Penetration resistance test is conducted on concrete structures using Windsor Probe test machine. In this test method, a steel probe is fired on the concrete surface by a sudden explosion. The penetration is inversely proportional to the strength of concrete. The ...
Be it the season with extreme heat, extreme cold or inclement rains, Civil Engineers should be accustomed to fight all kinds of seasonal fluctuations. These fluctuations bring in different impediments in front of the constructor which are necessary ...
Quicksand condition is the floatation of particles of cohesionless soil, like fine gravel and sand, due to vertical upward seepage flow. As sand boiling occurs, the bearing capacity and shear strength of the cohesionless soil decrease and the ...
The total weight of steel bars can be determined by calculating the unit weight of each bar. This is calculated after the final estimation of total steel required for a construction project.In this ...
Sand or fine aggregate is one of the most important construction materials at any construction site. Its selection should be done very carefully as it contributes to the strength of various important mixtures like concrete, plasters and mortar. ...
There are various types of materials which are used for the repair of concrete structures. For instance, unmodified Portland cement mortar or grout, latex modified Portland cement mortar or concrete, quick setting non-shrink mortar, and polymer concrete. The ...
The stress-strain curve describes the behavior of steel bars under loads. It is created by testing steel specimens. A steel specimen is gradually pulled through a testing machine until it breaks, and stress and corresponding strains are recorded. ...
A Universal testing machine (UTM) is used to test the mechanical properties (tension, compression etc.) of a given test specimen by exerting tensile, compressive or transverse stresses. The machine has been named so because of the wide range ...
