Toughness characterization of steel fibre reinforced concrete – A review on various international standards
Toughness measurements are considered to be an important scale for evaluating the post crack performance of a fibre reinforced concrete. There are various international standards that lay down different testing procedures and the corresponding deflection measurements. This paper presents a complete review on the various flexural testing methods for fibre reinforced concrete (FRC) prescribed by different...

Pile design using Eurocode 7: A case study
Eurocode 7(EC7) introduces the characteristic and design values with partial factors to reduce uncertainties associated with soil parameters, applying load, etc. The characteristic and design values of soil parameters according to this code were determined, three design approaches of EC7 were evaluated and pile foundation design was assessed suitability using the better one. Moreover the limitation of this...

A Canadian Water Quality Guideline-Water Quality Index (CCME-WQI) based assessment study of water quality in Surma River
Water quality of Surma River is frequently deteriorating for the last few decades since ever-growing human activities, poor drainage facilities, and direct disposal of industrial and municipal waste. Along with poor structure, natural canals (local name Chara) are responsible for the conveyance of surface runoff from its urban catchments to the receiving Surma River. The purpose of this study is to...

Effect of uniform and gradient thermal loadings on cylindrical steel reservoirs (analytical investigation)
Circular steel reservoirs are used extensively for storing petroleum products, water and grains. Additional to uniform thermal loading, gradient thermal loading from sunshine varying angle during day and various seasons is one of important loadings that should be taken into account in design of these reservoirs. In this paper, using finite element modeling of cylindrical steel reservoirs with various...

Effects of limited initial curing durations on mechanical properties of concrete
Mechanical properties (compressive and split tensile strength, sorptivity and coefficient of water absorption) of concrete cube specimens cured in water and ambient air (uncured) for 3, 7, 14, 28 and 90 days were determined. Compressive and split tensile strength properties of concrete specimens that were initially water cured for limited durations of 1, 2, 3, 4, 5, 6, 7, 14, 28 days and subsequently air...
