“…SCC can only be cost effective if more economical mixture ingredients are introduced on the market (Uysal and Yilmaz 2011). Incorporation of inert, pozzolanic/hydraulic additions or waste and recycling materials as substitutions for high amounts of cement may significantly improve the material cost effectiveness of SCC.…”

In this study, the fresh properties of self-compacting concrete (SCC) incorporating ground waste glass (GWG) as cementing material were experimentally investigated. GWG was used as a partial replacement for cement at replacement levels of 0, 5, 10, 15, 20, 25 and 30% by weight. Reducing the consumption of cement in construction is a major issue in terms of economic performance. Such reduction would also contribute to the environment by lessening the harmful impact of the manufacturing process. Concrete mixtures containing different levels of GWG were prepared with the water to cementitious materials ratio of 0.51. The examined properties included workability, wet density, air content and setting time. Workability of the fresh concrete was determined by using the slump flow, visual stability index, V-funnel, J-ring, L-box and GTM screen stability tests. The results indicate that there is a slight decrease in the wet density of self-compacting ground waste glass concrete (SCGWGC) of nearly 1.37% with the increase of GWG content. The conclusion is that using GWG significantly increases the workability of SCC mixtures. As the GWG increases, the slump flow also increases at a constant amount of water and super-plasticizer, but the concrete flow time decreases. The results showed that it is possible to successfully produce SCC with GWG as cement replacement.

“…However, these results should be supported later by rheological tests. Uysal and Yilmaz (22) reported that mixtures containing mineral admixtures generally showed better performance than the control mixtures in regards to workability due to better particle distribution and reduction in interparticle friction leading to increased packing density and decreased flow resistance.…”

ABSTRACT:This study evaluates the use of large amounts of fine powders (fillers) derived from a Colombian volcanic material into the production of self-compacting concrete (SCC) for lower strength applications. The effects on SCC properties were studied with the incorporation of up to 50% of volcanic material of Tolima (MVT) as a partial substitute of the total weight of Portland cement. The workability was determined through slump flow, V-funnel, and L-box test. The compressive strength results were analyzed statistically by MINITAB. These demonstrated that 30% (by total weight of cementitious material) was the maximum allowable percentage of MVT to be used in the production of SCCs. Based on this, mechanical and permeability properties of SCC MVT 30% were evaluated at 28, 90 y 360 curing days. SCC MVT 30% exhibited compressive strength of 21 and 27 MPa after 28 and 360 days of curing, respectively. RESUMEN: Uso de un material volcánico como filler en la producción de hormigones autocompactantes de baja resistencia.Este trabajo presenta los resultados de utilización de cantidades elevadas de material volcánico colombiano como filler en la producción de hormigón autocompactante (CAC) de baja resistencia. Se estudió el efecto sobre las propiedades de los CACs de la incorporación del material volcánico del Tolima (MVT) hasta en 50% como remplazo parcial del peso total del cementante. La trabajabilidad fue determinada por medio del flujo de asentamiento, embudo V y Caja L. El análisis de resistencia a la compresión por medio de MINITAB demostró que el máximo porcentaje de incorporación de MVT en los CACs es del 30% respecto al peso total de cementante. Con base en esta optimización se evaluaron sus propiedades mecánicas y de permeabilidad a 28, 90 y 360 días de curado. Los resultados demostraron que este CAC MVT 30% presentó resistencias a compresión de 21 y 27 MPa después de 28 y 360 días de curado, respectivamente.

“…The correlation between strength and UPV is also poor. Uysal & Yilmaz, 2011 reported the UPV values ranged from 4222 m/s to 4998 m/s for strength value of 55 to 105 MPa for concrete containing limestone powder (LP), basalt powder (BP) and marble powder (MP). They also found that the use of limestone powder ( L P ) , b a s a l t p o w d e r ( B P ) a n d m a r b l e p ow d e r ( M P ) a s c e m e n t r e p l ac e m e n t a t v a ri o u s contents had caused a reduction in UPV as well as the compressive strength compared to the control mixture.…”
