Application of Light-burnt Dolomite as a Mineral Addition in Concrete
Author(s) Zhiyang Chen Min Deng Peng Liu Abstract Growth in the production of cement has led to increasing demands for mineral additions. This study was conducted to develop an alternative addition by calcining dolomite at 800°C to obtain a mixture of periclase...
Effect of Grinding on the Quantification of Bound Water in Tricalcium Silicate
Author(s) Shiju Joseph Özlem Cizer Abstract The effect of grinding hydrated tricalcium silicate (C3S) pastes on the bound water content (BWC) measured by thermogravimetric analysis was investigated. The samples were subjected to different curing regimes at 20°C...
Effects of Packing Density and Water Film Thickness on Fresh and Hardened Properties of Ternary Cement Pastes
Author(s) Guillermina Marchetti, PhD Edgardo Fabián Irassar, MEng Viviana Fátima Rahhal, Dr MEng Abstract Optimisation of the packing density of cementitious materials by the addition of supplementary cementitious materials (SCMs) is a way of obtaining the same...
Behaviour changes of ground granulated blast furnace slag geopolymers at high temperature Author(s)
Author(s) Ikmal Hakem Aziz Mohd Mustafa Al Bakri Abdullah Cheng-Yong Heah Yun-Ming Liew Abstract In this paper, the thermal performance of ground-granulated blast furnace slag (GGBFS) geopolymers is investigated. The geopolymers were prepared with sodium-based...
Modeling Early-Age Rheology of Cement-Silica Fume Pastes
Author(s) Jedadiah F. Burroughs, Charles A. Weiss Jr., John E. Haddock, and W. Jason Weiss Abstract This study presents the application of an analytical model to describe the rheological behavior of cement pastes containing silica fume at replacement rates of...
No AccessAnalysing the Effect of Principal Stress Rotation on Railway Tack Settlement by Discrete Element Method
Author(s) Xuecheng Bian* Wei Li* Yu Qian† Erol Tutumluer‡ Abstract Principal stress rotation induced by moving loads from trains significantly influences railway track settlement accumulation. The stationary cyclic loading commonly adopted to study railway...
Behaviour of Discrete Piles used to Stabilise a Free-covered Railway Embankment
Author(s) Joel A. Smethurst* Nicola Bicocchi† William Powrie* Anthony S. O'Brien‡ Abstract Many clay railway embankments in the UK are well over 100 years old, and now suffer from a range of stability and serviceability problems. A common means of remediating...
Mathematical Modelling of the Mechanical Response of Earth Embankments on Piled Foundations
Author(s) Claudio di Prisco* Luca Flessati† Gabriele Frigerio* Andrea Galli* Abstract Piled foundations are largely employed as settlement reducers in the design of artificial embankments on soft soil strata. The commonly employed design methods are, however,...
Glass-fibre-reinforced polymer: The Low Carbon Dioxide Option for Permanent Rock Bolts
Author(s) Alun H. Thomas, BA, PhD, CEng, MICE Abstract Traditionally steel has been used for rock bolts in tunnelling. Faced with the challenge of reducing mankind's environmental impact, it is necessary to look at using better alternatives....
