 min of hydration, were 0.13 ± 0.06, 0.28 ± 0.05 and 0.22 ± 0.04 respectively. Such kind of phase has already been reported for zinc phosphate dental cement (Jabri, 2012), but has never been fully characterized. Its stoichiometry, assessed from mass balance calculations and Rietveld analysis, was (ZnO)0.20±0.03(Al2O3)0.12±0.04(P2O5)1.0±0.1.xH2O.…”

Wollastonite-based brushite cements are mainly used for refractory material applications, but they may also offer new prospects for the solidification/stabilization of hazardous wastes. Most studies on these binders have been focused on the characterization of the final products, on the associated microstructure or on the functional properties of the resulting materials. This work provides new insight into their setting and hardening process, by characterizing the evolution of both the liquid and solid phases with ongoing hydration.

“…For determining the optimal factor levels on concrete quality, experimental design methodologies such as Response Surface Methodology (RSM), Taguchi Methods and factorial design applications are widely used in literature [4][5][6][7][8][9][10][11][12][13][14]. Multi-Attribute Decision Making (MADM) methods are also combined with Taguchi methods where multiple responses are involved [15][16][17][18].…”

In this study, a fuzzy multi-response standard ready-mixed concrete (SRMC) optimization problem is addressed. This problem includes two conflicting quality optimization objectives. One of these objectives is to minimize the production cost. The other objective is to assign the optimal parameter set of SRMC's ingredient to each activity. To solve this problem, a hybrid fuzzy multi-response optimization and artificial neural network (ANN) algorithm is developed. The ANN algorithm is integrated into the multi-response SRMC optimization framework to predict and improve the quality of SRMC. The results show that fuzzy multi-response optimization model is more effective than crisp multi-response optimization model according to final production cost. However, the ANN model also gave more accurate results than the fuzzy model considering the regression analysis results.: Standard ready-mixed concrete; Multi-response optimization; Taguchi method; Fuzzy TOPSIS; Artificial neural networks.

“…Thus, the cement reveals a cored structure consisting primarily of non-reacted zinc oxide particle core embedded in a cohesive amorphous matrix of zinc aluminophosphate (glasslike phosphate). Aluminum phos-phate, in addition to its role as a retarder, contributes to the increase in mechanical hardness of cement [40], [45].…”

Apatites and Their Synthetic Analogues - Synthesis, Structure, Properties and Applications

The last chapter of this book provides brief description of utilization of apatites and phosphorus-bearing compounds in industry and material science research. Since the chemistry of phosphorus is quite complicated and a quickly developing field of science, the topics described below are only limited insights to chemically bonded ceramics and refractories, dental phosphate cements, oil-well cements, phosphate glasses and glass ceramics. Chapter continues with description of functional phosphate materials applied as solid oxide fuel cells electrolytes, sensors, phosphors, catalysts and coatings. The chapter ends with introduction of basic ideas for biological apatite in bone tissue engineering, collagen apatite composites, apatite layers and biocoatings.
