Abstract:In 1939, at the navy’s new David Taylor Model Basin at Carderock, Md., there was an urgent need for a non-shrinking bearing material to be used under the cast-steel "chairs" which support the rails on which the towing carriages run. Requests for information concerning materials and installation procedures produced such varied answers that investigation was started to find the best material and the best procedures for placing it. The bearing material selected for use was 1:3 portland cement mortar, with 4.13 gallons of water per sack of cement. This was rammed firmly into place. This bearing material has now been in place over a period of some 9 years under extremely severe conditions and without exception has proved to be excellent in function and condition.
