ABSTRACT

Introduction. Progressive cracking remains the principal cause of the reduced service resource of ce-ment and reinforced concrete structures, since a crack opening above the regulated threshold gives aggressive media direct access to the reinforcement and to the concrete body. Self-healing cements, in which the recovery of continuity is achieved through autogenous crack closure, mineral crystallising admixtures, or bio-mineralisation with calcium carbonate precipitation, are considered as a means of turning durability from a passive property into a controllable one. The aim of the work is to quantify how the kinetics of crack closure shifts the onset of reinforcement corrosion and how this affects the calculated service life. Materials and methods of research. The study is based on an original computational model that integrates two processes: the time-dependent closure of a single crack and the one-dimensional diffusive penetration of chloride ions toward the reinforcement, governed by Fick’s second law. The kinetics of closure is described by a decaying exponential with a width-dependent constant and a plateau of residual opening for cracks extending beyond the effective range. The regulatory framework was established in accordance with SP 63.13330.2018, which sets the limiting crack width at 0.3 mm for sustained opening and 0.4 mm for short-term opening for structures subject to durability requirements. The model element is represented by a monolithic wall of an underground structure with a thickness of 300 mm made of concrete class B30 grade W8 with a protective layer of 40 mm and working reinforcement A500 with a diameter of 16 mm. Results. An author's model of crack closure and diffusional chloride ingress was constructed for a model hydraulic element with the crack opening regulated according to SP 63.13330.2018. The model calcula-tion showed that at an initial width of 0.28 mm the residual opening after 28 days decreases to 0.041 mm, the water-tightness recovery coefficient reaches 0.86, and the corrosion onset shifts from 19.7 to 41.3 years. Conclusions. The result is most sensitive to the initial crack width, with a comparatively weak dependence on the mineralization rate. The obtained relations indicate that the self-healing effect is realized mainly within a narrow range of fine cracks, so that the design gain in resource is determined not so much by the activity of the admixture as by keeping the opening within the zone of effective closure.
