“…Accordingly, regardless of the age of concrete, increasing the percentage of MK from 18% to 36% did not show a significant effect on compressive strength. These results are in agreement with the findings of the other researchers [7,[37][38][39][40].…”

h i g h l i g h t sSeveral amounts of SCM were used as binary, ternary and quaternary blends in SCC. Silica fume, Class C and F fly ash, metakaolin and slag were studied in one paper. Good correlation was established between permeable voids and water absorption rate. SCM reduced the permeability of almost all mixtures. Class C fly ash improved the permeability better than Class F fly ash. a r t i c l e i n f o b s t r a c tIn this study, permeability properties of 17 self-consolidating concrete (SCC) mixtures containing various supplementary cementitious materials (SCM) were investigated by different experimental approaches. The effects of SCM type and content on the compressive strength, rapid chloride ion permeability (RCPT), water penetration depth, water absorption and sorptivity were studied. For these purposes, various amounts of silica fume (SF), metakaolin (MK), Class F fly ash (FAF), Class C fly ash (FAC) and granulated blast-furnace slag (BFS) were utilized in binary, ternary, and quaternary cementitious blends. Results showed that partial replacement of PC by SCM increased the compressive strength of control mixtures at 28 and 90 days (except for FAF at 28 days). Mixtures containing MK presented a better performance compared to other SCM at 7 days. The utilization of SCM reduced the RCPT results of almost all mixtures compared to the control mixtures and the reduction was more significant with an increase in the SCM content. All of the mixtures containing SCM had lower penetration depths when compared to reference mixtures at 28 and 90 days. Good correlations were established between the percentage of permeable voids and water absorption. Moreover, there was an inverse but almost linear relationship between permeable voids content and compressive strength of the mixtures.

“…Nowadays, the most widely used pozzolanic materials are industrial by-products, and their use in binder composition can contribute to the reduction of OPC consumption, exploitation of raw materials and, consequently, a reduction in the carbon footprint associated with Portland cement-based products. Among the pozzolanic materials, fly ash (FA), metakaolin (MK) and silica fume (SF) are the most used materials [3][4][5][6][7][8]. The main advantage of using these kinds of material, besides the increment on the mechanical strength, is that they can improve the durability aspects of concrete and mortars such as freeze-thaw resistance, chloride ingress and sulphate attack [9,10].…”

“…Dinakar and Manu suggested a SCC mix design method using an efficiency concept for different percentages of metakaolin as depicted in Figure . The strength of SCC at replacement percentages 7.5, 15, and 22.5% was 80, 100, and 120 MPa, respectively with a fixed powder content of 550 kg/m 3 .…”

Self-compacting concrete (SCC) was developed in 1988 and introduced by Professor H. Okamura to achieve durability of structures with low skilled laborers. The three properties of SCC that differentiates it from traditional concrete are passing ability, filling ability and segregation resistance. The present study highlights the developments concerning SCC in the period from 1995 to 2017. This information is important for researchers and professionals working in this area. SCC can be optimized to a larger extent to find the best alternative either by use of additives or tailor-made mix design. Based on different principles and parameters, design methods can be categorized into six classes namely empirical design method, statistical factorial design method, strength-based design method, rheology of paste method, particle packing method and Eco-SCC mixture design method. To develop SCC with high quality a suitable method can be chosen depending upon the situation and application.compressive strength, design mixture method, empirical, particle packing method, rheology of paste method, self-compacting concrete 1 | INTRODUCTION SCC flows into every corner of a mold, passes reinforcement and fill gaps without any need of internal or external vibration and compaction simultaneously maintaining stability without segregation and bleeding of concrete. It has the ability to compact itself only by means of its own weight. [1][2][3][4] In the early 1990s, SCC was introduced in concrete technology. 5 The properties of SCC depend on the source and the type of constituent materials and their properties. 6 The use of SCC eliminates the compacting effort and this results in reduced costs of placement, moreover, a decrease in the duration of construction improves productivity. 7 SCC is a concrete type with high workability, a high flowability and superior resistance to segregation. 8 The property of SCC to completely fill a formwork by filling gaps and to flow around reinforcement without the need of vibration or bleeding makes it significant to use. 9 A good balance between deformability and stability resulted in the successful development of SCC. Different mix design procedures were proposed for SCC that include (a) combinations of a higher volume of mineral additives and water-reducing admixture, (b) combination of water-reducing admixture and viscosity modifying agent. 10 The use of SCC reduces the noise during casting and provides better working conditions. 7,11 The applications of SCC in densely reinforced sections, that is, columns and beams in moment-resisting frames in seismic areas is necessary to ensure that all gaps in a formwork are filled. 7 The use of limestone powder as a fine additive can improve the rheological behavior of cement pastes and the combination of both limestone powder and fly ash can result in a higher packing density. 12 Eco-SCC is a SCC with a maximum total binder content of 315 kg/m 3 which can include cement, silica fume, fly ash and/or limestone filler. 13 Air-entrained SCC was designed with the u...
