Sealants between elements of aerated concrete
(1980) In International Journal of Cement Composites and Lightweight Concrete 2(1). p.43-47- Abstract
- Because of the low tensile strength of aerated concrete, the sealing of joints between such elements causes special problems.
In this paper some main characteristics of sealants for use in aerated concrete joints are discussed. These properties are elongation resistance, elasticity, and ageing. The elongation resistance was examined at different rates and different temperatures. The elasticity was determined by measuring the residual deformation after a certain elongation. Storing in heat (40°C or 70°C) was used for accelerating ageing.
Of ten sealants, only four were found to be suitable in aerated concrete joints. Many of the disqualified sealants showed defective ageing properties or high resistance...
