CE31 2 Construction Materials an Testin d g by: CE Faculty CE31 2 Week 1: Day 1 Introduction to Construction Materials & Testing CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Construction Materials - are any materials that used for construction - the success of a construction project also lies on the materials used especially when the materials are tested against time. - the durability of the materials is one of the relevant factors to be considered. CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Construction Materials manufactur naturally ed products occurring such cement, materials such as rebars, pipes, stone, timber, sand, tiles, ceramics, rock, soil, etc. glass, paints, etc. by: Engr. Vera Karla CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Materials Testing - is performed for a variety of reasons and can provide a wealth of information about the tested materials, prototypes or product samples. The data collected during testing and the final test results can be very useful to engineers, designers, by: Engr. Vera Karla CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Reasons why material testing is important 1. Meeting requirements of regulatory agencies 2. Selecting appropriate materials and treatments for an application 3. Evaluating product design or improvement specifications 4. Verifying a production process by: Engr. Vera Karla CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Factors Determining the Choice of Proper Material for a Structure A. Strength, Rigidity & Durability Requirements 1. Permanent loading → Creep Strength (Creep strength is the maximum stress endured by a material for a specific period of time without extreme deformation.) 2. Repeated loading → Fatique Strength (Fatigue strength is the highest stress that a material can withstand for a given number of cycles without breaking) by: Engr. Vera Karla CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Factors Determining the Choice of Proper Material for a Structure A. Strength, Rigidity & Durability Requirements 3. Impact loading → Toughness & Resilience (Toughness is the property due to which the material can withstand impact loading without fracture. Resilience is the property due to which a material can store energy without having permanent deformation) 4. Surface loading → Hardness & Resistance to abrasion (Hardness is measured by poking a point into the test material and measuring depth of penetration. Abrasion resistance is measured by rubbing something against the test material and measuring how much material is removed) by: Engr. Vera Karla CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Factors Determining the Choice of Proper Material for a Structure B. Environmental Requirements 1. Temperature Change→ coefficient of thermal conductivity (The thermal conductivity of a material is a measure of its ability to conduct heat) 2. Moisture movement → permeability (Permeability is defined as the volume of a fluid of unit viscosity passing through a unit cross section of the medium in unit time under the action of a unit pressure gradient) 3. Chemical effects → chemical composition (Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products) by: Engr. Vera Karla CE312: Construction Materials and Testing Introduction to Construction Materials & Testing Factors Determining the Choice of Proper Material for a Structure C.
