Abstract
Introduction. In world practice, self-compacting concrete is increasingly used, which has high workability without additional (vibration) efforts. Straining concrete is also known, which is capable of increasing in volume during hardening, and under conditions of limited expansion deformations, it can self-strain, creating its own internal stress state, which neutralizes the manifestation of shrinkage.
Aim. Determination of the abradability of concrete made from a dry, self-sealing, straining concrete mixture.
Materials and methods. Dry self-sealing straining concrete mixes were used. The determination of abradability was carried out according to State Standard 13087-81 using an abrasion circle.
Results. The results showed that the abrasion grade G1 (low) corresponds to the majority of samples, which indicates the high hardness of the material.
Conclusions. The high hardness of the material leads to low abradability, which makes it suitable for use in highload structures. Further investigation of the effect of various additives on the properties of self-sealing concretes is necessary.
