UET Professor wins Prime Minister Award for Research work

LAHORE: Professor Dr Zahid Ahmed Siddique, Head of Department of Civil Engineering, University of Engineering and Technology, won Prime Minister Award for conducting research on “Bond strength of Model Steel and other steel”.Professor Dr. Zahid Ahmad Siddique was also given cash prize for the research work he completed in record time. He conducted the study to evaluate bond performance of Model Steel reinforcing bars. The study was carried out according to ACI408.2R-92 pullout tests were conducted on fully automatic strain controlled universal testing machine of Shimazu, Japan. The data was recorded by data acquisition system of machine at every 50 milli second.

The pullout samples were prepared with normal strength concrete having compressive strength 30 MPa. The recorded slump value was 85 mm. The embedded length was selected to be 12 d.These pullout samples were put in a specially designed assembly to grip them in testing machine. This assembly has the arrangement to eliminate any eccentricity during casting of the samples.

The tests were conducted after 28 days.State of the art strain controlled fully computerized universal testing machine was used for the tests. The machine has its own data acquisition system. It recorded the data at every 50 milli second time interval. More over being servo controlled it also provided whole post peak bond behaviour which is not possible with load controlled ordinary testing machines. – Onlinenews
