A method of making the same includes: weighing enough water, adding microcapsules of urea formaldehyde resin into water and stirring until the microcapsules disperse sufficiently; adding the mixture into a mixing vessel, adding cement in corresponding mass into the vessel; stirring; adding filler materials including sands, stones etc; casting in the field with 1/3 of the total mass each time; vibrating and expelling the air therein until mould fills with slurry. The microcapsules release epoxy resin during their brokenness, then the latter has chemical reaction with solidifying agent in micro cracks to repair defective structure. Thus the invention reaches the result of self diagnosing and repairing micro cracks in concrete, preventing their spread, maintaining mechanical configuration of buildings. It has great economic value and environmental value.

Targeted delivery of concrete admixture

A sheet 100 of water-soluble material such as polyvinyl alcohol comprises a plurality of individual, sealed pockets 110 , each containing concrete admixture. The sheet is cut to size and attached to the interior of a formwork structure 200 with, for example, PVA glue. After concrete is poured into the formwork, covering the sheet 100 , the sheet dissolves, releasing the admixture onto the surface of the concrete as it sets. In another arrangement, a sealed container 300 formed from a water-soluble material contains concrete admixture. The external wall of the container has a plurality of regions 320 where a thickness of the wall is reduced. The container is attached to interior walls of a formwork structure 200 or to reinforcing bars inside a formwork structure. After concrete is poured into the formwork, submerging the container, the container dissolves, with the thinner regions dissolving sooner, releasing the admixture into the concrete.
