The Foam Concretes on the Activated Mixing Water
The paper presents the results of studies of the physical and mechanical properties of foam concrete on activated mixing water. Corrosion resistance of reinforcing steel in foam concrete with the use of activated water in the presence of mineral additives was studied. The use of activated with the electromagnetic field and electric current water of mixing enhances strength characteristics and reduce shrinkage deformation of composites. The increase of water resistance of foam concretes prepared on activated water of mixing compared with control compositions it was established. The comparative characteristic of foam concrete on the two types of foaming agent is given. The results of the anodic behavior of steel in activated water, characterizing the degree of aggressive influence on the steel depending on the activation mode and the chemical composition of mineral additives. This paper is a revised version of the paper (study) published earlier in the proceedings of the Creative Construction Conference 2018 (Karpenko et al., 2018).
