EXPERIENCES WITH PATCH MORTARS FOR CONCRETE ROADS AND INVESTIGATIONS ON THE AIR CONTENT OF ROAD CONCRETE /IN GERMAN/

THE MONOGRAPH CONTAINS REPORTS ON MINISTERIAL RESEARCH CONTRACTS CARRIED OUT BY THE OTTO-GRAF-INSTITUT. PART 1 DEALS WITH TESTS AND EXPERIENCES WITH CEMENT-CONTAINING PATCHING MORTARS FOR CONCRETE SURFACES. THESE TESTS WERE STARTED IN 1959. PART 2 DISCUSSES CORRESPONDING TESTS CARRIED OUT IN 1961 AND 1963 ON PLASTIC PATCHING MORTARS, AND REFERENCE IS MADE TO LATER TESTS STARTED IN 1967. PART 3 DESCRIBES TESTS TO DETERMINE THE INFLUENCE OF CONCRETE MOISTURE CONTENT, TYPE OF AGGREGATE AND MIXING TIME ON THE AIR CONTENT OF RIGID ROAD CONCRETE. IT WAS ESTABLISHED THAT A CORRECT CHOICE OF AIR-ENTRAINING AGENTS ALLOWS THE OPTIMUM 4% AIR CONTENT OF FRESH CONCRETE TO BE ATTAINED. /FG/RRL/
