Abstract:

SP29 Emphasis is placed on the importance and acceptance of structural lightweight concrete on the construction scene. Increased interest in the use of lower density concretes, in some of the building systems developed to alleviate the housing shortage and the peculiar properties of these materials, such as energy absorption; which makes them attractive for uses other than conventional building construction, add to the significance of this publication.

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.

Abstract:

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.

Publication:

Symposium Papers

Volume:

29

Abstract:

This paper presents data on the fire resistance of concretes having oven dry unit weights in the range of 30 to 100 lb per cu ft (500 to 1600 kg/m3). . .Design charts for estimating the fire endurance of two-cource floors and roofs are discussed. Relationships between moisture content and relative humidity of fire test specimens are presented.
