| Research Abstract |
In late years, the opportunities to use the materials which were made from by-products increase in the concrete industry all over the world. In such background, we pay attention to eco-cement, fly ash and recycled aggregate. In this study reports the results of the experiments designed to clarify the strength properties of the concrete used these materials. At the water-cement ratio of 0.65 - 0.20, the compressive strength of eco-cement concrete dropped by mixing recycled aggregate class M. This drop was relatively small at the compressive strength less than 60N/mm2, and was remarkable at the compressive strength more than 60N/mm2: lower limit of ultra-high strength concrete.
