water absorption and smooth texture of finely ground quartz particles. Fig. 9, 10 described water reduction effect of adding crushed quartz filler to maintain a fixed flow of MgO-SF-QF ternary systems (Series 3, 4, 5). The replacement of cementitous materials by crushed quartz filler improves rheology considerably, expressed by the consistent reduction of water content while maintaining a minimum flow of 120-125 mm for workability. The amount of reduced water is proportional to the increase…

CHAPTER 1 EXECUTIVE SUMMARY TARPS recycles tarpaulin waste into bags. The bags are made out of tarpaulin, making it thicker than an average plastic bag and cannot tear apart easily like a paper bag would. Tarpaulin in nature are water resistant therefore the bags will not be affected by wet products and it will not melt when exposed in the rain unlike paper bags. If food was spilt in the bag it would be easier to clean it off or if the shoes put into it are muddy, cleaning the bag would not be…

chemistry, Mathematics, Thermodynamics, Heat Transfer, Material science etc., Tribological problem leads to the reason of metal failures than the mechanical problem such as fracture, fatigue and plastic deformation. 1.6.1 Friction Friction is the opposes that the motion (either sliding or rolling) of the object. This oppose force acts against to its motion is called friction force as shown in fig.1.7. The friction is not a property of material, but it is a system response. The ratio of…

MANUFACTURING COSTS: Functional Elements: The baby stroller is mainly composed of three materials: Nylon (woven, as fabric) Plastic (injection molded, for plastic parts) Steel (tubing, for frame) Fasteners are included in the assembly of different components of the strollers. The stroller would have to be manufactured on an assembly line. The fabric weaving and seat making, the plastic molding and the frame can simultaneously be manufactured in their respective work areas. Following are…

Written exercise Paragraph 1 Iron phosphate, FePO4, has a very similar structure as quartz. Quartz has a trigonal lattice structure with space group P3121 (group no. 152). Similarly, at temperature below 980K, iron phosphate exists as α-FePO4, which also exhibits trigonal lattice structure with space group P3121 in which iron, phosphate and oxygen occupy Wyckoff position 3a, 3b and 6c respectively. In quartz, every silicon atom is connected to four oxygen atoms to form a network of…

Figure 7. TA flux across membranes prepared with different proportions of AC:Pectin (CP2 and CP3) and DBS concentrations. Mechanical properties are very important parameters in membranes and coatings. These properties determine the homogeneity, resistance and film forming capacity of the coating. In figure 8 we represent some of the more important mechanical parameters obtained by mean tensile test. Figure 8. Mechanical parameters of the EC:Pectin membranes obtained with CP2 and CP3. In the…

structures that in turn lead to distinctive flat surfaces, or faces. The faces intersect at angles that are characteristic of the substance. When exposed to x-rays, each structure also produces a distinctive pattern that can be used to identify the material. The characteristic angles do not depend on the size of the crystal; they reflect the regular…

Choosing A Textile Motorcycle Jacket - If, like me, you believe the pros of owning a textile motorcycle jacket far outweigh the cons, there are a couple of things you should keep in mind when choosing the one for you. Denier Rating - The denier rating of a textile motorcycle jacket denotes the weight of the strands used to create the garment. So if a jacket has a high denier rating, it will be thicker and more durable than a jacket with a low denier rating. Or, at least, that’s how it’s…

Metallic bearings Steelair’s bimetallic bearing represents advancement in bearing technology and it can be assembled, accustomed or soldered into place. Along with high load capacity and good fatigue properties, it is also an excellent wear-resistant material. The bimetallic bearing is the composite of low friction copper alloy and is perfect for use when provided with excellent requisite strength and the finest carrying capacity by means of derived remains and secondary wedging technology. It…

“Consumers are wasting billions of dollars a year on billions of gallons of bottled water in large part because advertising spin has led them to believe that water in a bottle is safer or better than tap water” (“Why Tap Water Is Best”). Tap water against bottled water is a tremendous feud today in our environment. An ongoing argument is occurring between which one helps your environment, pocketbook, or health. A more variety of studies shows that tap water is better than bottled water. To…
