Utilization of Advance Geopolymer in Concrete: A Review
Abstract: Climate change has several adverse impacts like changes in weather, untimely rains, depleting water, droughts, flash floods, acute and early summer and chilling winter. Equally, another bigger challenge to the society is foul smell whether it is river, pond, drain, public toilets or garbage dump yards. It is due to emission of hydrogen sulphide, methane and other toxic gases. Methane in pure form does not create any foul smell, however …

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 …

Manufacturing of interlocking brick with cement- lime mortar and hyposludge
Abstract: Lime is still a valuable building material that is frequently used in construction as lime mortar. Hydrated lime can be added to concrete mixes used to make blocks and other concrete products. Sugarcane mud, also characterized as filter cake, is a byproduct of the sugar purification process. The introduction of these components into the environment pollutes it. There have been several attempts to address these difficulties. A experiment of manufacturing …

Effect of Varying Shear Velocity on the Mechanical Behavior of Jointed Rock Subjected To Lower Normal Load
Abstract: : This study investigates the effect of shearing velocity on the mechanical behavior of rock joints, namely, the shear strength, residual strength, joint dilation, its surface roughness and the shearing stiffness under the application of lower normal load. The slower rate of shearing plays an important role in creep and the fatigue effect on jointed rock masses whereas, higher rate of shearing is experienced in the cases of dynamic loadings …

Predicting the Influence of Permeability’s on Settlement of Shallow Foundation
Abstract: Foundation settlement rose as soil permeability increased, excess pore pressure increased with depth, and decreased as shear modulus increased. The expanding soil cycle (shrinkage and expansion) that is principally responsible for foundation settlement is strongly related to water content. The application of modeling and simulation was used to monitor the effect of various soil properties on foundation settlement. But the focus of this study is on Permeability including other soil …

Finite Element Modeling of RC Beam Column Sub-assemblages Subjected to Column Loss Scenario
Abstract: Progressive collapse is a situation where a failure of whole or large part of a structure occurs that has been initiated by failure of a relatively small part of the structure such as failure of any primary structural element. When a vertical load carrying element, typically a column is lost, the loads that are supposed to pass through lost column need to be safely transferred to the adjacent elements to …

Evaluation of Rutting Susceptibility of Bituminous Mixes Using Finite Element Modeling
Abstract: Pavement performance mainly depends on the quality of bituminous mixes. Poor bituminous mixes cause premature failures such as rutting or permanent deformation, cracking, bleeding etc. The design of bituminous mixes should contain certain criteria to prevent premature failures. The mixes designed based on these criteria are generally known as performance based mix design and are gaining popularity in the recent times. Among various types of pavement failures, permanent deformation or …
