EFFECT OF MIXING TIME ON UNIFORMITY OF MIXTURE PROPERTIES IN MIXERS FOR ROAD CONCRETE

EINFLUSS DER MISCHDAUER AUF DIE GLEICHMAESSIGKEIT DER MISCHGUTEIGENSCHAFTEN BEI BETONMISCHERN FUER STRASSENBETON

TO ESTABLISH CRITERIA FOR EVALUATING THE EFFECTS OF MIXING, COMPREHENSIVE DATA ARE TO BE OBTAINED IN A COMPARATIVE STUDY OF MIXTURES USED IN CONCRETE ROAD CONSTRUCTION. THE PROCESSES INVOLVED IN THE MIXING OF CONCRETE IN ASSOCIATION WITH CEMENT FORMATION AND HYDRATION IN THE INITIAL PHASE REQUIRE THOROUGH RESEARCH. THERE HAS ALSO BEEN NO SATISFACTORY THEORETICAL STUDY OF THE MIXING PROCEDURE, PARTICULARLY OF THE MIXING TIME REQUIRED.
