Trade Journals for the Concrete Industry

For precise testing of the compressive strength of high-strength concretes, high-performance concretes and stone and rock specimens, plane-parallel grinding surfaces are an extremely important prerequisite. EN 12390-3 and EN 12504-1 set out the requirements for test specimens in terms of evenness; and for grinding end surfaces the requirements of EN 12390-1 must be met. Based in Riedlingen in Germany, Form + Test Prüfsysteme has developed the new, ergonomically designed and easy-to-use PSM 3 specimen grinding machine to prepare core and cylinder test specimens.
