Engineering properties of self consolidating concrete

The key to creating self-consolidating concrete (SCC), also referred to as self-compacting, self-leveling, or self-placing concrete, is a mixture that is fluid, but also, stable, to prevent segregation.

Aggregates are classified by ASTM C33 (AASHTO M 6/M 80) as fine or coarse.

Fine aggregate consists of natural sand, manufactured sand, or a combination thereof with particles that are typically smaller than 0.2 inches.

Using concrete for building structures and infrastructure can contribute to the emission of carbon dioxide.

Almost all construction processes from manufacturing, through transportation of materials and installation use energy, and much of this energy may come from the burning of fossil fuels.

It will contribute to environmental protection and the resource recycling initiative.

Since the mix design of self-consolidating concrete (SCC) differs from that of conventional concrete, mechanical properties of SCC may differ from those of vibrated concrete.The results indicated that 100% stainless steel oxidizing slag (SSOS) substitutes to aggregates and 30% stainless steel reducing slag (SSRS) substitutes to Portland cement in SCC, the values of compressive strength, electrical resistivity and the 91 day ultrasonic pulse velocity are within the good quality concrete requirement.It could save 43% cost of SCC with this substitution.Two high-performance concrete mixtures that represent typically concrete used for precast, prestressed applications were investigated for the control mixtures.They were proportioned with 0.34 and 0.38 w/cm and had slump values of 150 mm.This paper presents the results of an investigation on engineering properties of self-compacting concrete (SCC) containing oxidizing and reducing slag generated from stainless steel making.
