 Open Channel Hydraulics lab

 The open channel hydraulics lab of Civil Engineering Department has been designed for teaching open-channel flow as well as for research purposes. The flume available in this lab (0.4 m by 0.6 m in cross-section and 7 m in length) could accommodate a maximum flow rate of 70 lit/sec. The flume includes basic instruments which help undergraduate students in boosting their understanding of basic properties of free flows, and is frequently used in teaching subjects arising in the hydraulics course. The flume also meets standards required in conducting research and industrial projects for more advanced applications.
 The tests which are demonstrated for undergraduate students fall in the following four categories:
1) Open-channel flows: general behavior of free flows, including how flow responds to the changes in the width as well as in the floor level of the channel.
2) Sluice gate: how flow properties are affected in passing through a sluice gate, and how to calculate flow rates under free and submerged conditions.
3) Weirs: flow rate measurement by rectangular, triangular,broad-crested, and Ogee weirs.
4) Hydraulic jump: formation of hydraulic jump, and how to estimate and control the head loss which is induced by the jump.
Construction and building material laboratory
The construction material laboratory was established in 2007 at civil engineering department. This lab is a joint partner of the Isfahan university central laboratory (http://www.centlab.ir). Most of tests on the construction materials such as concrete, brick, cement, gypsum, mortar, aggregate and other common materials can be done in this lab. Additional tests which may be required are done by the central lab including, XRD (X Ray Diffraction), XRF (X Ray Fluorescence Spectroscopy), NMR (Nuclear Magnetic Resonance spectroscopy) and other required tests.

Following is the list of some tests which can be done in the lab.

Bricks relevant tests such as:
Physical properties
Compressive strength
Flexural strength
Freezing and thawing

Gypsum relevant tests such as:
Physical and mechanical properties
Compressive strength
Flexural strength

Concrete and cement mortar relevant tests including
Compressive strength
Tensile strength
Flexural strength
Abrasive strength
Physical properties of sand aggregate
Workability tests (different types of concrete)
Cement relevant tests

Geotechnical Engineering Laboratory

The geotechnical engineering lab was established in 2007 for educational as well as research purposes. As part of their curriculum, undergraduate students use this lab to conduct fundamental tests in soil mechanics. Special services are provided for Masters and PhD students to carry out their experimental research projects in the general areas of rock and soil mechanics. The lab also accepts requests from industry to conduct particular experimentsrequired in industrial projects.
A summary of the experiments which can be conducted in the lab is as follows.

Physical properties of soil
v grading by sieve and hydrometer
v bulk density
v specific gravity
v sand value
v permeability (constant and falling head)
v Atterberg limits (shrinkage, plastic and liquid)
v Soil dispersion (pinhole test)
v Soil compaction (dry density-moisture content relationship)
Mechanical properties of soil
v Direct shear box (small 10 cm×10 cm and large 30 cm×30 cm size)
v Triaxial shear strength (38 mm dia. Hoek cell)
v California bearing ratio (CBR)
v Unconfined compressive strength (UCS)
v Compaction/swelling
In-situ mechanical properties of soil
v Standard Penetration Test (SPT)
v Plate Loading Test (PLT)
Mechanical properties of rock
v Crushing and impact value for aggregates
v Triaxial shear strength (38 mm dia.) (UU, CU, CD)
v Unconfined compressive strength (UCS)
v Rock core sample preparation (coring, lapping)
In-situ mechanical properties of rock
v Point Load Index Test
v Field shear box on saw cut and natural joints
