How to Test Reinforced Concrete Structures for Watertightness?
A watertightness test is conducted on water-containment structures to check whether undetected and incidental defects are leading to leakage of water. The types of linings used in a water-containment structure, their location (semiarid or arid area, covered or not), and ...
How to Design a Longitudinally Spanning R.C.C Staircase?
A staircase is an important component of a building that is planned and designed based on the type and orientation of the building. Therefore, it is impossible to recommend a definite dimension for the stair without a clear idea about ...
How to Measure the Rate of Water Absorption by Hydraulic Cement Concrete?
The water absorption test determines the water absorption rate (sorptivity) of both the outer and inner concrete surfaces. The test involves the measurement of the increase of mass of concrete samples resulting from the absorption of water as a function of ...
How to Design Plain Concrete Footing for R.C.C Columns as per Indian Standards?
Plain concrete footing or pedestal is a shallow foundation designed to take small loads from columns without using longitudinal tension steel. These are the most economical forms of shallow foundation. To sustain temperature and shrinkage stresses, the standard codes recommend ...
Effective Communication on Construction Sites Means Better Productivity
The construction industry makes a profit or loss based on the visibility of the works performed on the job site. In this sense, one should have the ability to get a clear and complete view of the progress of the ...
Design of Doubly Reinforced Concrete Rectangular Beams with Example
The doubly reinforced concrete beam design may be required when a beam’s cross-section is limited because of architectural or other considerations. As a result, the concrete cannot develop the compression force required to resist the given bending moment. In that ...
Non-Conformance Report (NCR): How To Report Construction Quality Issue?
The quality issues observed in construction practices are addressed in a report called the non-conformance report or the non-conformity report (NCR). An NCR explains the deviation of a specific construction work or task from the required standards and specifications. An ...
