Mechanical Behavior of Fly Ash Concrete A Critical Review
Abstract: Concrete structure is the most common all over the world. Cement is the major ingredient of concrete. Though the raw materials needed for manufacture of cement are available in most parts of the world, many countries have severe shortage of cement, although their needs are vast. The search for suitable substitute for cement, either partially or fully, has thus become a challenge for planning the development of many of the …

Steepening Pit Walls- Geotechnical and Economic Implications
Abstract: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the …

RUTTING EVALUATION OF BITUMINOUS MIXES USING WHEEL LOAD TESTERS
Abstract: Abstract: Permanent deformation also known as rutting, is the major mode of distress affecting the service life and performance of bituminous pavements. Rutting occurs due to excessive stresses on subgrade, inadequate strength of bituminous mix, inadequate thickness of pavement layers or poor construction methods. Among these causes, quality of bituminous mix is one of the main factors that contribute towards rutting failure.There are several test methods like Uniaxial tests, Triaxial …

Vibration Analysis of Steel Deck due to Moving Load Using ANSYS.
Abstract: Most anthropological goings-on take in vibration in one arrangement or further. For illustration, we receive for our eardrums vibrate and see because light waves undergo vibration. Breathing is associated with the vibration of lungs and walking involves (periodic) oscillatory motion of legs and hands. Human speech requires the oscillatory motion of larynges (and tongues). Early scholars in the field of vibration concentrated their efforts on understanding the natural phenomena and …
