Assessing Semiflowable Self-Consolidating Concrete with Sugarcane Bagasse Ash for Application in Rigid Pavement.

Semiflowable self-consolidating concrete (SF-SCC) is a new type of self-consolidating concrete with flowability, green strength, and shape-holding ability in the fresh state. SF-SCC is cost-effective, energy-efficient, and low-carbon-footprint concrete because vibrators can be eliminated. This paper discusses the fresh, strength (compressive, splitting tensile, and flexure), durability (chloride ion penetration, water absorption, and water penetration), and microstructural properties of SF-SCC mixes with sugarcane bagasse ash (SCBA) as the cement replacing material at 10%–50% by weight of cement. The results show that all the mixes complied with the requirements of fresh properties of SF-SCC. The strength and durability results were used to validate the suitability of such SF-SCC mixes for rigid pavement construction as per the specifications of the Indian Roads Congress (IRC). It can be concluded that the mixes with as much as 40% SCBA can be used in urban roads. All the mixes with as much as 50% SCBA can be used in the construction of road pavements in the interior part of rural areas, i.e., village roads. The study also involved Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) analysis for ranking of the mixes. [ABSTRACT FROM AUTHOR]
