Engineering Materials Laboratory


ENGINEERING MATERIALS LABORATORY

This Laboratory is housed in the Basement – 1 of the SAC Building of North South University. The floor area of this laboratory is 236.80 sqm with enough space for mixing materials and casting concrete members. It is well equipped for carrying out routine tests of concrete and concrete making materials. The major equipments including the compression testing machine are made in Italy. Facilities are also available for cutting concrete core and testing in the laboratory.This laboratory is extensible for UG/PG teaching and research purposes.
