In this study, the benefits of limestone powder (LP) and marble powder (MP) as partial replacement of Portland cement are established. Furthermore, LP and MP are used directly without attempting any additional processing in the production of selfcompacting concrete (SCC). The water to binder ratio is maintained at 0.33 for all mixtures. The examined properties include workability, compressive s...

Increasing trend in urbanization and industrialization has necessitated production of high rise buildings with an innovation to make an optimized use of reduced available land in thickly populated areas, which is not possible by standard conventional concrete. Such a different concrete can be created only through different types of admixtures, which when added at various stages of concrete prod...

The vibrations produced by earthquakes cause large horizontal forces in beam-column joints. If these exceed the limit values that joints can withstand, severe irreparable damage might occur. Experimental and analytical studies were conducted to determine energy dissipation capacity ductility of using “Self-compacting Concrete” (SCC) “Normal (NC) mixes containing various quantities steel fibres....

This study presents an experimental investigation on self-compacting concrete (SCC) with fine aggregate (sand) replacement of a Quarry Dust (QD) (0%, 25%, 50%, 75%, 100%) and addition of mineral admixtures like Fly Ash (FA) and Silica Fume (SF) & chemical admixtures like super plasticizers (SP). After each mix preparation, 45 cubes specimens and 45 cylinders specimens are cast and cured. The sp...

In order to model the effect of mixture parameters and material properties on the hardened properties of, prestressed self-compacting concrete (SCC), and also to investigate the extensions of the statistical models, a factorial design was employed to identify the relative significance of these primary parameters and their interactions in terms of the mechanical and visco-elastic properties of S...

A Lagrangian particle-based method, the smooth particle hydrodynamics, is used to model the flow of ultra-highperformance, self-compacting concretes containing short steel fibres which behave like a non-Newtonian fluid described by a Bingham-type constitutive model. An incompressible smooth particle hydrodynamics method is used to simulate the flow after the kink in the shear stress against the...

this study investigates the prediction model of compressive strength of self–compacting concrete (scc) by utilizing soft computing techniques. the techniques consist of adaptive neuro–based fuzzy inference system (anfis), artificial neural network (ann) and the hybrid of particle swarm optimization with passive congregation (psopc) and anfis called psopc–anfis. their performances are comparativ...
