Construction material subjected to repetitive or cyclic loading have to be qualified for their fatigue behaviour. Generally their behaviour is considered satisfactory if they withstand two million cycle of repetitive loading without distress or failure at that required mean stress level and range stress.
The recent research in reinforcing Portland cement based material with randomly distributed fibres was spurred by pioneering research or fibre reinforced concrete (FRC) conducted in the United state in the 1960s.The addition of fibre in the co ....etc

Superplasticisers are high range water reducing admixtures..Admixture is defined as a material other than cement ,water and aggregate that is used as an ingredient of concrete and is added to the batch immediately before or during mixing. The development of superplasticisers is one the major break throughs in concrete technology, which will have a significant effect on the production and use of concrete in the next millennium. Superplasticisers have been greatly responsible for development of the following connects.
1) High performance connect ....etc

Self Compacting Concrete (SCC) is defined as a category of High Performance Concrete that has excellent deformability in the fresh state and high resistance to segregation, and can be placed and compacted under its self weight without applying vibration. SCC was first developed in Japan in mid 1980. Since then, it has found applications in reinforced concrete sections containing congested reinforcements. Poor quality of vibration of concrete, in congested locations, has often been a shortcoming of traditional concrete. In such situations, SCC, ....etc

Different types of Non-Destructive tests (NDT) are there to detect voids and cracks in concrete such as Ultrasonic Pulse Echo, Ultrasonic Pulse Velocity, Ground Penetrating Radar, Impact Echo Method, X-ray Scanning Method, Rebound Hammer Method, Infrared Thermography Method .In which Infrared Thermography method is discussed in this paper
As concrete is used in newer areas and evidence is coming to light of premature deterioration in concrete structures there is a need to develop new methods for quality control at the time of concrete construc ....etc

INTRODUCTION :-

Openings are invariably left in the wall for the provision of doors, windows, cupboards, almirahs, wardrobes, etc. And these openings are bridged by the provision of a lintel.

It is often desirable for structural steel members to pass through a fire wall
or common wall rather than being curtailed on each side of the wall. In such cases, the penetrating member will often be fire protected for a certain length on each side of the wall so as to minimise the possibility of fire spread through heat conduction and excessive temperature rise of the member on the unexposed side of the wall. This latter aspect is necessary to ensure that lateral restraint will continue to be provided to the top of the wall by the member on t ....etc
