Construction Materials and Testing is essential when you undertake a project for
building a new structure or amending & improvising an existing structure. This type
of testing service helps you determine the quality, safety, efficacy, and endurance of
the materials used for the project.
The services involved in a comprehensive CMT process greatly depend on the project,
the land, and the scope of services. Various agencies, such as DOT, ACI, and the EPA,
offer certification for specific CMT knowledge.
On-site Testing:
- On-site or field testing takes place on the site. This type of testing includes factors
that can be evaluated through visual inspection and/or non-destructive techniques
such as air, moisture content, and more.
Soils
Concrete/Asphalt
Steel
Masonry
Timber
Laboratory Testing:
1. Testing of Rocks:
Rocks are the most common materials used in construction. Some foundations
are even made with rocks. Thus, the stones used in construction must meet the
required quality standards. Igneous, sedimentary and metamorphic are the
three types of rocks found. A civil engineer would perform various tests to
understand what type a particular rock is, and check its electrical resistivity – a
crucial factor in countering electric shocks. Testing of rocks also includes
durability and slaking tests to ensure the rocks won’t disintegrate when
exposed to moisture.
2. Testing of Bricks:
Bricks are known as load-bearing materials that support your construction. The
bricks utilized in construction need to be hard and durable because poor quality
bricks will disintegrate a structure within a couple of years or even months. To
ensure low-quality bricks aren’t used in construction, a civil engineer needs to
send the sample to a construction materials laboratory. This will help determine
whether or not the bricks are durable enough to withstand natural calamities.
3. Testing of Soil:
Soil testing in civil engineering revolves around the in-depth analysis of the
soil to check if it has a dry or moist base. Depending on the result, the
engineer can decide whether to continue or stop the construction. Without soil
testing, the foundation can sink or entirely deteriorate, leading to the collapse
of the entire structure. Thus, the initial soil investigation reports must meet the
subsurface soil examination done in the laboratory.
4. Testing of Cement:
5. Testing of Concrete:
Modern structures cannot be constructed without the use of concrete. There are
multiple concrete tests that a civil engineer would perform to ascertain the quality
of the concrete and determine if it is ideal for use. A slump test is carried out to
check if the concrete complies with the mix design. Another comprehensive test
is done to check the overall strength of the concrete, which gives a clear picture
of possible cracks. Later, the durability of the concrete is examined by the water
permeability test.
6. Testing of Aggregates:
Aggregates are used for pavement construction. The load transfer capability of
pavements is influenced by aggregates to an extent, due to which it is essential to
test them thoroughly before application. They are tested for strength, toughness,
hardness, water absorption, and shape. This can be done through tests such as:
