This study is a series of studies intended to derive the improvement of strength concrete quality using an emulsified refined oil (ERCO). In other words, ERCO is used to analyze the improvement degree of the basic properties of ordinary strength concrete by pre-adding the AE Agent on its products. ERCO was also planned to have a mixing ratio of 0, 0.5 %, and the pre-addtion of AE agent mixed with 0, 1, 2, and 3 % of the concrete's mixed ERCO mass. As a result, as the pre-injection of AE agent was increased, the slump, and air contents tended to be improved microscopically, but there was no significant effect. and Compressive strength tends to increase smart-all as the pre-addtion of AE agent increases in concrete, but it does not have a significant effect.
