MATERIAL TESTING

The laboratories in KHRI facilitate various material tests associated with infrastructure development which cater to preconstruction, post construction, and forensic requirements. It includes tests on building materials and pavement materials like cement, concrete, steel, bitumen, soil, aggregate etc. This material testing service is open to both Government and non-government organizations, who make use of this facility at affordable rates. All testing activities at KHRI are managed with the help of software-based Laboratory Information and Management System (LIMS) with the utmost quality control. KHRI Laboratories also have NABL Accreditation.
