ACTIVITIES

OF LABORATORY OF NON -METALLIC MATERIALS Activities of laboratory are related to the testing of cement, lime, gypsum,

asphalt, fresh and hardened concrete, concrete structures, concrete pipe,

curbs and other prefabricated elements, plaster, clay, brick products, and

other building materials.

In addition to investigation of commercial construction materials, our

laboratory is engaged in examining various natural and waste materials,

byproducts from the production of various industries and finding theirapplication in construction and production of new materials, as well as

research aimed at increasing the durability of concrete structures.
