Equivalent CO2 Emission and Cost Analysis of Green Self-Compacting Rubberized Concrete

چکیده
Global warming and climate changes are the major environmental challenges globally. With CO2 emission being one of main greenhouse gases emitted to environment, cement concrete production amounting about 10% global emission, there is a need for construction industry utilize an environmentally sustainable material as alternative cement. This study analyzed cost, strength properties green self-compacting (SCC) ternary blend containing fly ash, calcium carbide residue (CCR), crumb rubber (CR) replacement by volume cement, cementitious material, fine aggregate, respectively. Cement was replaced with ash at 0% 40% volume. CCR used 5% materials, CR aggregate in proportions 20% The result indicated that mix most expensive had highest emission. However, CR, lowest therefore greenest SCC mix. 28-day maximum compressive 45 MPa achieved CCR, while utmost splitting tensile 4.1 flexural 28 days 6.7 also obtained CCR. In conclusion, can be produced substituting which highly affordable has acceptable recommended conventional SCC.

Properties of Self-compacting Concrete – an Overview
Self-compacting concrete can be defined as the concrete which requires no vibrations and can flow around obstructions, encloses the reinforcement and fills up the formwork completely under its self weight. Over the last ten years, significant amount of work has been carried out on self-compacting concrete all over the world. In countries like Japan, Sweden, Thailand, UK etc., the knowledge of S...
متن کاملUltra 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...
متن کاملSelf-Compacting Concrete - Procedure for Mix Design
Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper...
