Concrete Under Arctic Conditions
In the research, strength and deformation properties of concrete under very wide temperature variations were studied, particularly changes in the compressive strength and modulus of elasticity of various concretes. These changes were studied by testing air-entrained concretes, non-air-entrained concretes and concretes containing hollow plastic microspheres. The frost-resistance of concrete was tested at temperatures ranging from +20 C to -65 C. The hardening of concrete at a temperature of -10 C and the effect of this of the precuring period, when different anti-freeze admixtures are used, was studied experimentally. Test on hollow-core slabs for cold brittleness at -30 C were carried out and their complete maintenance of impact ductility was verified.
