Lesson 1 Flashcards
It helps civil engineering students to identify and classify various materials in construction.
Construction Materials and Testing
What are the associations that provide standard testing procedures of materials in construction?
- American Society of Testing Materials (ASTM)
- American Association of State Highway and Transportation Officials (AASHTO)
Enumerate the importance of study of construction materials and testing.
- It helps civil engineering students to identify and classify various materials in construction
- Be able to state the use of construction materials by applying sampling and testing to determine the properties and suitability of the materials needed for the construction work
- Identify the testing methods and equipments applicable for sampling and testing of materials.
- Proper handling, storing, and preparing materials for testing
- Carrying test of materials conforming to the standard procedures of materials based on ASTM and AASHTO.
What are the basic concepts of a civil engineer?
- Design
- Construction
- Supervision
- Safety
- Maintenance
What are the classification of materials based on their chemical composition?
- Organic Group
- Inorganic Group
These are group of materials that contains carbon as the basic element and includes materials like timber, plastics, asphalt, bitumen, etc.
Organic Group
These are group of materials that contains the siliceous materials essentially containing silica, calcareous and argillaceous materials like clay. Some common building materials are metals: elements like iron, copper, etc. and alloys of different elements.
Inorganic Materials
Inorganic materials contains the __________ essentially containing silica, calcareous and argillaceous materials like clay. Some common building materials are metals: elements like iron, copper, etc. and alloys of different elements.
silicieous materials
Classification of Materials based on their use and function.
- Solid Building Materials
- Binding Materials
- Finishing Materials
- Insulating Materials
These materials are categorized as solid in terms of physical form and mostly they are used to bear loads such as stones, bricks, etc.
Solid Building Materials
These are materials that binds two or materials such as cement (siliceous), lime (calcareous), clay (argillaceous), bitumen (organic), etc.
Binding Materials
Cement - Siliceous
Lime - Calcerous
Clay - Argillaceous
Bitumen - ____________
Organic
Cement - Siliceous
Bitumen - Organic
Clay - Argillaceous
Lime - ____________
Calcareous
Cement - Siliceous
Bitumen - Organic
Lime - Calcareous
Clay - ____________
Argillaceous
Bitumen - Organic
Lime - Calcareous
Clay - Argillaceous
Cement - ___________
Siliceous
These are materials that are used for decorative or finishing purposes such as paint, varnish, distemper, etc.
Finishing Materials
These are materials used for insulation purposes such as rock wool, glass wool, expanded clays, etc.
