Abstract:
Concrete and reinforced concrete are the most commonly used and most reliable construction materials today. Concrete producers states that, under optimal conditions, their products have an infinite lifespan. However, various weather phenomena (eg rain, frost or chemicals from the air), in combination with poor quality of concrete and structural damage over time can cause severe damage to the concrete structure. The current conditions on the performance demands on the durability of construction, their quality, minimizing risk during the operation, including in extreme conditions requires the development and use of new materials. Priority action is moving particularly on ensuring construction to withstand an earthquake.
