The objective of this study is to compare the mechanical properties, that is, compressive, split tensile and flexural strength of smart concrete with the conventional concrete (M-30 and M-40). Few studies have been conducted to study the mechanical properties of Self Compacting Concrete (SCC) with self-curing capabilities. In this study, trial mixes were prepared for SCC by using Sulfonated Naphthalene Formaldehyde (SNF) powder in varying proportions from 0.5% to 1.0% to arrive at optimum SNF dosage to achieve the required workability, measured in terms of slump. Polyethylene Glycol 4000 (PEG-4000) was used as self-curing agent in dosages varying from 0 to 1.25 % with the already obtained optimum dosage of SNF to prepare concrete mixes. Concrete cubes, cylinder and beams were cast with M-30, M-40 and various SCC mixes prepared with SNF and PEG-4000. The specimens were then tested for compressive, split tensile and flexural strength after 7 and 28 days. The specimen with 0.75% PEG4000 showed highest compressive strength in comparison to all other mixes both after 7 and 28 days. Split tensile and flexural strength was highest for conventional M-40 mix with respect to other mixes.
