Keyword Self compacting concrete, Metakaolin, Flyash, mix design, simple tool 1. Introduction In Japan, in early eighties, premature deterioration of concrete structures were detected almost everywhere in the country. The main cause of the deterioration was recognized as inadequate compaction. In addition, the

The existing procedures for self-compacting characteristics are those, which measure height differences at Design for Self-Compacting Concrete Library of JSCE, no 25, June 1995, pp 107-120. K Takada, G I Pelova and J C W Walraven. of

Jul 06, Self compacting concrete should be mixed in a forced action mixer, such as a paddle or drum type mixer. The mixing time will vary depending on the type of concrete and the amount of superplasticizer used. The concrete should be mixed until it is

Nov 04, for self compacting concrete (SCC) mix design with of coarse aggregate, replacement of cement with Metakaolin class F flyash, combinations of both controlled SCC mix with 0.36 ratio(by weight) 388 of cement paste volume. Crushed granite stones of size 16mm

Nov 06, so this mixture design is based on the following fundamental (a) ca of the concrete is kept at of the solid volume of concrete, (b) fa is kept at of the mortar volume, (c) ratio is normally assumed as by the volume depending on the powder and (d) the dosage of sp and the final required ratio are

May 03, Several methods of designing mix proportions for the self compacting concrete were developed by researchers in the last few decades Materials used in self

Oct 17, In the mix design procedure, the flowability can be optimized to balance the performance requirement and mix robustness. An enhanced mix design method of self-compacting concrete with fly ash content based on paste rheological threshold theory and material packing characteristics. Constr. Build. Mater., 234 (2020), Article

May 26, Normally concrete mix design is based on As there is no indian code available for self compacting concrete mix design, it is designed based on EFNARC specifications. Mix design for self compacting concrete is given as

Jan 01, Mix design of the self-compacting concrete 337 Time was measured for the concrete to reach a 500 mm spread circle (denoted by T50m) and the final diameter of the concrete in two perpendicular directions was measured (the average value is

The paper presents an experimental procedure for the design of self-compacting concrete mixes. The test results for acceptance characteristics of self-compacting concrete such as slump J-ring, V-funnel and L-Box are presented. Further, compressive strength at the ages of 7, 28, and 90 days was also determined and results are included

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 it becomes necessary to evolve a procedure for mix

This paper proposes a mix design procedure for self-compacting concrete (SCC) to achieve target mean compressive strength, in which mixes are designed on the basis of Indian Standards suitable adjustments are done as per the previous studies

procedure for the design of self-compacting concrete mixes. The relative proportions of key components are considered by volume rather than by mass. A simple tool has been designed for self compacting concrete (SCC) mix design with of coarse aggregate, replacement of cement with Metakaolin and class F

Oct 12, The multiscale rheological threshold theory can guide the mix design of self-compacting concrete (SCC) from a trans-scale view. Through the paste thresholds calculated by the
