Self Compacting Concrete | PDF | Construction Aggregate
This document discusses sustainable self-compacting concrete where fine aggregate is replaced with Granulated Blast Furnace Slag (GBFS). The objectives are to examine if the concrete mixes meet self-compacting criteria, reduce fine aggregate usage by replacing it with GBFS, and increase strength. A mix design for M40 grade concrete is developed …
Self Compacting Concrete (SCC) | PDF | Concrete
This document discusses self-compacting concrete (SCC), including its history, properties, constituent materials, testing methods, and advantages over traditional concrete. SCC was developed in Japan in the late 1980s as a solution to problems with traditional concrete like poor workability and durability. SCC is able to flow and fill …
Glass powder replacement in self-compacting concrete …
The effect of replacement of Portland cement using glass powder on fresh and mechanical properties of self-compacting concrete (SCC) was investigated in this study. A standard SCC mix design was used with substitution with either fly ash or glass powder of different fineness and replacement levels. Compressive strength, splitting …

New Methodology for Designing Self-Compacting Concrete
Keywords: cement paste; concrete; slump. DOI: 10.14359/10841. Date: 11/1/2001. Abstract: A new segregation-controlled design methodology is introduced for self-compacting concrete (SCC). The theory suggests that aggregate segregation is governed by the yield stress, viscosity, and density of the cement paste matrix.
Steel Fiber Reinforced Self-Compacting Concrete: A …
Self-compacting concrete (SCC), which flows under its own weight without being compacted or vibrating, requires no outside mechanical force to move. But like normal concrete, SCC has a brittle character (weak in tension) that causes sudden collapse with no advance notification. The tensile capacity of SCC has increased owing to the addition …
