The Hydraulics lab is equipped with adequate facilities to offer experiments on Fluid Mechanics and Open Channel Flow. Two of its major apparatus are the Hydraulic Bench and the Flume, both offering testing options and quality comparable to the highest standards.

At present, the experiments performed using the Hydraulic Bench include flow measurements through orifice, mouthpiece, V-notch and Venturimeter as well as thedetermination of the coefficient of velocity by coordinate method.

The experiments using the Flume are the flow measurements through a broad-crested weir, sharp-crested weir, sluice gate and Parshall flume. Besides it is used for the demonstration of hydraulic jumps.

In addition to the two major apparatus, the lab also has the apparatus for determining the Center of Pressure and for verifying Bernoulli’s theorem.

    

 

Engineering Materials Lab

Structural construction in Bangladesh as well as in many parts the world is still largelydependent on concrete. Despite the use of steel, masonry, timber etc., concrete is still the most widely used construction material for building structures in our country and is used worldwide. Therefore the materials primarily tested in the Engineering Materials Laboratory in the Department of Civil Engineering (CE) of UAP are concrete itself or its constituents (i.e., cement, fine aggregate and coarse aggregate).

The Engineering Materials lab, operating since Spring 2001 was one of the earliest labs set up in the CE department. Over the years, it has grown significantly in size, scope and apparatus. Currently, the lab is being used for offering sessional courses to 2nd year students, as well as for research by final year students and the departmental faculty.

The experiments on cement performed in this lab include the normal consistency, initial setting time of cement and test for compressive and tensile strength of cement mortar.

The tests on aggregate include the sieve analysis, specific gravity, absorption capacity of fine and coarse aggregate, unit weight and void test as well as Los Angeles abrasion test of aggregates.

Concrete cylinder and cube specimens are also used for tests of strength (compression and tension) as well as workability (slump). The lab is also equipped with adequate curing facilities for the concrete specimens. The stress-strain diagrams of the concrete specimen are also drawn using measurements from the strain gages. In addition to concrete crushing tests, non-destructive tests are also performed using the Schmidt Hammer.

The Universal Testing Machine (UTM) of this lab was the first of its kind built in Bangladesh and has produced accurate and reliable results for academic and research purposes for the last ten years.

 

Transportation and Traffic Engineering Lab

The CE department’s Transportation and Traffic Engineering Laboratory has been operating since the Spring 2003 semester. The primary purpose of this lab was to offer the sessional course on Transportation Engineering to 3rd year students, but it is equipped with research facilities for the students and faculty.

Since Traffic Engineering and materials are parts of the broader field of Transportation Engineering, they have both been included in the lab. In addition to testing of transportation materials like aggregate, sub grade and bitumen, the departmental students and faculty also work on traffic capacity measurements.

The sessional course on Transportation Engineering includes about fifteen tests on TrafficEngineering and Transportation materials. The lab tests on Traffic Engineering.

include the determination of roadway capacity and saturated flow at traffic signals. The tests on aggregate include the aggregate impact value, aggregate crushing value, ten percent fines value, flakiness index, elongation index and angularity number.

Tests on bituminous materials include determination of specific gravity, penetration and solubility. Besides, the Marshall method of mix design and the California Bearing Ratio (CBR) test of sub-grade soils are also performed in the laboratory.

The lab is equipped with adequate instruments like Impact testing apparatus, Marshall method apparatus, CBR apparatus, standard penetrometer, solubility measuring accessories, traffic counter and various necessary accessories.

  

Geotechnical Engineering Laboratory

The stability and proper functioning of most Civil Engineering structures depend onthe foundation and the soil it is built upon. The available variety of soil is so wide and their features are so different that it is essential to know their physical and mechanical properties by a number of tests. These include the physical appearance, texture, density, permeability, strength and other important properties. The tests in the department’s Geotechnical Engineering Lab are aimed at determining these properties.

The Geotechnical Engineering lab has been operating since Spring 2001. Currently it offers a sessional course on Soil Mechanics to 3rd year students, which includes ten experiments on various geotechnical properties. The lab tests on general properties of  the soil include the field identification tests, the Atterberg’s Limit tests, specific gravityand relative density tests, compaction test, grain size distribution by sieve analysis and hydrometer analysis of soil sample. Permeability test of soil is also performed using the permeability testing apparatus.

Strength tests performed in the lab include the Direct Shear test and the Unconfined Compression test. Both the instruments are equipped with strain gages in order to get the load-deformation or stress-strain curves.

In order to perform these tests properly, the lab has the necessary devices like hydrometer, deflocculating agent, drying oven, desiccator as well as special tools like the consolidation unit, direct shear machine and unconfined compression machine.

Environmental Engineering and Chemistry Laboratory

The Environmental Engineering Laboratory offers sessional courses, as well as research and testing facilities for the students and faculty. Since the department has traditionally put extra emphasis on environmental courses, this lab was established very early in the department, and has been operating since Fall 1999. The lab currently offers about fifteen experiments on Environmental Engineering, mainly of water quality and sound pollution.

The experiments on water quality include the comparison of color, measurement of pH, turbidity, carbon-dioxide, total solids, dissolved solids, suspended solids, alkalinity, hardness, chlorine concentration, iron concentration, chemical coagulation, residual chlorine and chlorine demand.

The tests on sound pollution include analysis of the combined effect of noise and analysis of noise protection efficiency. The lab is equipped with apparatus like the pH meter, color comparator, turbidity meter, digital sound level meter, Arsenic measuring kits and other necessary devices.

In addition to offering sessional courses, results from the lab have been used for research works on water quality assessment, sound pollution and Arsenic measurement.

The tests performed in the Chemistry lab include standardization of different solutions (of sodium hydroxide, hydrochloric acid, sodium thiosulphate, potassium permanganate etc.) by standard solutions (of oxalic acid, sodium hydroxide, sodium carbonate, potassium dichromate, sodium oxalate etc.), determination of metal contents (copper, ferrous ion, calcium etc) in various solutions.

The laboratory performs monthly water quality testing in the department. To see these reports please follow archive below.
