Civil Engineering Laboratories
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.
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:
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.
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:
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.
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.
