Dear Mr. Collins:
Comanche Peak Project is undertaking a test program to provide additional data on the perfonnance of Richmond Inserts.
This letter provides a general outline of the physical testing to be performed at Comanche Peak on 1 1/2" diameter Richmond Type EC-6W inserts for shear strength.
Generally the test will be performed in accordance with ASTM E-488-76.
Nine specimens will be tested by the following methods:
A) Three specimens will be tested with the shear load plate attached directly to the insert by an ASTM A-490 bolt.
B) Three specimens will be tested with the shear load plate separated from the insert by a one inch shim plate and employing an ASTM A-490 bolt.
C) Three specimens will be tested with the shear load plate l
separated from the insert by a one inch shim plate and employing an ASTM A-307 bolt.
These tests will be performed on inserts which have been placed l
in a concrete test slab. Appropriate quality control records are l
being maintained on the concrete, which was placed on February 11, l
1983.
The tests are anticipated to be run on the week of March 21, 1983.
If you have any further questions, please contact Mr. R. M. Kissinger l
