Also, it is observed that the addition of polypropylene fibres has reduced the fresh properties of self compacted concrete. However, M-sand with 0.15% polypropylene fibres has slightly improved the strength of self compacting concrete, compression strength by 6.97%, split tensile by 8.68% and flexure strength by 3%.5. INTRODUCTION Concrete that requires little vibration or compaction has been used in Europe since the early 1970s but self- compacting concrete was not developed until the late 1980's in Japan.

Materials Used for Self Compacting Concrete. The main ingredients used in design of self compacting concrete are: 1. Cement. Ordinary Portland cement either 43 or 53 grade cement can be used. 2. Aggregates. The size of the aggregates used for SCC design is limited to 20mm.The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. Self compacting concrete (SCC) was first developed in 1988 in Japan to achieve durable concrete structures. As SCC has various advantages over normal concrete, it also having leakage problems and shrinkage problems.(PPT) Scc presentation.....1 [Autosaved] prakash pradhan

Self-compacting concrete can be made with ordinary/regular Portland cement in grades 43 or 53. 2. Aggregates. The aggregate size utilized in SCC design is limited to 20mm. If the structure’s reinforcement is crowded, the aggregate size can be 10 to 12mm. The optimum choice is well-graded aggregates in round or cubical shapes.A robust mix design method for self-compacting concrete. A theoretical framework for analyzing SCC’s fresh behavior was established. Multilevel excess layer model and rheology-based workability criteria were merged.

SELF COMPACTING CONCRETE (SCC) • Self-Compacting concrete (SSC) is a very special type of concrete which can flow and fill into every corner of formwork, even in the presence of Abstract. Self-compacting concrete is the highly flowable, non-segregating concrete that can spread into place, fill formwork, and encapsulate even the most congested reinforcement by means of its own weight, with little or no vibration. It delivers these attractive benefits while maintaining or enhancing all of customary mechanical andSelf-Compacting Concrete SpringerLink

As a result, self compacting concrete has been used in many practical structures. The first application of self compacting concrete was in a building in June 1990. Self compacting concrete was then used in the towers of a pre stressed concrete cable stayed bridge in 1992. Since then, the use of self compactingSELF COMPACTING CONCRETE. INTRODUCTION. A. special type of concrete of flowing consistency. Developed initially in Japan in 1980s to offset the growing shortage of skilled labour.

Self-compacting concrete (SCC) is a development of conventional concrete, where the use of vibrators for compaction is no more required. Formulating SCCs is a compromise between adequately high fluidity to ascertain good casting and an adequate consistency to eschew phase separations quandaries (segregation or bleeding).To address the problem of low accuracy and poor robustness of in situ testing of the compressive strength of high-performance self-compacting concrete (SCC), a genetic algorithm (GA)-optimized backpropagation neural network (BPNN) model was established to predict the compressive strength of SCC. Experiments based on two Prediction of the compressive strength of high-performance self

Abstract. 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.This study presents the effect of incorporating metakaolin (MK) on the mechanical and durability properties of high strength concrete for a constant water/binder ratio of 0.3. MK mixtures with cement replacement of 5, 10 and 15 % were designed for target strength and slump of 90 MPa and 100 ± 25 mm.
