Testing

A test engineer is a professional who determines how to create a process that would best test a particular product in manufacturing and related disciplines, in order to assure that the product meets applicable specifications. Test engineers are also responsible for determining the best way a test can be performed in order to achieve adequate test coverage. Often test engineers also serve as a liaison between manufacturing, design engineering, sales engineering, and marketing communities as well.

Building Material

Cement

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.

Admixture

Admixtures are added to the concrete, in addition to cement, water, and aggregate, typically immediately before or during the mixing process. Admixtures can be used to reduce the cost of building with concrete or to ensure certain required properties or quality of the cured concrete.

Building Lime

Pure lime is produced either as putty or a powder. The powder is also known as Builders’ lime because it is generally available from builders merchants and is used by builders to gauge cement mortars, Hydrated lime, or dry hydrate, which is confusing because all lime is hydrated by virtue of having had water added.

Marble (Block/ Slab/ Tiles)

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.

Granite

Granite is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.
