One of the biggest oyster farms on the side of the Japan Sea are Nakashima-machi
and Anamizu-machi, both located in the Noto Penninsula, Ishikawa Prefecture.
With a view to promoting the industries of Ishikawa Prefecture, the reuse
of large amounts of oyster shell resources has become an important issue.
This study was carried out for the application of the oyster shell resources
to civil engineering materials. Based on our laboratory experiments, oyster
shell was used as a field test in a road broadening construction at Nakashima-
machi whose soil is soft in its great part. The following results, confirming
that oyster shell could be applied as civil engineering materials, were
obtained
| (1) |
The moisture absorption ability of oyster shell
increases as it is milled into small pieces because of its micro-pores.
It suggests the effective way of the addition of oyster shell to
soft soil. |
| (2) |
The unconfined compressive strength is improved
by the use of oyster shell and hardening material. |
| (3) |
In the field test of the road construction, the
improvement in the mechanical strength by the moisture absorption
effect of milled oyster shell was recognized. |
