Material Modifications of High Performance Concrete Properties

Dear Colleagues,

Concrete is the basic building material used in construction. First of all, concrete is expected to maintain the required mechanical properties over the expected lifetime of the structure under specific environmental conditions, i.e., adequate strength and durability. High performance concrete is a concrete which possess high durability and high strength when compared to conventional concrete. As with other construction materials, the mechanical properties and durability of concrete depend on its structure. High performance concrete is obtained by improving structure due to the selection components of special properties and developing specific composition. It is essential that the structure and properties of concrete can be influenced by technological processes carried out at the construction site under varied and difficult-to-control conditions. The constantly increasing requirements for concrete structures, the increasing scope of their use, and ecological and economic requirements all result in the need to modify the properties of the fresh and/or hardened concrete. Material modifications are one way to address this. Effective material modification of concrete properties is not an easy task. It requires systematic data on the impact of material modifications on the properties of fresh concrete and hardened concrete in relation to its intended use, composition, properties of components, and conditions and technology of casting.

The purpose of this Special Issue is to present the latest concepts and research focused on developing the properties of fresh and hardened high performance concrete through material modifications. Of particular interest are articles focused on flexible modifications of concrete properties depending on the conditions of its casting and application, taking into account the implementation of sustainable development postulates.

For example, the research presented in this issue may cover the following topics: modification of the rheological properties of fresh concrete including self-compacting concrete, modification of the properties of fresh and hardened concrete for casting in special conditions (e.g., casting in summer or winter conditions, mass concrete casting), reduction of hazards resulting from thermal stress and shrinkage of concrete, improvement of concrete structure and its resistance to the corrosive effects of the environment, effects of mineral admixtures and additives, recycled materials, fiber-reinforced concrete, green concrete, etc.
