“…The value of slump also changes as the constituents of the SCC mix changes. When the SCC mix was incorporated with fly ash, it had been observed that the average value of slump was found to be 655 mm [2]. In other study conducted by H.Y.…”

“…The value of the J -Ring test is observed to be 4 mm -10 mm when fly ash was added in the SCC mix in different proportions [2]. In the other study, it was concluded that the magnitude of J -Ring was nearly 6.35 mm [51].…”

“…Also, compressive strength of SCC was affected by using different percentage of VMA. It had been observed that by increasing the percentage of VMA upto certain limit increases the compressive strength and then, it starts reducing gradually [2]. As per F. Alhussainy et al [39], if the strength in compression of SCC incorporated with FA was measured by considering 3 cylinders of 100 mm diameter and 200 mm height in accordance to AS 1012.9 [40], then its outcome of the test depicted that the average compressive strength comes out to be 57 MPa.…”

“…When the steel fibres added into the Rheodynamic concrete mix in the different quantities of 60 kg/m 3 , 30 kg/m 3 and 0 kg/m 3 , the Vfunnel test value was found to be 9.06 seconds, 9.74 seconds and 15.33 seconds respectively [47]. The magnitude of the V -Funnel test was found to be 7 seconds -12 seconds when fly ash was added in the SCC mix in different proportions [2].…”

The most important material which is used for the construction of any concrete structure is concrete itself. It is considered to be as a versatile construction material as its properties can be changed by various means, with the help of different elements and as and when required. Rheodynamic Concrete or Self-Compacting Concrete is a special form of concrete which can easily flow into any kind of formwork uniformly, without facing the problem of bleeding and segregation, gives a better finish, has a great characteristic of placement, requires no vibration, and thus gives a safe working environment. Due to a number of merits, this type of concrete had becoming popular in the construction work. Simultaneously, the big industries across the world are producing the by products such as fly ash, rice husk ash, etc. Thus, this paper represents a review, which is done to incorporate these wastes by – products in Self-Compacting Concrete and observe, how the different properties of the same has been modified effectively and efficiently.

“…As mentioned in the introduction, a fixed optimum quantity of 2.1 kg/m 3 of glass fibres is used in all the SCC mixes for the best results [16]. PVA fibres are well-suited for a wide variety of applications because of their superior crack-lighting properties, high modulus of elasticity, excellent tensile and molecular bond strength, and high resistance to alkali, fatigue, and abrasion [5], [16][17][18], [28]. In the experimental tests, the amount of PVA fibres is also kept fixed to 2.1 kg/m 3 to have better hardened properties [16].…”

Self-compacting concrete (SCC) being an innovative and environmentally friendly concrete is impressively accepted in various regions of the world. SCC is a high-performance concrete that can consolidate under its own weight without the aid of mechanical vibration, filling spaces of almost any size and shape without segregation or bleeding. In this study, experimental investigations were carried out to improve the properties of self-compacting concrete by replacing cement with various percentages of Micro silica in SCC having fixed percentages of fly ash, glass, and polyvinyl alcohol fibre. Micro silica content varied from 2% to 10% by weight. Various tests like L-Box, V- funnel, Slump flow, and uniaxial compression tests were carried out on SCC, and the results have been compared with the control mix. It is observed that the hardened properties of the SCC improved with the addition of micro silica. However, the filling ability, passing ability, and resistance to segregation of fresh concrete mix with increasing micro silica content were found to reduce.
