An extended pressure application for transient seepage problems with a free surface
(Begell House Inc, 2005)
In this paper, a new finite-difference-solution technique for solving transient seepage problems with an unknown free sur ace has been proposed. The governing finite-difference equations were derived using flux conservation ...
Modelling Study on the Geotextile, Geogrid and Steel Strip Reinforced Slopes
(2017)
Zeminin doğal koşullarının değişmesi, yüksek miktarda hafriyat gerektiren otoyol ve demiryolu kenarları veya destekli kazılardaki şev stabilitesi projelerinde beklenmedik gerilme artışlarına neden olmaktadır. Bu işlem ...
A comparative study on the interpretation of concrete core strength results
(Thomas Telford Publishing, 2006)
Cores measuring 94 mm and 144 mm in diameter and having length-to-diameter ratios of 2-0, 1.0 and 0.75 were removed from beam specimens produced from different concrete mixtures. Standard cubes and cylinders were also ...
Use of natural zeolites as a landfill liner
(I W M Business Services LTD, 2003)
The purpose of this study is to investigate certain features of a novel material proposed to serve as an impervious liner in landfills. Various ratios of bentonites and zeolites (B/Z) compacted at optimum water content ...
Statistical distributions of in situ microcore concrete strength
(Elsevier Sci LTD, 2012)
Quality control processes require accurate knowledge of in situ compressive strength of concrete. The most widely accepted method of determining the compressive strength of concrete in existing structures is to test core ...
Use of petroleum-contaminated drilling wastes as sub-base material for road construction
(Munksgaard Int Publ LTD, 2000)
In this study, petroleum-contaminated drilling wastes were stabilized by mixing pozzolanic fly ash, lime and cement with them so they could be used as sub base materials for road construction. This stabilization produced ...
Repeated Creep Behavior of Polypropylene Fiber-Reinforced Bituminous Mixtures
(Asce-Amer Soc Civil Engineers, 2009)
In recent years, research has been devoted to the control of permanent deformations in flexible pavements. In order to prevent rutting, fatigue, and low-temperature cracking, different types of polymer modifiers have been ...
Structural behavior of concrete filled steel tubular sections (CFT/CFSt) under axial compression
(Elsevier Sci LTD, 2014)
In this study, compressive strength, modulus of elasticity and steel tensile coupon tests are performed to determine material properties. Sixteen hollow cold formed steel tubes and 48 concrete filled steel tube specimens ...
Some factors influencing effect of core diameter on measured concrete compressive strength
(Amer Concrete Inst, 2007)
Various concrete mixtures were produced using crushed limestone and river gravels with four different maximum sizes of 10, 15, 22, and 30 mm (0.39, 0.59, 0.87, and 1.18 in.). The 28-day cube strength of concrete mixtures ...
The use of waste materials in asphalt concrete mixtures
(I W M Business Services LTD, 2003)
The purpose of this study was to investigate (a) the effects of rubber and plastic concentrations and rubber particle sizes on properties of asphalt cement, (b) on properties of asphalt concrete specimens and (c) the effects ...
