2010-5-28 By Adam D. Neuwald. Two of the most commonly specified requirements for concrete used in the manufactured concrete products industry are the design compressive strength (f’ c) and the maximum water-to-cement ratio (w/c).These two values are inversely related, which means that as the water-to-cement ratio increases, the compressive strength decreases.

2021-3-14 An octant, also called "reflecting quadrant", is a measuring instrument used primarily in navigation.It is a type of reflecting instrument that uses mirrors to reflect the path of light to the observer and, in doing so, doubles the angle measured. This allows the instrument to use a one-eighth circle arc to measure a quarter circle or quadrant.

2021-3-19 The drilling bit has to be reinforced at its outer parts to resist against the impacts caused by the direct contacts with hole walls. Many methods can be used to protect the bit, one method is hard facing the bit with a tungsten carbide layer at the outer parts, also a series of tungsten carbide inserts can be pressed at the same parts concerned by the impacts and wears.

2021-3-18 Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.. In addition to melting the base metal, a filler material is typically added to the
