A review: Mechanical Properties of Self-Compacting Concrete (SCC) and Influential Factors

Abstract

Self-compacting concrete (SCC) has emerged as a promising construction material due to its unique characteristics of high flowability and self-leveling ability without needing external compaction. In this study, the mechanical properties and influential factors of SCC were analyzed to determine their impact on the overall performance of the material. The properties analyzed included compressive strength, flexural strength, split tensile strength, and modulus of elasticity. The influential factors included the water-to-binder ratio, type and dosage of superplasticizer, aggregate size and shape, and curing conditions.

The results of this study indicate that influential factors greatly influence the mechanical properties of SCC. A lower water-to-binder ratio leads to higher strength and lower permeability of the material. The use of a high-range water-reducing superplasticizer in the proper dosage can significantly enhance the workability and strength of SCC. The size and shape of aggregates can also affect the flowability and homogeneity of SCC, with smaller and more rounded aggregates yielding better results. Proper curing is critical to achieving the desired properties of SCC, with moist curing being the most effective.
