Research overview:
Shingari Dam is a rock-fill dam under construction by Chugoku Regional Construction Bureau and about 100,000m3 of concrete is cast at flood outlets. This test examines whether or not material at the field is available as this aggregate for concrete. In the fiscal 1999, we examined on freeze/melt durability of materials at the field, following the fiscal 1998, and confirmed them usable as aggregate for concrete. Also, coagulation of fresh concrete tends to be promoted with influence of clay minerals contained in aggregate, so we confirmed effectiveness of ultra-retarding agent as its countermeasure.
