Tile Abrasion Testing Machine: Tile Abrasion Testing Machine (Ref. Standard IS:1237-1980, 1706-1972) with abrasive power.

Tile Flexural Strength Testing Machine: Ref. Standard IS: 654, 1237-1980); for carrying out transverse strength tests on cement concrete flooring tiles and clay roofing tiles- with facility for hand operation.

Linear shrinkage: Shrinkage limit is the maximum water content at which a reduction in water content does not cause an appreciable reduction in volume of the Soil Mass. At shrinkage limit, on further reduction in water, air enters in to the voids of soils and thus keeps the volume constant. The apparatus can be used to determine shrinkage limit and to calculate other shrinkage factors like shrinkage ratio, shrinkage index and volumetric shrinkage. Complete set consists of one each following parts and accessories.: Porcelain evaporating Dish. Brass shrinkage dish. Glass cup. Perspex plate with three metal pronge. Flexible spatula. Glass measuring cylinder 25ml. Steel straight edge.
