Preface

In the last couple of decades, there has been a steady and considerable development of civil infrastructure in Pakistan. The development has primarily been in the urban sector, however the rural areas has seen unplanned and un-regulated growth and development. On October 8th, 2005, a devastating earthquake hit the northern part of Pakistan. Following this natural disaster, numbers of initiatives have been undertaken including the joint initiative between Pakistani Higher Education Commission (HEC) and the U.S. National Academies (NAS) to consider effective ways of assisting Pakistan in its research and policy efforts related to post-disaster reconstruction and rehabilitation. With funding provided by the U.S. Agency for International Development (USAID), the NAS organized a team of engineering and technical experts to travel to Pakistan, December 11 – 18, 2005. The specific objective was to explore various means of providing support to the then-recently formed Earthquake Rehabilitation and Reconstruction Authority (ERRA) and other relevant Pakistani organizations as they developed policies and strategies for reconstruction in earthquake-devastated areas. A complementary objective was for the team to identify research priorities that could be supported by specific grants under the ongoing Pakistan-United States Science and Technology Cooperation Program. The key organizations and officials, included ERRA, the Ministry of Housing and Works, HEC, the Pakistan Engineering Council (PEC), the Pakistan Meteorological Department, and USAID staff involved in relief and reconstruction efforts. NAS organized a second visit, June 12-17, 2006, to consult with a variety of Pakistani researchers and officials to share insights as to how such policy and research capabilities might be developed and nurtured both during the next several months and in the longer term. For their report on this second visit, the team members prepared a single document highlighting the top priorities for the short, medium, and longer terms. This report is available from NAS, USA. A global concern is to help build Pakistani capacity to implement a sustainable means of improving overall seismic safety across the entire country. The seismic potential of the region necessitates a permanent, sustained effort supported by indigenous institutions and organizations that can utilize existing and future Pakistani and international expertise to maximize safety and minimize loss of life and property when future earthquakes occur. For building Pakistan’s capacity to implement a sustainable means of improving overall seismic safety across the entire country, it is imperative that technical events such as  workshops and other forums like seminars, conferences, and symposia are conducted to facilitate the exchange of information for the benefit of the construction industry. The Cement Based Materials &Civil Infrastructure (CBM-CI) International workshop is onestep towards the goal of capacity building in Pakistan and this is likely to benefit other developing countries in the region.

The workshop proceedings include three major themes:

· Theme 1 – General

· Theme 2 - Country specific status of concrete construction industry

· Theme 3 - Specialty topics including durability, construction issues for developing countries, and emerging technologies

The papers of first theme are listed in PART 1 of the proceedings. For the second theme, experts from over 20 countries shared overview of status of the concrete construction industry in their respective countries, challenges, and issues facing their industry and the potential advancement anticipated in the next decade in their respective countries. This sharing and exchange of information will collectively be beneficial, as this will foster mutual thinking and collaboration on common issues. These papers are listed in PART 2 of the proceedings. For the third theme, selected presenters focused on specialty topics of interest and enunciated the emerging technologies for the future. These papers are listed in PART 3 of the proceedings.

This workshop proceeding contains 52 papers, out of which 42 papers were selected for presentation at the two day workshop. The papers for presentation were selected based on geographical and other considerations.

At the workshop, in addition to the presentations, working group and discussion sessions were organized to foster group discussions and deliberations. The working groups addressed same set of issues and the group moderators reported the group recommendations to the workshop participants in the closing session. The recommendations of the breakout groups were discussed and deliberated during the panel discussion session by the all the participants of the workshop. In the closing session, Prof. Surendara P. Shah, chair of the CBM- workshop and Dr. Shuaib Ahmad co-chair of the workshop summarized the draft recommendations of the workshop. These recommendations are not included in these proceedings.

The Cement Based Materials & Civil Infrastructure (CBM-CI) International workshop is hosted by NED University of Engineering & Technology under the auspices of the Vice  Chancellor Engr. Abdul Kalam. Chief Guest Dr. Atta-ur-Rahman [Federal Minister and Science and Technology advisor to the Prime Minster of Pakistan] inaugurated the workshop and delivered the opening address. The workshop is sponsored by the American Concrete Institute (ACI), USA National Science Foundation, USA, NED Engineering University, Karachi, Pakistan, and the Higher Education Commission (HEC) of Pakistan. The co-sponsors include Institution of Civil Engineers, Karachi, and the Center for Advanced Cement-Based Materials, Northwestern University, USA.

The local organizing committee organized a one-day cultural tour on December 9th, 2007. The local attractions in the city include Frere Hall, National Museum, Mohatta Palace, Zoological Gardens, Wazir Mansion, Quaid's Mausoleum, Expo Centre, Karachi Golf Course, Beaches. Other attractions within drive distance of Karachi include Chaukundi Tombs (32.9 mi), Thatta (Historical Place, (62.1 mi), Haleji Lake (68.3 mi) and Mohenjodaro (Historical, 121 miles).

The local organizing committee comprised of : Dr. S. F. A. Rafeeqi (Chair), Dr. Sarosh H Lodi (Secretary), Prof. Saeed Ahmed Khan, Dr. Mir. Shabbar Ali, Engr. Faheem Ahsan, Dr. Abdul Samad Khan, Ms. Mah Talat Mirza, Dr. Asad-ur-Rehman, Dr. Asif Ahmed Shaikh, Dr. Muhammad Masood Rafi, Mr. Aftab Ahmad Farooqi, Syed Masood Kazim Jafri, Ms. Arjumand Masood, Mr. Salman Hameed Siddiqui, Mr. Raza Ali Khan, Ms. Farnaz Batool, Mr. Syed Salman Mooben, Mr. Mukesh Kumar, Ms. Saria Bukhary, Ms. Sadaf Qasim, Ms. Tehmina Ayub, Mr. Muhammad Saqib, Mr. Ashar Ahmed, Mr. Uneb Gazder, Ms. Nida Azhar, Ms. Nida Naseem, Ms. Sana Muqeem, Ms. Roomizah Rabail Kharal, Mr. Mohammad Ahmed Rehmatullah, Mr. Farrukh Arif, Mr. Sofia Butt and Ms. Najmus Sahar Zafar.

The workshop organizers would like to thank all sponsors, members of the international scientific/technical committee, and hosts who made this workshop possible. Particular appreciation is extended to the National Science Foundation (Award # 0710807), NED Engineering University (Grant No. Syndicate resolution no. SYN. 143.5, 2007) and Higher Education Commission (HEC) of Pakistan (No. HEC-46.63-Seminars). Special thanks are also extended to all authors for their contributions and cooperation and all the invited participants who contributed to the success of this workshop.

The editor is sincerely indebted to NED University of Engineering & Technology, Pakistan, and especially Dr. Sarosh Lodi, secretary of the CBM-CI International Workshop for invaluable support for the workshop and in producing the workshop proceedings. It is hoped that this workshop will advance the understanding of concrete technology in Pakistan and other developing countries. It is envisioned that the workshop will contribute to capacity building of human technical resource in Pakistan. The workshop is likely to lead to significant improvement in integration of infrastructure development with a better understanding between the Academia, Government, and Industry in Pakistan. The workshop will also assist in promoting international collaborations in education, research, and practice for better design, construction, and maintenance of concrete constructed facilities of civil infrastructure. These proceedings will serve a useful resource for researchers and engineers involved in concrete technology and construction.
