An Investigation on Aggregate Distribution in Concrete
Abstract: Falling behavior is generally studied by mathematicians. The first study is conducted by Comte de Buffon with name “Falling needles experiment” and is widely known. Buffon researched the falling needle behavior finding the fall of needles in relation with Pi. However, although aggregates are fallen to the mould in cement paste, falling behaviour of concrete is rarely studied considering the statistical parameters of the fall.Accordingly, an experimental study is conducted …

Application of Fly Ash and Lime as Partial Replacement of Cement in Concrete
Abstract: Concrete as a construction material plays a significant role in infrastructures development in the world. The main constituents of concrete are cement, fine aggregate, coarse aggregate, and water. Production of cement has been emitting a huge amount of carbon dioxide in the atmosphere. Hence causing environmental pollution. Amount of fly ash generation has been increasing day by day which has also been damaging the environment in the form air, water …

A Review on Waste Bakelite as Replacement Partially Over Coarse Aggregate in Concrete Mix
Abstract: Various components in India are made up of Bakelite. Saffron Global Dumping of waste Bakelite through landfill is not allowed due to it effect on soil mass and open burning is not allow because of the emission of harmful gases which cause air pollution. A large space of storehouse requires to store large amount of area for keeping waste Bakelite which becomes management problem of waste. Despite managing waste Bakelite …

The Environmental Impact of Soil Pollution on Human Health
Abstract: Soils are shaped by the decomposition of rock and organic matter over several years. Soil properties vary from place to place with difference in bedrock composition, climate and other factors. Certain chemical elements occur naturally in soils as components of minerals, yet may be toxic at some concentration. Various other potentially harmful substance may end up mixing with soils through human activities. This may lead to soil contamination which in …

Dynamic Response of Bridges and its Effect on Soil Medium
Abstract: The analysis of dynamic behaviour of bridge structures that are subjected to moving loads has been one of the research benefits in recent years. Specifically in railway bridges, resonance ensues when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been practical in railway bridges, especially subjected to high-speed lines. They are caused primarily because of two reasons: one is the repeated …
