Abstract
The present application provides for water capsules, preparation methods of water capsules, a preparation method for lightweight concrete and a structure of lightweight concrete. Each of the water capsules comprises an alkali-sensitive shell and water inside; the water capsules are used to mix with a cementitious matrix, the water capsules can survive during concrete mixing and transportation processes but then gradually rupture in hardened concrete; the water released during the hardening of the concrete is beneficial for the hydration of the concrete. The water capsules and their preparation method, the preparation method for and structure of the lightweight concrete of the present application are of unique design and strong practicability.
