The interwoven meshwork thereby created eventually consolidates to form a rigid matrix that effectively binds the composite mass: the residual grains of unreacted cement, the crystalline products of hydration and the aggregate material. The hydration of C 2 S occurs at a much lower rate and will only affect the final strength of the set cement.

Magnetic particle testing (MT) is a method for testing magnetizable materials with a minimum of time.Magnetic particles are applied to the object to be tested with a liquid or powder. Inconsistencies are then revealed by a change in the magnetic field, which causes the particles to be aligned differently from the 'good' part of the object.. In this way cracks or inclusions of non-magnetic ...

These drill bits have a brad point tip (also known as a W-point tip) that allows the outside cutting edges of the drill to cut the diameter of the hole before the centre breaks through. This results in the bit not grabbing and producing a very clean hole. It is therefore perfect for drilling into wood and some plastics and for jobs like dowelling.

Hammermill or impact grinding of dry feeds, especially cereal grains, creates particles within the range called "dust", and a dust-collecting system may be necessary to remove this. An excess of dust in the feed may lead to gill disease, a situation where organic matter adhering to gills becomes a nutrient for bacteria or parasites.

The tempering process is an essential stage in heat treatment, especially in very fast cooling, as it brings back ductility. Before we can start the quenching process we need to heat the steel to a high heat. We're talking extreme here- over 1,600° F. Heating to this temperature causes a grain structure called austenite to form.

Richard says hammering across the metal moves it quickly in two directions: length and width. He uses this technique on heavy 6-gauge square wire for cuffs and bangles, but this is also how his spoon handles are formed. Still using a cross-peen hammer, Richard shows how hammering lengthwise along the clay spreads the metal in width only.
