2016-12-15  One way of achieving this objective is to incorporate mineral admixtures like Fly Ash (FA), Metakaolin (MK), Silica Fume (SF), Nano Silica (NS), Ground Granulated Blast Furnace Slag (GGBS) etc. in the concrete. These mineral admixtures can play the role of micro-fillers which in turn will increase the compactness and decreases the porosity of concrete , . By extending this hypothesis to SCC made with RCA, it is reckoned that by adding suitable mineral

Self-compacting concrete (SCC) is design to achieve three functional requirements, which are filling ability, passing ability, and resistance to segregation. These requirements are necessary to properly fill the formwork and adequately encapsulate reinforcing bars only through the action of gravity, while maintaining good homogeneity.

2019-6-17  Self-compacting concrete produces resistance to segregation by using mineral fillers or fines and using special admixtures. Self-consolidating concrete is required to flow and fill special forms under its own weight, it shall be flowable enough to pass through highly reinforced areas, and must be able to avoid aggregate segregation.

Self-Compacting Concrete (SCC) is defined as concrete that has an ability to flow under its own weight, to fill the required space or formwork completely and to produce a dense and adequately homogenous material without a need for vibrating compaction, [1]. Rheological properties are the dominant feature of SCC with regard to its designing and processing.

1995-10-1  More recently, two lines of research have been followed. The first concerns compact granular matrix concretes (DSP), with high superplasticizer and silica fume content, also incorporating ultra-hard aggregate (calcinated bauxite or granite) (3). The other line of research relates to MDF (Macro Defect Free) polymer pastes (4).

2012-4-1  Before the test, it was assumed that the incorporation of LP could improve the fluidity of the fresh concrete, but might be detrimental to the mechanical behavior of the hardened concrete with such a low W/B. Surprisingly, compared with mixture 4-1 with 0% LP as a control, mixture 4-2 with 20% LP replacement achieved a higher slump of 240 mm, and a greater compressive strength at ages from 28

2019-6-17  Self-Compacting Concrete Uses . Self-compacting concrete has been used in bridges and even on pre-cast sections. One of the most remarkable projects built using self-compacting concrete is the Akashi-Kaikyo Suspension Bridge.In this project, the SCC was mixed on-site and pumped through a piping system to the specified point, located 200 meters away.

The quality of water used is same that followed for reinforced concrete and prestressed concrete construction. 4. Mineral Admixtures The mineral admixtures used can vary based on the mix design and properties required. Mentioned below are the different mineral admixtures that can be used and their respective properties they provide.
