“…In the hardened state also it is dense, homogeneous, same mechanical properties and durability properties as traditionally vibrated concrete [1]. Mushtaq Ahmad et al [2] has investigated M35 grade concrete as a partial replacement of quarry dust with fine aggregate ranges from 0% to 40% and concluded that 30% replacement have better workability. S.Premkumar et al [3] experimentally investigated the mechanical properties of river sand with a replacement of quarry dust upto 100% and concluded that strength of concrete improves in 100% replacement.…”

Self-compacting concrete (SCC) is a concrete which flows under its own weight in the congested areas without any external force. Increase in demand and decrease in availability of fine aggregates, we use an alternative material called quarry dust, it is a finer material generated from stone quarries. This paper deals with the feasibility study on the utilization of quarry dust as a partial replacement in fine aggregate. In this experimental investigation, the properties of materials are tested as per Indian standards. The filling ability, passing ability and flowability characteristics of SCC as a partial replacement of fine aggregate with quarry dust was investigated as per EFNARC guidelines. In this experimental investigation, different mixes were prepared as a partial replacement of fine aggregate with quarry dust at various percentages such as 10%, 20%, 30%, 40% and 50% to obtain the optimum replacement level. The Slump flow, U-box, L-Box, V-Funnel and J-ring tests were carried out to determine the workability of SCC. The finding shows that the workability decreases with the addition of quarry dust. It is concluded that addition of quarry dust reduces the fresh properties of the SCC.

“…SCC significantly reduces the placement time of concrete in the large section due to easy handling technique. Self-compacting concrete (SCC) may reduce the noise on the worksite caused due to the vibrator use for concrete compacting purpose [1]. In the modern construction demand for concrete material has increased.…”

“…The use of fly ash reduces the demand for cement, fine fillers and sand, which are required in high quantities in SCC. Fly Ash has been shown to be an effective addition for SCC providing increased cohesion and reduced sensitivity to changes in water content [1]. The durability of concrete subjected to aggressive environments depends largely on transport properties.…”

“…Significant improvement in the properties of SCC has seen by the addition of fly ash. Past studies [1], [2], [6], [8]- [12] concluded that water absorption has strong relation with the voids present in the concrete and voids carries fluid in the result absorption in the concrete increase. Fly ash incorporated with SCC resulted higher water absorption values compare to other materials.…”

Self-compacting concrete or also known as self-consolidating concrete (SCC), an innovation in concrete technology is being regarded as one of the most promising developments in the construction industry due to numerous advantages that it has over conventional concrete. The cement and sand consumption in concrete production can be reduced by using a combination of industrial waste materials like fly ash and quarry dust and at the same time lead to energy and cost reduction. In this project, work is done on experimental study on fresh and hardened properties of SCC such as slump flow test, J-ring test, water absorption test, and compressive strength test of M35 grade of SCC. Five mixes with different percentages of quarry dust (0%, 10%, 20%, 30%, and 40%) as partial replacement for sand and a constant 10% of fly ash as partial replacement for cement is considered. The test results for water absorption and compressive strength were carried out after 7 days and 28 days of curing. The results obtained showed that the optimum dosage of quarry dust was 30% and that incorporating QDFA in SCC as green, sustainable and eco-friendly materials in SCC resulted in high workability, enhanced the strength and durability properties in term of water absorption.

The present study aims to investigate how the use of high‐range water reducer (HRWR) and variations in water/cement (W/C) ratio affect the properties of self‐consolidating concrete (SCC) while taking into account different proportions of polypropylene fibers (PF) and natural zeolite (NZ). A total of 28 samples were cast and analyzed. PF fractions ranging from 0% to 1.5% by weight were added, along with a substitution of 10% NZ for cement (50 kg/m3). Four W/C ratios (0.30, 0.35, 0.40, and 0.45) were tested, in addition to seven HRWR contents ranging from 5 to 6.5 kg/m3. Various tests were conducted to assess slump, T500, V‐funnel, L‐box, modulus of elasticity, and compressive, tensile, and flexural strengths. Novel models were developed to predict the properties of hardened concrete based on W/C, HRWR, PF, and NZ content. Findings indicated that optimal performance of PF‐reinforced SCC with NZ was achieved when up to 0.75% PF was combined with an HRWR content equivalent to 1.25% of the cement fraction and NZ ratio. Furthermore, the proposed models offer accurate predictions of both fresh and hardened‐state properties of PF‐reinforced SCC with NZ based on W/C and HRWR ratios.
