Hot Weather Concreting – Effect of Hot Weather on Concrete
Hot weather has a significant effect on all stages of concrete production and placement procedures such as increasing rate of hydration and movement of moisture from within ...
Corrugation and Shoving in Flexible Pavements – Causes and Remedies
Corrugation and shoving are two defects that usually occur in flexible pavements. Weak sub-grade conditions, improper rolling, poor mixing, temperature effect of bitumen, and weak bottom layers are different causes of corrugation and shoving in flexible pavements.
Factors Affecting Selection of Hydraulic Turbine
The hydraulic turbines or water turbines are important hydraulic machines of the hydropower plant that convert the hydraulic energy into mechanical energy. There are different types of turbines such as a Pelton turbine, Kaplan turbine, Francis turbine, bulb ...
Top 10 Estimation Software in Construction Industry
The most basic requirement for the preparation of a good bid is a precise and accurate estimate. If prepared by hand, not only the process would be laborious but also liable to errors. With the rapid digitalization of ...
Concrete Delamination- Causes, Effects, and Precautions
Concrete delamination is the detachment of thin layers of concrete from the concrete surface. The peeled-out concrete surface then becomes prone to all kind of abraders in the atmosphere which consequently weaken the structure. It, therefore, becomes extremely ...
Hydraulic Coefficients of an Orifice
The laboratory experiment procedure to determine hydraulic coefficients of an orifice is explained in this article. The coefficient of contraction, the coefficient of velocity and coefficient of discharge are hydraulic coefficients of an orifice.Theory
Reynolds Experiment
The procedure for conducting laboratory experiment to find critical Reynolds number for a pipe flow in different discharge conditions is explained in this article.Reynolds number is the ratio of the inertial force of flowing ...
How to Repair Active Cracks in Concrete?
Active cracks in concrete are live cracks which expand in length, width, and depth over time. These cracks are formed due to overloading and thermal expansion e.g. cracks due to freeze-thaw. Common methods to repair active cracks are drilling and ...
