Mirja Illikainen, in New Materials in Civil Engineering, 2020 15.1 Introduction It will demonstrate that these materials can be successfully produced to exacting standards by the application of standard concrete technology principles. Guidance is also given for specifying these materials. ![]() This chapter discusses the selection of aggregates, concrete mix design and production requirements together with a summary of the properties of high-density concrete and grouts. In addition, the properties of both fresh and hardened products can be different from those of normal concrete and therefore require careful evaluation before use. This offers the concrete technologist additional challenges when using these for producing concrete or grout. This restricted use has meant that both the availability and properties of aggregates can be fundamentally different from conventional materials. There has, however, been increased use within the UK in non-nuclear applications. ![]() Consequently the development of these materials has been limited to two periods, the early nuclear power programme, in the USA, during the 1950s and 1960s, and in the UK to a considerable extent during the 1980s and 1990s. High-density, or heavy density, concrete accounts for a relatively small section of concrete production within the construction industry with specialist applications traditionally within the nuclear industry.
