Introduction to Concrete technology lab

Introduction

The behavior and properties of structural materials, e.g. concrete, asphalt and steel can be better understood by detailed, well-designed, first hand experience with these materials. The students will become familiar with the nature and properties of these materials by conducting laboratory tests. These tests have been selected to illustrate the basic properties and methods of testing of cement, aggregates, paste, mortar, concrete, asphalt and steel. Test procedures, sometimes simplified because of time limitation, are mostly those outlined by the Indian Standards.

Course Objectives

1. To prepare the students to effectively link theory with practice and application and to demonstrate background of the theoretical aspects. 2. To prepare the students to generate and analyze data using experiments and to apply elements of data statistics. 3. To prepare the students to have hands on experiments and to have exposure to equipment and machines 4. To prepare the students to solve problems including design elements and related to their course work. 5. To encourage the students to use computers in analyzing the data. 6. To emphasize the knowledge and application of safety regulations.

Student Responsibilities

1. In the very beginning of the laboratory work, the students will be organized into groups. For this reason, regular attendance is strictly required. 2. Every laboratory session is divided into two parts. In the first part, the instructor will be lecturing on the test objective, procedure and data collection. In the second part, the students, organized in groups, are required to conduct the field work. In order to perform the field work within the assigned period, and to gain the maximum benefit from the field work, the students must familiarize themselves with the purpose, objective, and procedure of the experiment before coming to the laboratory. Relevant lecture notes and laboratory manual should be studied carefully and thoroughly. 3. At the end of the test, every group should submit a draft sheet of the data collected for approval by the instructor. 4. It should be understood that laboratory facilities and instruments are provided to enhance the learning process and to give first hand experience of surveying. 5. The instruments and tools must be properly cared and cleaned during and after every laboratory

session. Also, students should always take precautions to avoid any possible hazards. Students must follow laboratory regulations provided at the end of this section.

Report Writing

Every student is required to submit his own separate report for each test conducted. Reports should be writing on 8½ x 11 in. high-quality paper. In general, the reports should be arranged in the following order:

Laboratory Regulations

1. Make sure that you know the location of Fire Extinguishers, First Aid Kit and Emergency Exits before you start your experiments. 2. Get First Aid immediately for any injury, no matter how small it is. 3. Do not wear loose dress 4. Always use close shoes (i.e. safety or boots) 5. Do not play with valves, screws and nuts 6. Do not try to run and operate any machine without permission and knowledge of the lab. personnel
