  TERRAZZO TILES

Terrazzo is a composite material, poured in place or precast, which is used for floor and wall treatments. It consists of marble, quartz, granite, glass, or other suitable chips, sprinkled or unsprinkled, and poured with a binder that is cementitious, chemical, or a combination of both. Terrazzo is cured and then ground and polished to a smooth surface or otherwise finished to produce a uniformly textured surface.

Terrazzo tiles shall be formed with wet mix of white or white blended with colored cement or white cement with a color pigment added and granular terrazzo aggregates applied through out the tile to provide a monolithic finish. The tiles should be cast in strong moulds to proportion of 300 x 300 mm size with typical thickness of 19 mm with size tolerance of ▒ 0.5 mm.

The terrazzo tiles mix shall be proportioned and admixed with chemical to provide compressive cube strength of 3,000 psi after 28 days of curing and water absorption of less then 1.8 %. Tiles shall be cured and delivered to site without any repair grinding or polishing. After installing and grouting the tiles, grinding shall be done wet by means of a no. 800 carborundum stone.

Filling shall be carried out with neat grout of the some color, as the facing mix and this shall be worked into the surface with a wooden shaper to fill as voids and air holes. Surplus grout shall be removed with a dry cloth. After a minimum period of 24 hours, polishing shall be carried out wet by means of a No. 140 carborundum stone.
