Optimization of lightweight GGBFS and FA geopolymer mortars by response surface method
(ELSEVIER SCI LTD, 2017-05-15)
In the first stage of the paper, the effect of binder content, curing temperature and curing time on the compressive strength of light-weight geopolymer mortar (LWGM) was investigated. The base materials used for LWGM are ...
Effect of aggregate properties on the mechanical and absorption characteristics of geopolymer mortar
(ELSEVIER - DIVISION REED ELSEVIER INDIA PVT LTD, 2017-12)
Even though aggregate constitutes major volume in geopolymer concrete, only limited study related to this parameter has been reported. This paper presents the summary of study carried out to understand the influence of ...
Experimental and analytical study of the mechanical and flexural behavior of hybrid fiber concretes
(Elsevier Ltd, December 2)
The use of fibers in Reinforced Concrete (RC) structures may improve the properties of concrete; like reducing the shrinkage strain and increasing the tensile, flexural, and bond strength. This article presents an experimental ...
A simple formula for estimating the column ultimate load with effect of semi-rigid connections
(KOREAN SOC STEEL CONSTRUCTION-KSSC, 2015-03)
Calculating the ultimate load of a framed column in sway structures involves, in the currently used design method, the calculation of the column effective length and utilizing the interaction formulae or tables. Therefore ...
Nonlinear Finite Element Model for the Optimization of Post-Tensioned One-Way Concrete Slab
(KOREAN SOCIETY OF CIVIL ENGINEERS-KSCE, 2018-07)
Optimization in its wide sense can be used to solve many engineering problems and to find the best solutions so that designers can gain a maximum benefit from the available resources. In this research a nonlinear Finite ...
Behaviour of steel cap plate connections: Experimental tests
(KOREAN SOC STEEL CONSTRUCTION-KSSC, 2014-09)
This paper reports the results of a study conducted to investigate the behaviour of steel cap plate connections. In the analysis and design, connections are characterized as either rigid or pinned and between these two ...
Multi-Objective Optimization of Alkali Activator Agents for FA- and GGBFS-Based Geopolymer Lightweight Mortars
(SPRINGER HEIDELBERG, 2018-10)
This article presents the effect of different sodium hydroxide (NaOH) concentrations and sodium silicate-to-sodium hydroxide (Na2SiO3/NaOH) ratio on the fresh and some hardened properties of lightweight geopolymer mortar ...
Fresh Properties of Cementitious Grout with Rice Husk Powder
(SPRINGER HEIDELBERG, 2017-09)
This paper reports the results of a study conducted to investigate the effects of rice husk powder (RHP) on the rheological properties and the fluidity of grout mixtures. The experiments were carried out with the grout ...
Fresh, Mechanical and Absorption Characteristics of Self-Consolidating Concretes Including Low Volume Waste PET Granules
(C EJ PUBLISHING GROUP, 2017-10)
This study evaluates the effect of waste polyethylene terephthalate (PET) granules on the fresh, mechanical and absorption characteristics of self-consolidating concretes (SCCs). Fine aggregates were replaced with different ...
Finite element analysis and optimization of bonded post-tensioned concrete slabs
(TAYLOR & FRANCIS AS, 2017-06-22)
Optimization techniques may be effective in finding alternative design of post-tensioned slabs to improve their mechanical behaviour, particularly reducing the bending moments. Post-Tensioned (PT) concrete one-way slabs ...
