How to Build a Cinder Block Wall?
Cinder blocks or concrete masonry units are building blocks made from concrete and other coal cinders. A cinder block unit is very light when compared to other building blocks because of a lesser proportion of aggregates and other ingredients possessed ...
How to Choose Water Pumps for Construction Sites?
Water pumps are commonly used on construction sites to remove excess water accumulated due to heavy rain or high water table. They primarily serve two purposes: keep water out of foundations, tunnels, and other excavations pits; and provide a supply ...
Void Forms in Foundation Construction: Their Types and Applications
Void forms are sacrificial formwork members designed to provide a space between the concrete foundation and expansive soil, i.e., to protect the foundation from the heave of the underlying soil. They also offer a temporary support formwork for recently poured ...
How to Inspect a Structure Using Acoustic Emission Testing?
Acoustic emission (AE) is defined as the physical phenomenon in which a material generates elastic waves when subjected to stress or deformation. These signals are registered using a non-destructive test method (NDT) called the acoustic emission test. An acoustic emission ...
How to Retrofit Inclined Columns Damaged Due to Earthquakes?
The required load-carrying capacity of columns damaged due to earthquake can be regained by retrofitting the inclined columns. During earthquakes, the top and bottom parts of a column are most vulnerable to shear forces. If the forces are large, the ...
How to Properly Splice Column Reinforcement as per Indian Standards?
Lap length or overlapping length is the length at which two bars of a column are spliced or overlapped in order to maintain the continuity of the bars throughout the length of the column. This method of overlapping two reinforcement ...
How Climbing Formwork Makes Concrete Construction Easy?
Climbing formwork is a special type of formwork that rises along with the progress of vertical concrete construction. It can move on its own by using an electric or hydraulic jack. Such formworks are also called self-climbing formworks. It is ...
