Abstract
Curing plays a crucial role in achieving the desired strength, characteristics, and durability of concrete. Negligent curing practices can lead to adverse effects on hydration and mechanical properties of concrete. In recent times, self-curing concrete has gained significant attention due to its potential in reducing water loss through the use of self-curing agents. The Present Research study focus on investigation on durability characteristics of self-curing self-compacting concrete using crushed rock powder and mineral admixtures. The objective of this research is to evaluate the durability properties of SCC, for M25 and M40 grade inclusive of effectiveness of mineral admixtures and self-curing agents at varying dosages. Two self-curing agents, Polyethylene glycol (PEG-400), at dosages of 1%, 1.5%, and 2%, and Superabsorbent Polymer (SAP), at dosages of 0.1%, 0.2%, and 0.3%, respectively, were utilized. The mineral admixture dosages were based on the SCC mix design. Various standard tests, including conventional slump, T50cm slump, J-ring, V-funnel, U-box, and L-box, as per EFNARC, were conducted on the specimens. Furthermore, the durability properties, such as water absorption, resistance against acid attack, and sulphate attack, were evaluated by comparing them with those of conventional normal concrete (CNC) as per IS 10262 and normal self-compacting concrete (NSCC) without self-curing agents. The curing process for CNC and NSCC followed conventional methods at ambient temperature under laboratory conditions, while self-compacting concrete incorporating self-curing agents underwent curing in air at ambient temperature. The results showed that the durability properties of self-curing concrete were significantly improved with the inclusion of 0.3% SAP mixtures, outperforming PEG-400 for M25 and M40 grades of concrete. Moreover, the addition of fly ash and silica fume to the cement mixture enhanced the resistance of the concrete, indicating improved pore structure and greater durability.
Keywords: Water Absorption, Acid attack, Sulphate attack, Fly ash, Silica fume and Self-Curing agents.
