Which cement is better for tiles work, OPC or PSC??

While OPC or Ordinary portland cement is considered the best for regular construction needs, PSC or portland slag cement

is more suitable for tile work. The reason being PSC speaks of high flexural strength. Its application lowers the risk of cracking, promises workability, durability, and superior finish that makes affixed materials stay intact for years to come. The near-white color slag permits you to achieve a lighter color for exposed spaces between the tiles and gives the wall a fair-faced concrete finish.
