Is code for self compacting concrete mix design?

This paper deals with the Mix design of Self-Compacting concrete. The highlight of this paper is, simplest process of Mix design according to Indian Standard Code of Mix design (IS-10262) and It follows all the design conditions in line with Indian Standard Code of Reinforced Concrete Structure (IS:456).

What are the material used for self compacting concrete?

Self-Compacting Concrete Materials Portland Cement: Common Portland cement grade 43 or 53 is commonly used. Aggregates: The size of coarse aggregate is limited to 20 mm, but in case of having a structure with congested reinforcement, the aggregate size can range between 10 to 12 mm.

What is Nan Su method?

Nan-Su et al proposed a simple mix design method for self-compacting concrete the amount of aggregates required is determined, and the paste of binders is then filled into the voids of aggregates to ensure that the concrete thus obtained has flow ability, self-compaction ability and other desired SCC properties.

What are the requirements for self compacting concrete?

Self-compacting concrete (SCC) is design to achieve three functional requirements, which are filling ability, passing ability, and resistance to segregation.

Are there any concrete mix design procedures for self compacting?

One of the limitations of SCC is that there is no established mix design procedure yet. This paper describes a procedure specifically developed to achieve self-compacting concrete. In addition, the test results for acceptance characteristics for self-compacting concrete such as slump flow, J-ring, V-funnel and L-Box are presented.

How is the compactibility of SCC mix affected?

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 presents an experimental procedure for the design of self-compacting concrete mixes.

What should free surface moisture be for self compacting concrete?

Free surface moisture of ratio of 0.33–0.40; the optimization is started with an Coarse aggregate : NIL assumed value of w/c and this is reduced if the desired Fine aggregate : NIL strength is not attained. Next, using the mini-slump test, 3.

How is a read counted in self compacting concrete?

A ‘read’ is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration.
