Replacement of Cement by Marble Dust and Alcofine

Abstract

The cement industry is one of the largest contributors to global CO? emissions, accounting for approximately 7–8% of anthropogenic carbon dioxide. This has driven significant research into supplementary cementitious materials (SCMs) that can partially replace ordinary Portland cement (OPC) without compromising—or while enhancing—mechanical and durability properties. Marble dust (MD), an industrial byproduct from marble processing, and Alccofine, an ultrafine slag-based material, have emerged as promising candidates. This paper reviews the current literature on the individual and combined use of marble dust and Alccofine as partial cement replacements, examining their effects on workability, compressive strength, durability, and microstructure. Findings suggest that optimized blends can achieve superior performance compared to conventional concrete while reducing environmental impact and production costs.

Introduction

This paper reviews the use of marble dust (MD) and Alccofine as partial replacements for cement in concrete to improve sustainability, performance, and cost-effectiveness. Since cement production generates significant CO? emissions, replacing a portion of cement with industrial byproducts offers environmental and economic benefits.

Marble dust, a waste product from marble processing, primarily acts as a filler material that improves particle packing, reduces porosity, and enhances workability at low replacement levels (5–10%). However, excessive replacement can reduce strength due to its limited cementitious properties. Alccofine, an ultrafine slag-based supplementary cementitious material, is highly reactive and improves early-age strength, long-term compressive strength, durability, and pore refinement. Optimal Alccofine replacement is generally found between 6–10%.

The review highlights that combining marble dust and Alccofine creates a synergistic effect. Marble dust improves packing density while Alccofine contributes pozzolanic reactions that generate additional C-S-H gel, resulting in denser microstructures and enhanced concrete performance. Studies show that blends containing approximately 10% marble dust and 8% Alccofine provide the best balance of workability, strength, and durability.

Experimental findings indicate that combined systems improve compressive, tensile, and flexural strengths while significantly reducing water absorption, chloride permeability, sorptivity, and acid attack. The enhanced durability makes these blends suitable for aggressive environments such as marine and coastal structures.

From an economic perspective, marble dust is much cheaper than ordinary Portland cement, and optimized MD–Alccofine blends can reduce binder costs by 8–12%. Environmentally, replacing around 18% of cement can lower embodied carbon emissions by approximately 14–15% and utilize substantial amounts of industrial waste, supporting circular economy objectives.

The review concludes that marble dust–Alccofine concrete is a promising sustainable alternative to conventional concrete. However, further research is needed on long-term durability, fire resistance, standardization of marble dust properties, advanced blended systems, and comprehensive life-cycle assessments.

Conclusion

This review leads to the following conclusions: 1) Marble dust effectively serves as a filler material at 5–15% replacement, improving particle packing and maintaining or slightly enhancing compressive strength. 2) Alccofine acts as a highly reactive pozzolanic and hydraulic material at 6–10% replacement, significantly improving both strength and durability. 3) Combined systems exploit synergistic particle packing and complementary reaction mechanisms, with optimal blends achieving 15–25% strength improvement and 40–60% durability enhancement. 4) The recommended blend for balanced performance is 10% marble dust + 8% Alccofine, enabling 18% cement replacement with superior properties. 5) Economic analysis indicates 8–12% cost reduction in binder materials, while environmental assessment suggests 14–15% reduction in embodied carbon. 6) These materials offer a practical pathway toward sustainable construction, transforming industrial waste into valuable resources while meeting or exceeding performance standards.
