The major pieces of equipment include the sieve shakers, sample splitters, curing tank, drying ovens, and compression machine. Students learn the fundamentals of concrete mix design and testing in this lab. Tests are run on aggregates as well as on the freshly-made and hardened concrete. Students can measure the effect that different aggregate gradations.

- Concrete forms
- Capping equipment
- Sieve shakes
Students study the characteristics and behavior of soils as they relate to the design and construction process. Topics include origins of soils, permeability (The flow of water through a soil), subsurface stresses, shear strength, consolidation and settlement.
Some of the Learning Objectives and Goals of this lab Include:
- Identify and calculate basic physical and gravimetric properties of soils such as density, specific gravity, void ratio and porosity
- Classify Soils using index property indexes such as liquid limit, (the point at which a soil liquefies), Plastic Limit, (the water content where a soil will begin to exhibit plastic behaviors) and gradation, (Particle Size Distribution).
- Identify and conduct appropriate laboratory testing to understand the role of subsurface exploration of soil samples to predict the behaviors of in-situ soil deposits
- Acquire, organize and analyze laboratory data
- Provide an opportunity for students to improve their written and verbal technical skills
The major pieces of equipment in this laboratory include a triaxial machine, two direct shear machines, two unconfined compression machines, four consolidometers, a data collector, and sieve shaker. Tests on field-obtained soil samples can be performed to characterize and classify soil and to determine the strength, settlement, and drainage characteristics of soil deposits, information which is essential to the design of shallow and deep foundations, embankments, retaining walls, and base courses for highways.
Description of Major Equipment
- Direct shear machines
- Traxial machine
- Load frames for unconfined compression and Marshall Mix design
- Atteberg limit equipment
- Specific gravity eg.
Before students can design concrete or mortar, they have to understand the materials with which they are working. Here, students will define the difference between coarse and fine aggregate as well as the difference between fine aggregate and soil.
Students perform specific ASTM tests including:
- Moisture content
- Specific Gravity
Students will do final compressive strength tests on their concrete to determine if it meets the specification for which they designed. In order to do this they will cap and break their concrete cylinders.
Capping (ASTM 617) is done to give the cylinder a perfectly flat surface to insure a good break.
The strength of the cylinder is then recorded in PSI and students will then organize and prepare all data for their final concrete reports.
This laboratory houses a variety of typical laboratory analytical equipment and assorted glassware. There are incubators for B.O.D. testing and incubating biological samples, and a water distillation column and 12 bench microscopes. This lab houses an atomic absorption spectrometer with data acquisition unit and a gas chromatograph with mass selective detector.
Descriptions of Major Equipment
- Bench scale demonstration units
- Perkins Elmer Analyst 300
- Hewlett-Packard 6890 gas
Equipment in this laboratory is used to demonstrate the basic principles of hydraulics and fluid flow in both open channels and closed conduits. Students learn the concepts of buoyancy, velocity of flow, energy losses in bends and restrictions, sediment transport and pump efficiency. A large bench is a reservoir with a pump to circulate water. Individual experiments can be hooked up to these, allowing students to have separate workstations. Of particular note are the two five-meter flumes.
- 5 meter flumes with accessories
- Basic hydraulic benches with accompanying experiments
- Sedimentation transport channels
- Fluid friction measurement units
- Pipe network apparatus
- Series and parallel pump apparatus
