Mechanical Properties and Self-Healing Effect of Concrete Containing Capillary Hydro Insulation Admixture

Abstract

Abstract Crack formation during exploitation considerably decreases durability of concrete structures. Capillary hydro insulation is an integral crystalline waterproofing system ensuing filling of micro cracks, pores and capillaries with an insoluble crystalline formation. In order to evaluate self-healing effect of this system, fiber concrete beams were initially pre-cracked, then treated with capillary insulation and repeatedly tested under bending. Water permeability and frost resistance tests were also realized in order to evaluate long-term performance of the capillary insulation.
