“…7,8 In the field of composite materials multiple materials such as fillers and reinforcements have been combined with these cements. [9][10][11][12] As Wollastonite powder and the phosphoric acid are mixing, the metal oxides dissolve in the acid, followed by an exothermic acid-base reaction, generating a dense paste that hardens in crystalline phases without the need of thermal processing, and thus forming calcium phosphate cement. [13][14][15] Three chemical equations have been proposed to explain the different reaction products of the mixture of phosphoric…”

The car tire waste have a tremendous adverse environmental impact in nature due to the large volumes generated worldwide, which requires multiple solutions that decrease as much as possible the tires disposed in landfills. Therefore, this research proposes to use part of the unused tire waste in a construction material, phosphate cement with ground rubber waste particles. For that, up to 12wt% of tire waste has been incorporated to cement. The samples characterization was conducted with scanning electron microscope; X-ray diffraction; compressive strength; thermal stability at 50 and 100°C; density; and Weibull statistics. Results show that this composite can be used as a building material therefore as an environmental solution for the rubber tire waste, mainly in applications requiring similar compressive strengths than concrete with ordinary Portland cement. Weibull statistics showed compression strength changing from 2.85 to 38.29 MPa, which is typical in construction materials and also it enables it to be used as building material. Density of samples was between 1.0 and 1.6 g/cm 3 , which open up applications for precast panels or other lightweight solutions.

“…The world today demands new technologies for the production of ceramics that enable the industry to optimize the energy consumption and to minimize wastes by using them in other applications or processes. This is the case of using alternative ceramic materials like phosphates and geopolymers to hold large amount of wastes [10,11], traditional building materials with similar goals [12], or developing new manufacturing processes that use these unutilized materials [13]. Particularly in the processing, there is a limitation in the feasibility of traditional technology-related methods to produce complex-shaped ceramic-based parts with the desired compositions, microstructures and properties.…”

Direct ink writing technique, an extrusion based additive manufacturing process, has been used to fabricate kaolinite clay based-ceramics with several inexpensive ceramic powders: lime, fly ash and talc. All the above materials are commonly used in the traditional ceramics industry, in both small and large industries, and therefore available worldwide. This research shows the simplicity of the process feasible not only for companies but also for individual users. The samples were fabricated with water to clay ratios (W/C) between 0.68 and 0.72. Additives were tested in 3.0, 5.0 and 7.0 wt.% with respect to the clay contents, although 3 wt.% of additives worked best. Cylindrical samples were fabricated with 20 mm in diameter and 20 mm in height in order to test their compressive strength and density. Measurement samples were previously cured for three days at room temperature and then exposed to 1100°C for 1 h. The powdered additives and their corresponding mixtures with clay were characterized with scanning electron microscopy, X-ray fluorescence and X-ray diffraction techniques. Results showed that samples with 0.70 W/C ratio and using fly ash as an additive were the best in terms of workability, mechanical properties and surface finishing.

“…Colorado et al had carried out intensive research on this type of CBPC composite. Higher performance structure CBPC composites were manufactured with the reinforcements, for instance, nano-fibers, graphite nanoplatelets (GNPs) [ 15 ], glass fiber and carbon fiber [ 16 ]. The results from Colorado’s studies showed that the different fibers improved the properties of CBPC composites at different ranges.…”

“…However, the interfaces between CBPC matrix and crystalline phases looks almost cracked, it should be conducted more research to improve the adhesion [ 15 ]. For the CBPC prepared by pultrusion method, the bending strength increased by a factor of 29 and 17 for pultruded carbon fiber and pultruded glass-fiber reinforcement CBPCs [ 16 ]. However, the pultrusion technique is complicated and higher cost.…”

In this study, chemically bonded phosphate ceramic (CBPC) fiber reinforced composites were made at indoor temperatures. The mechanical properties and microstructure of the CBPC composites were studied. The CBPC matrix of aluminum phosphate binder, metakaolin, and magnesia with different Si/P ratios was prepared. The results show that when the Si/P ratio was 1.2, and magnesia content in the CBPC was 15%, CBPC reached its maximum flexural strength. The fiber reinforced CBPC composites were prepared by mixing short polyvinyl alcohol (PVA) fibers or unidirectional continuous carbon fiber sheets. Flexural strength and dynamic mechanical properties of the composites were determined, and the microstructures of specimens were analyzed by scanning electron micrography, X-ray diffraction, and micro X-ray computed tomography. The flexural performance of continuous carbon fiber reinforced CBPC composites was better than that of PVA fiber composites. The elastic modulus, loss modulus, and loss factor of the fiber composites were measured through dynamic mechanical analysis. The results showed that fiber reinforced CBPC composites are an inorganic polymer viscoelastic material with excellent damping properties. The reaction of magnesia and phosphate in the matrix of CBPC formed a different mineral, newberyite, which was beneficial to the development of the CBPC.
