Engineered Cementitious Composite (ECC) is a high tensile construction composite. This is using worldwide as an alternative of other composites due to its characteristics. This has properties such as early strength, self-healing and strain hardening nature, etc. The materials which are involving in the preparation are responsible for that but high cement content may lead to global warming due to emission of co2 into the environment. To avoid this, Pumice stone powder of 0%, 5%, 10%, 15%, 20%, and 25% was investigated. The properties of ECC with fly ash to cement ratio (F/C) is 1.6 was studied. The specimens were cased and cured for7, 14, and 28 days to study the mechanical characteristics and impact on early strength. Flowability of ECC increased with increasing of pumice stone powder.7 days cured specimens showed the decrease in the strength with increasing dosage of pumice stone due to slow pozzolanic action. Later the strength increased with increasing curing period and the optimum at 10% pumice stone powder.
