“…This effect caused enhancement in compressive strength and durability performance of SCC. Authors in [22] used three mineral admixtures namely SF (5% to 25%, increment 5%), MK (5% to 20%, increment 5%) and GGBFS (25% to 100%, increment 25%).The results were compared with normal concrete of 60MPa. Water-binder ratio was obtained as 0.4 with optimum dosages of SP and VMA as 2.3% and 0.15% weight of cement respectively.…”

Self-compacted concrete (SCC) is cast in the formwork without compaction and it fulfills the formwork due to its own weight. SCC is considered to have many advantages in comparison with conventional concrete like improved construction quality, faster construction activity, reduced cost etc. SCC is produced with the same ingredients of normal concrete. However, cementitious materials are also adopted to replace the cement content in SCC in order to use waste materials from industries and agricultural products. To further enhance the performance of SCC, different types of fibers are tried in order to produce fiber reinforced SCC. The fibers in the concrete bridge the cracks and diffuse the crack propagation which improves mechanical properties. In developed countries SCC has reasonable acceptance in construction industry but in developing countries like Pakistan has not gained acceptance. This paper is focused on undertaking a review of SCC with cement replacement and fiber reinforcement materials. The main objective of this paper is to compile the literature in order to understand the various properties of SCC in fresh and hardened state when these cement replacement materials and fibers are used.

“…Kavitha et al [17,18] reported that the incorporation of metakaolin in SCC improves micro and macro properties and enhances durability. Vivek et al [19][20][21][22] researched SCC using various mineral admixtures, namely silica fume, metakaolin, and GGBS in the binary mix and ternary combinations and also with natural and artificial fibers, and concluded that mineral admixtures had shown better performance when compared with control specimen.…”

This paper discusses the possibility of developing a lightweight self-compacting concrete (SCC) with self-curing capabilities. In this regard, a supplementary cementitious material metakaolin, a presoaked lightweight expanded clay aggregate (LECA), and a chemical agent, superabsorbent polymer (SAP), were incorporated in developing a self-compacting self-curing concrete possessing a target strength of 60 MPa through experimental investigations, and the results are reported. The research includes an analysis of basic material properties of constituent materials including fresh properties of concrete and mechanical properties such as compressive and splitting tensile strength. It was inferred from the experimental results that utilization of self-curing agents in SCC has enhanced the mechanical properties when compared with conventional SCC mix. In particular, a combination of 0.3% SAP and 15% LECA gave the optimum strength values. The optimum usage limit of both the materials is presented in this study, and the results prove that SCC can be used as an alternate resource without disturbing the natural resources.

“…2.3 Formulation of self-compacting mortar based on silica and limestone SCM can be considered as a two-phase material in which the sand is suspended in a very workable paste. According to several researchers, the behaviour of the SCM is strongly influenced by the type, the volume of sands and the fillers used (Yahia et al, 2005;Bouziani, 2013;Nepomuceno et al, 2014;Nécira et al, 2017;Vivek and Dhinakaran, 2017).…”

Purpose By its high fluidity, great deformability and rheological stability, the self-compacting mortar (SCM) is capable of ensuring the ability to be easily implemented without vibration. However, its formulation requires a large volume of fine materials with a high dosage of cement, which is necessary to ensure adequate workability and mechanical strengths, which is necessary to allow its flow. Current environmental considerations encourage reducing the production of cement, it is essential to use additions to replace the cement, because of their great availability and their moderate price. On another side, their use contributes to an economic sort to solve the problems related to the environment. Design/methodology/approach The formulations and characteristics of SCM made with two types of mineralogical sources (silica and limestone) were investigated. Different materials were used separately and in binary combinations; silica river sand (SRS), limestone quarry sand (LQS), silica fillers (SF) and limestone fillers (LF). The formulation starts with the self-compacting pastes (SCPs) then the SCMs at the SRS and the LQS whose the cement is partially replaced by volume contents of SF and LF with 15%, 30% and 45%. Findings The results obtained prove that the incorporation of LQS instead of SRS has a negative effect on the fluidity and deformability and a positive effect on the mechanical strengths of SCM. In addition, the incorporation of the SF and LF reduces the need for water and the saturation dose of superplasticizer in the pastes. Thus, the addition of the SF and LF in specific voluminal contents (15% SF and 30% LF) in the binder can have a beneficial effect on the parameters of the workability and the mechanical strengths of SCM. These results are very interesting to aspects such as technological, economic and environmental. Originality/value Influence of the different type of sands and fillers in improvements the properties of SCM made from various mineralogical sources.
