Tiles and Natural Stone

The ceramics and natural stone section specialize in the tests of dimension stone, marble & granite stone, Porcelain, terrazzo and ceramics tiles using modern equipment according to international specifications like ISO and ASTM, the tests which are performed are physical, chemical and mechanical such as modulus of rapture, flexural and compressive strength of natural stone, water absorption of ceramics and stones, staining of stones and ceramic, anchorage strength of natural stone, slip resistance of ceramic tiles, Pull off test (Adhesion Bond strength) for wet cladding and tiles adhesive materials, detection of Voids behind the stone ( Honeycombing in concrete) in wet cladding using Ultrasonic Device, Structural Performance of Exterior Dimension Stone – Dry Cladding Systems by Uniform Static Air Pressure Difference.. etc.
