SP29-12

Date: 

January 1, 1971

Author(s):

George C. Hoff

Publication:

Symposium Papers

Volume:

29

Abstract:

Low-density concretes having an oven-dry unit weight of 50 lb per cu ft or less have been successfully used as backfills for lined tunnels. . .Because of the permeable nature of these concretes, free water contact situations should be avoided. Suggestions for avoiding most problem areas are provided.

Symposium Papers

Volume:

29

Abstract:

A description of given of a series of tests with perlite, vermiculite, and cellular insulating concretes. . .There are significant differences in the drying shrinkages of the 3 types of concretes and also in the shrinkages of the concretes made from the 3 brands of perlite.

Publication:

Symposium Papers

Volume:

29

Abstract:

The current design concepts for some aspects of civilian and military construction include the provision for low-density concretes where the functional use of these concretes is for energy absorption, shock-wave reflection, controlled crushing strength levels, and large deformation capabilities. . .Special physical properties, determined when the concrete was in a constrained condition, are discussed and related to other physical property parameters.

SP29-04

Date: 

January 1, 1971

Author(s):

Vincent J. DeSimone

Publication:

Symposium Papers

Volume:

29

Abstract:

This article presents highlights of the structural analysis and design, as well as the quality and control of materials, in what is considered to be the largest circular concrete plate in the United States. A review of long term deflection control is presented with a view towards resolution of laboratory tests data in lightweight concrete with design and field practice.
