GPH Ispat Limited, the leading rebar manufacturer in Bangladesh, and the Public Works Department (PWD) jointly organised a seminar titled "Knowledge Sharing Seminar" at the latter's office in Dhaka recently.

Mohammad Shamim Akhtar, chief engineer of the PWD, attended the seminar as the chief guest, said a press release.

Akhtar stated, "GPH Ispat has demonstrated its sense of responsibility by investing in research in the construction sector. Their joint initiatives with universities have set an example. It is essential to continue such research activities."

"More companies like GPH should step forward to enhance efficiency in the use of construction materials in future building projects," he added.

The seminar highlighted the results of collaborative research involving the application of high-strength rebar B600D-R and optimum concrete in RCC building design.

The discussion focused on how high-strength rebar B600D-R contributes to cost-effective and efficient RCC construction. Additionally, the seminar emphasised the eco-friendly nature and sustainability potential of "Rebar Grade B600D-R".

Two research papers were presented during the seminar.

Md Kamruzzaman, sub-divisional engineer of the PWD, demonstrated how the use of high-strength rebars can be highly effective in RCC building design.

"High-strength rebars reduce rebar congestion and significantly lower construction costs," he said, adding that the use of such rebars contributes to reduced carbon emissions and greenhouse gases, supporting sustainable development.

The second paper was presented by Md Zahid Hasnain, who explained the strength compatibility of the desired concrete with high-strength rebars, and discussed various aspects of using these rebars in construction.

Mohammed Almas Shimul, additional managing director of GPH Ispat; Raquib Ahsan, professor at the Bangladesh University of Engineering and Technology; Syed Fakhrul Ameen, former professor; and AH Mohammad Motiur Rahman, former additional chief engineer of the PWD, were present.

Md Ahsan Habib, former chief engineer of the Public Works Design Division, and Mohammad Abu Sadeque, former director general of the Housing and Building Research Institute, along with additional chief engineers, executive engineers, superintending engineers, and other senior officials from various departments, were also present.
