Summary:

The material of slurry walls in river levees in order to satisfy role, have to be resistant on outside factors also frost penetration. This resistance decide on compressive strength and indirect about stability river levees. This article present laboratory tests connected with the influence of cycles frost penetration on selfMagdalena hardening slurries compressive strength. The tests were performed for samples of two materials i.e. used for slurry walls build by deep soil mixing method and cut-off method. The results of tests shown that self-hardening slurries undergo a deformation and destruction under frost penetration influence, which result is strength decrease of slurry walls material. The highest decreases were observed in cycles frosting and defrosting samples in full water-saturated conditions.
