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.

This paper surveys the factors governing the design of insulating concrete roof decks. Factors affecting design considerations are multiple, ranging from aesthetic to technical. This paper deals only with the technical design considerations of roof deck systems made of steel centering or forms with a low-density concrete overlay. This type of concstruction represents the majority of low-density concrete roof deck usage, other than concrete used for roof fills.

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.

Tests were made at the Portland Cement Association Laboratories regarding the elastic and time-dependedt shortening of reinforced lightweight concrete columns which were fabricated and loaded to simulate construction conditions encountered in a 50-story concrete building 714 ft (218 m) tall. The measured data from these incrementally loaded columns show low creep when the load is applied at a realistic rate. A 3-year field investigation of the actual structure will be undertaken and comparision between laboratory and field data will be made. Such comparisions wil provide data toward developing improved design concepts for ultra-high-rise concrete buildings.
