Reactive powder concrete (RPC) is a special type of with microstructure optimised by precise gradation all particles in the mix to yield maximum density. Therefore, RPC exhibits ultrahigh strength and durability. High-strength reinforcement has both high good plastic deformation properties, so combination high-strength can fully exploit their respective advantages. At present, there little rese...

Objective: To provide examples of the installation stainless-steel reinforcements in a stone cultural monument as part conservation and restoration work. Methods: During works, metal elements monuments are replaced by stainless steel, which shares same physical properties as, for example, iron, but its chemical much superior. Estimates appropriate reinforcement, technical drawings detailed plan...

Introduction The nondestructive, in-situ testing of early-age concrete properties is a crucial point for the progress of many construction projects in the building sector. The application of such techniques can establish e.g. the earliest possible form removal from concrete construction elements, thereby opening highways to traffic or releasing prestress from steel reinforcement with greatest e...
