Day to day a large development in construction activities are happening. All constructions require huge quantity of concrete. we know that conventional concrete has density 2400 kg/m3.This type is not at all required aspects. So new era concretes developed solve more problems. In general Components buildings have kg/m3. high rise the components size. Thus, by making lighter, needs lesser while ...

Timber-concrete composite (TCC) slabs play an essential role in modern timber construction. Consisting of a member the tension zone, concrete layer compression zone and shear connection between two parts, TCC feature number advantages that make them ideally suitable for use both office residential buildings. However, currently used slab systems carry loads only one direction. In frame large res...

In this paper, the effect of Polypropylene Fibers added to concrete on strength and thermal resistance of high strength concrete has been investigated. Therefore, five tests have been carried out to reach this goal which it includes; effect of weight percent of polypropylene fibers on mechanical properties of concrete, effect of fiber’s length on the strength of high strength concrete, effect o...

The controversy over the use of nuclear energy fundamentally comes down to three main considerations: its safety of use, ability of nuclear energy generation to reduce greenhouse gas emissions and finally its long term sustainability. The paper addressed the problem of safety in the industrial and medical use of nuclear energy, as it is affected by the design and construction of light and heavy...
