Concrete has come a long way since the invention of Portland cement at the end of the 19th century. The material was constantly improved, leading to the development of high and ultra-performance concrete, which opened new opportunities for architects and designers.
The performance of concrete can be determined in terms of mechanical properties or durability. High-strength concrete was first introduced in the 1990s. Its development was largely due to the appearance of silica fume, leading to compressive strength values exceeding 100 MPa and durability improved to levels not previously known. Countless structures around the world including bridges, high-rise buildings and oil platforms were built using this type of concrete. High strength was often the key parameter but in many cases, it was the improved durability that was decisive. Concrete with a compressive strength well exceeding 200 MPa, so-called ultra-high performance concrete, were the next step of the evolution process, as the density and homogeneity of the binder matrix had been further improved, resulting in even better durability, potentially elongating the life span of concrete structures far beyond 100 years.
This success stories have one drawback. Typically, high and ultra-high performance concrete contain large amounts of Portland cement leading to a substantial CO2 footprint. Worldwide research is trying to tackle this huge environmental problem. One of the recent trends is to increase the usage of alternative cementitious binders. Unfortunately, these novel ecological systems often have unknown durability and long-term performance. To close this knowledge gap, this Special Issue will deal with research leading to improved high and ultra-high performance concrete with the clear aim of sustainable construction.
It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are all welcome.

The paper focuses on the experimental determination of shrinkage process in Ultra High Performance Concrete (UHPC). Special moulds with one movable head are used for the measurement. The early-shrinkage (48 hours) is continuously measured using an inductive sensor leant against the movable head, and a strain gauge embedded inside the test specimen. To monitor the long term shrinkage, the specimens are also equipped with special markers, embedded into the specimens’ surface. These markers serve as the measurement bases for the mechanical strain gauge. The test specimens are demoulded after 48 hours and the long term shrinkage is monitored using the embedded strain gauge (inside the specimens) and mechanical strain gauge placed, in regular intervals, in the markers on the specimens’ surface. Two sets of test specimens are manufactured for the experiment. One set is left to dry freely during the whole time of measurement in the laboratory with a temperature of 22 ± 2°C and relative humidity of 55 ± 10 % (including the early stage of solidification process). The second one is cured under autogenous conditions during the whole time of measurement
