Credits : 3 credits Instructor(s) : Mr. Helmi Khatib and Dr. Ghassan Chehab Office Hours : Dr. Chehab: Bechtel – 4th floor Mr. Khatib: M/T/W/Th from 10:00 to 11:00 am, Irani Building Room 110b Location : Lecture: Irani Oxy Engineering Complex – Room 225 Lab: Geotechnical Lab, Irani Building, Level 1, Room 111 Textbook : “Materials for Civil and Construction Engineers”, M. Mamlouk and J. Zaniewski, Pearson, latest edition References : 1- “Fundamentals of Building Construction: Material and Methods”, Edward Allen & Joseph Iano, 1998 2- Construction: Principles, Materials, Methods”, Harold B.Olin, Walter H. Lewis, Sixth ed., 1994 3- “Civil Engineering Materials”, Second Edition, Shan Somayaji Course Objective: The objective of this course is to introduce civil engineering students to the usage of different construction materials and their applications. Course Outcome: After completion of this course:  Students will be able to measure and/or monitor material properties through standardized experimental protocols.  Students will understand the empirical/mechanistic properties and performance of commonly used construction materials.  Students will understand the importance of professional and ethical responsibilities in selecting proper materials and material characteristics on structural safety and performance.  Students will be able to conduct research on specific issues related to construction materials.  Students will develop their life-long learning skills by conducting studies and reporting results in relation to new or innovative construction materials.  Students will have some practice in performing forensic case studies on structures within a team environment. Attendance Policy: A total of three absences for the semester will be permitted w/o penalty. For every absence beyond the third, 5 points will be deducted from the final course grade. The student may seek to reverse the above, by presenting a petition along with a documented valid excuse explaining the reasons for absences, to the FEA Academic committee. Exam: There will be two written Exams, (30 % each). Lab Sessions: Sessions are divided as follows: 30 min Lecture and 90 min Hands-on experiment Lab Procedures:  The class will be divided into 4 groups; every group is assigned to complete 1 project and submit lab reports.  As a pre-lab duty, the student shall read and understand the corresponding chapter in the textbook.  Each group will cleanup and be responsible for his work area and equipment. 2 Daily assignments, laboratory reports, presentations and drop Quizzes (15 %) Site project - Group work (10 %): Every group of students is required to visit a construction site or a construction material factory (Buildings, roadways, masonry and tile plants, concrete and asphalt plants, quarries), in order to report and record the use of materials in construction, and step-by-step construction procedures. Lab testing term project- Group work (15%)  The performance of students in this project will be evaluated in accordance with several performance indicators (PIs) as outlined below. The performance indicators are designed to measure the level of students’ achievement of ABET Program Student Outcome b “An ability to design and conduct experiments as well as to analyze and interpret data,”  The general PIs are as follows: o PI b.1- Ability (of students) to design an experiment. o PI b.2- Ability to conduct an experiment, and o PI b.3- Ability to analyze and interpret data.
