CMT Module 1 Flashcards
(54 cards)
commercial testing
materials are already existing. The type of test has already been specified. The objective of this is to determine if these materials comply with the given technical specifications and will fall within the required parameters.
scientific testing
materials are tested to obtain their vital and beneficial properties and determine how it can be advantageous in building a certain structure.
materials research
from the word itself, researches are being conducted for existing equipment to have better understanding of its usage. For new materials, properties are being analyzed. Also, quality standards and procedures are being developed.
Experimental/Experimentation
this is when the result is uncertain that new insight are to be gained
Testing
this is more defined procedure which are the limits and results are clear
Destructive Testing
materials are being tested up to its breaking point or until the material fails. It is said that this testing procedure is much easier to conduct because it results to more information regarding the material properties.
Non-Destructive Testing
this is the exact opposite of destructive testing. It is commonly used when the materials to be tested are still in service.
Precision
tells how close the measurements are to each other. For example, if you measure a certain object repeatedly and the numbers you have obtained are very close or almost the same to each other, then it can be considered as precise.
Accuracy
tells how close the measurement is to its true value. For example, your actual height is 5’0”. When you used a tape measure to know your height and the value you get is also 5’0”, then you can consider this as accurate.
Specification
a precise statement of a set of requirements, to be satisfied by a material, product, system or service. It is desirable that the requirements, together with their limits, should be expressed numerically in appropriate units.
standard specification
for a material is the result of agreement between those concerned in a particular field and involves acceptance for use by participating agencies.
Standardizing Agencies and Relevant Standards
Turkish Standards Institute (TSE)
American Society for Testing and Materials (ASTM)
International Standards Organization (ISO)
European Committee for Standardization (CEN)
Linear Traverse Machine
When mixing concrete, air voids commonly occur. This equipment facilitates the counting of voids in concrete.
Compression Machines
This equipment is used to test the behavior of a concrete sample while compressive loads are being applied on it. Some of the results obtained are its compressive strength, yield strength, ultimate strength, elastic limit, etc.
Slump Test Equipment
This equipment is used to measure the consistency of the concrete before it sets. The workability of the concrete can also be determined through this test. An improperly mixed batch can be known with this procedure.
Sieve Shaker
This equipment is used to analyze the particles of sample aggregates as it is sifted according to its sizes.
Liquid Limit Testing Equipment
This equipment determines the water content at which soil changes from a liquid to a plastic state.
Plastic Limit Testing Equipment
This equipment determines the water content at which soil changes from a plastic to a semi-solid state.
Shrinkage Limit Testing Equipment
This equipment is used to indicate how much moisture will be lost before the sample undergoes significant volume change.

Industrial Construction
It refers to the building of large scale manufacturing, processing and chemical plants or utility generation installations.
CONSTRUCTION DOCUMENTS (CD)
Construction Drawings
Construction Specifications (Master Format)
Construction Drawings
Sometimes referred to as working drawings, shows the dimensional relationships between all aspects of the building: their form, sizes, and quantities.
These drawings, usually computer generated, with dimensions, indicating the physical relationship between components – their location, range, the materials used, and their colors and texture.
The drawing are the basis on which the contractor generates cost estimates and are used to guide the actual construction of the building on the site.
