Document: 

SP39-01

Date: 

January 1, 1973

Author(s):

Carl Berwanger and A. Faruque Sarkar

Publication:

Symposium Papers

Volume:

39

Abstract:

The thermal coefficient of expansion and the dynamic modulus of elasticity of concrete have been determined under short-term steady state temperatures, -100 to 150F (-73 to 66C). Specimens were cured both saturated and air-dried in the laboratory and tested at 7, 28, 84 days at at one year.

Abstract:

SP39 A discussion of Canadian research into effects of below normal and above normal temperatures on properties of concrete. The raction of temperature and age on thermal expansion and modulus of elasticity of concrete; vacuum processing; pulse velocity; field curing and protection are covered. Also included are effects of heat applied during curing and after placement, effects of steam injection and review of research by National Research Council of Canada on fire endurance of concrete masonry walls.

Abstract:

Two series of lightweight concrete mixes made with expanded shale and slag aggregates were prepared for heat exposures between 300 C and 1000 C (572 F to 1832 F)/ To some concretes microfillers such as fly ash, silica flour, and calcined shale dust were added to replace 25 and 40% of the portland cement in the binder.

Date: 

January 1, 1973

Author(s):

T.Z. Harmathy

Publication:

Symposium Papers

Volume:

39

Abstract:

A review is presented of the work carried out in the author's laboratory over the past ten years concerning the fire endurance of concrete masonry walls. After defining fire endurance, the author surveys the material properties of concrete and the geometric features of the component units that affect the performance of concrete masonry walls in fire.

Abstract:

The effect of freezing temperatures on the compressive strength and ultrasonic pulse velocity of vacuum processed and nonprocessed concrete was investigated for two concretes with initial water/cement ratios of .71 and .45.
