Özet
Concrete with special features of self-curing had assisted in ameliorating the problem of improper curing in construction industries. This study evaluated the use of Propylene Glycol (PG) in the compressive and flexural strength of self-curing concrete. Concrete grades M15, M20, and M30 were batched by weight, and propylene glycol was added to the mix, within the dosage of 0.5, 1.0, 1.5, and 2%, respectively. Concrete cubes and prisms of sizes 150 × 150 × 150 mm and 100 × 100 × 400 mm were cast from the mixtures and allowed to cure internally in the open air for 28 days to produce Propylene Glycol Self-Cured Concrete (PGSCC). Two control samples were cast without PG addition, cured by ponding and open air for 28 days to produce Open-air Cured Concrete (OCC) and Ponding Cured Concrete (PCC). Compressive and flexural strength tests were conducted on the PGSCC and control samples. PGSCC had compressive strengths of 18.67, 22.40, and 31.29 N/mm2 and flexural strengths of 3.24, 3.55, and 4.20 N/mm2 compared to the control’s compressive strengths of 16.41, 20.59, and 27.70 N/mm2 and flexural strengths 3.03, 3.43 and 3.95 N/mm2 for concrete grade M15, 20 and 30, respectively. Propylene glycol addition within the dosage of 0.5 to 1.5% in concrete improves the compressive and flexural strength of concrete. The use of propylene glycol was found to be effective and a good agent for self-curing concrete technology.
