STUDIES ON HIGH STRENGTH SELF COMPACTING CONCRETE WITH COPPER SLAG FOR M30 GRADE

Applying Solid Residues of Copper Slag in Kerman Sarcheshme of Iran as Sand Replacement for Self-Compacting Concrete

The reuse of mineral wastes is one of the most suitable solid wastes solutions. Throughout the world, the large of the granular aggregates used in constructions exploit natural mountain resources and rivers. Using mineral waste as a part of concrete, it can be helped to create a green environment and also contribute to sustainable development. Since the copper production process in the Sarchesh...

Effect of W/C Ratio on Workability and Mechanical Properties of High Strength Self Compacting Concrete (M70 Grade)

This paper presents the results of an experimental research on the workability and mechanical properties of self-compacting concrete. The work focused on concrete mixes having Water/Cement ratios of 0.23, 0.24, 0.25, 0.26 and 0.27, with a Packing Factor of 1.12. The Concrete mixes contains different proportions of GGBS, Super plasticizers, water binder ratios and constant proportions of Cement,...

Ultra High Performance Self Compacting Concrete

Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...

Self-compacting Concrete (scc)

Relation between the Workability and Strength of Self-compacting Concrete

This paper presents the results of an experimental research on the workability and compressive strength of self-compacting concrete. The work focused on concrete mixes having water/binder ratios of 0.35 and 0.45, which contained constant total binder contents of 500 kg/m and 400 kg/m, respectively. The concrete mixes contained four different dosages of a superplasticizer based on carboxylic wit...
