초록

This test investigates early strength and durability of concrete using early strength type materials(cement, Polycarboxylate acid). The goal of this test is to secure the strength of 5.0 MPa in 12 hours early age and strength of 14 MPa for 24 hours correspondingly. This type of admixtures, concrete curing temperature, amount of binder and other concrete properties were confirmed by experimental factors. Comparing outcomes from two cases on using early strength type materials and common materials resulted in reducing of costs and shortening of the construction period, that determined the economical benefits of using early strength materials in construction.
