説明

In the case where concrete is placed at places requiring high durability, the LCA method has made clear that placing durable high-strength concrete is more effective in reduction of environmental burden than placing ordinary concrete a few times. It has also been found that preparing of high-strength concrete by mixing an ettringite-formed high-strength additive makes it possible to decrease the unit weight of cement requited to attain a designed strength, thus further contributing to reducing environmental burden. Owing to its decreased unit weight of cement, the high-strength concrete produces less amounts of fines when crushed and, therefore, can probably be recycled in full as aggregate.
