To Calibrate a Pressure Gauge Using a Dead Weight Pressure Gauge Calibrator
A length of tube was connected to the calibrator drain and laid into the channel to prevent spillage of water on the bench top. The calibrator was leveled by the adjusting feel whilst observing the spirit level.Tensile Strength or Tension Test
Tensile strength of a material is the tension stress at which a material breaks or permanently deforms (changes shape) Toughness, Resilience, Poisson's ratio can also be found by the use of this testing technique. This data is plotted as load vs elongation and then converted to engineering stress (load/original area) vs engineering strain (fractional change in length over
To Determine The Shrinkage Limit of Soil
Shrinkage dish, electric oven, mercury, electric balance, sieve#40, spatula and containers. Take a soil sample passing through sieve#40 and add some amount of water in it to form a thick uniform paste. Take the shrinkage dish, weigh it, and put some of the soil mixture in it by spatula, fill it and again weigh it. Place the shrinkage dish in the oven for 24hours.
To Determine the Specific Gravity of Soil
Take at least 25g of soil which has been passed through sieve#4 and place it in an oven at fixed temperature of 105-110C0for 24hours to dry it completely. Clean and dry the pycnometer thoroughly and find its mass (M1). Find the mass (M2) of pycnometer by placing dried soil in it. Add sufficient quantity of water to fill the pycnometer up to the given mark and then
How to Write a Soil Investigation Report | Geotechnical Investigation
Soils reports, also called “geotechnical soils reports” are prepared by a licensed geotechnical engineer or a registered civil engineer experienced in soils engineering. A soils report may be required depending on the type of structure, loads and location of the structure. The report gives understanding of earth conditions affecting a building. They are required in areas
Shock Table Dynamic Test - Structural Dynamics
In the absence of a shaking table, some laboratories have developed simple simulators for dynamic testing of structures. One such kind of a facility, named as the shock table, is installed at the University of Roorkee, India and was developed by Keightly.To Find out the Reaction of Simply Supported Beam
Condition of equilibrium for vertical parallel forces acting on a body is Sum of all the force s should be zero. It should satisfy the principle of moments . If we take moment about a point on moments should be equal to anti clockwise moments.
To Determine Moisture Content of Soil By Oven Drying Method
The water-content determination is a routine laboratory procedure. ASTM has designeated it with a Standard, ASTM D-2216-90 which can be found in “ASTM Standards vol. 4.08”, and also AASHTO T-265, found under “AASHTO Materials: Part II: Tests”. This is a laboratory procedure to determine the amount of water Ww present in a quantity of soil in terms of its
Properties of Paints & Tests Applied on Paints
Important buildings were once designed and put together by master masons who knew how to work with stone, and understood the advantages and limitations of the material. Stone structure should be a combination of structural firmness, technical commodity and aesthetic delight. Ensure proper wall construction. The wall thickness should not exceed 450mm.
Pseudo Dynamic (PsD) Tests - Non Linear Structural Dynamics Techniques
PDT is a substructure technique which includes applying slowly varying forces to a structural model. The motions and deformations observed in the test specimens are used to infer the inertial forces that the model would have been exposed to
Quasi Static Test - What, Why, How
The quasi-static cyclic tests can be used to conduct both basic and proof tests. In quasi-static tests, loads and/ or displacements are applied at slow rates. Normally, such types of tests are carried out to study structural performance of structures and structural
Procedure for Concrete Compression Test
The compression test shows the best possible strength concrete can achieve in perfect conditions. The compression test measures concrete strength in the hardened state. Field concrete samples are prepared, cured and tested according to ASTM standard procedures. Specimens are prepared from concrete taken from
Laboratory Investigation of Hooke’s Law
Prepare the test specimen that is steel bar and find its diameter at tree different places and find its man value. Mark two points 8" a part of 2 ft long steel bar. Insert the bar in jaws for gripping the steel bar and select suitable bar on UTM. Place the steel bar and fix it.
