Moment Distribution Method of Structural Analysis

Moment distribution method offers a convenient way to analyse statically indeterminate beams and rigid frames.In the moment distribution method, every joint of the structure to be analysed is fixed so as to develop the fixed-end moments. Then, each fixed joint is ...

How to Improve Soil Properties

Soil improvement in its broadest sense is the alteration of any property of a soil to improve its engineering performance such as strength, reduced compressibility, reduced permeability, or improved ground water condition. This may be either a temporary process to permit ...

Charpy Impact Test

The Charpy impact test is performed to evaluate the resistance of the metal to breakage by flexural shock or impact load according to standard test method ASTM D6110.

Penetration Value of Bitumen -Determination for Road Construction

Penetration value test on bitumen is a measure of hardness or consistency of bituminous material. A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100. Penetration value is the vertical distance traversed or penetrated by the point of ...

Flakiness Index and Elongation Index Test on Coarse Aggregates

Shape tests on coarse aggregates such as flakiness index and elongation Index, its importance in concrete construction, methods of determination is discussed. Shape Tests on Coarse Aggregates: Following tests are conducted on coarse aggregates under shape tests: The elongation index of the ...

FIRE PROOF CONCRETE

At the high temperatures experienced in fires, hydrated cement in concrete gradually dehydrates, reverting back to water (actually steam) and cement. This results in a reduction of strength and modulus of elasticity (stiffness) of concrete. In some fires, spalling of ...

Specific Gravity and Water Absorption Tests on Aggregates

Specific gravity test of aggregates is done to measure the strength or quality of the material while water absorption test determines the water holding capacity of the coarse and fine aggregates. The main objective of these test is to, To measure ...
