Porous concrete cylinders 15/15 an were made mainly with coarse aggregate, which resulted in a porosity of the specimens of about 40 Vol. %.The specimens were cured according to German standards. After 28 days one half of the specimens was injected in the mould with a epoxide material and the rest with a cenenteous material. Reference specimens were not injected.The compressive strength of the reference specimens was determined prior to injection and the compressive strengths of the injected specimens were determined half an hour, two hours and 28 days after injection. Porosities were determined at the same time using both density measurements and Hg-Porosimetry.
