ABSTRACT
Abstract This paper deals with the special properties of dry concrete, particularly its workability. The exceptionally low workability of dry concrete might be a disadvantage, but it can as well create new opportunities for products, such as hollow-core slabs and concrete pipes. General requirements for testing methods are also presented. Four of them are discussed in more detail: Modified VB-test, Proctor test, Kango-Hammer test and Intensive Compaction test. Keywords: Dry Concrete, Precasting, Workability, Testing Methods, Hollow-Core Slabs.
