TYPES OF CRACKS IN REINFORCED CONCRETE SLABS 1. Cracks in reinforced concrete columns due to Steel Corrosion (cracks parallel to steel bars) 2. Cracks in reinforced concrete columns due to shrinkage of concrete 3. Cracks in reinforced concrete columns due to increased load on the slab 4. Cracks in reinforced concrete columns due to sulphate(…)
DISTRESSES IN CONCRETE PAVEMENT
CONCRETE PAVEMENT DISTRESSES a) Cracking Cracks in concrete pavements often result from stresses caused by expansion and contraction or warping of the pavement. Overloading, loss of subgrade support, and insufficient and/or improperly cut joints acting singly or in combination are also possible causes. Several different types of cracking can occur: (i) Longitudinal, Transverse, and Diagonal(…)
GREEN ROOFING – A STEP TOWARDS SUSTAINABILITY
A green roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. (The use of “green” refers to the growing trend of environmentalism and does(…)
FIBRE REINFORCED CONCRETE IN PAVEMENTS
Fibre reinforced concrete (FRC) is defined as a composite material consisting of concrete reinforced with discrete randomly but uniformly dispersed short length fibres. The fibres can be made of steel, polymer or natural materials. Woven fabrics, long wires, bars, and continuous wire mesh are not considered discrete fibres. FRC is considered as a material of(…)

PUMPED CONCRETE PUMP TYPES & SELECTION
Pumped concrete is the concrete which is transported to heights by means of pumping using concrete pumps. This method is used where large quantity of concrete work is involved at greater height, where other means of transporting is not easy to do. Concrete pumps have been known for more than 50 years. In modern times,(…)
PROJECT MANAGER & PROJECT MANAGEMENT
A project is a temporary endeavor undertaken to achieve a particular aim. At the most basic level, a project is actually the response to a need, the solution to a problem. Further it is a solution that promises a benefit especially financial benefit. The fundamental purpose for most projects is to either make money or(…)
