THE COMPRESSIVE STRENGTH AND ELASTIC MODULUS OF CONCRETE WITH A VERY LOW WATER/CEMENT RATIO /IN GERMAN/

THE PREPARATION OF CONCRETE WITH A VERY SMALL AMOUNT OF MIXING WATER (THE WATER/CEMENT RATIO BEING LOWER THAN 0.30) RESULTS IN VERY HIGH COMPRESSIVE STRENGTH IF COMPACTION IS COMPLETE. THIS TYPE OF CONCRETE IS PARTICULARLY SUITABLE FOR PRESTRESSING OR FOR CONCRETE CONSTRUCTIONS WHICH MUST FULFILL HIGH REQUIREMENTS. REPEATED VIBRATING TESTS WERE CARRIED OUT ON NINE CONCRETE MIXTURES WITH WATER/CEMENT RATIO VARYING FROM 0.24 TO 0.28. THE COMPRESSIVE STRENGTH OF THE CYLINDRICAL SAMPLES WAS HIGHER THAN 800 KG/CM SQUARED AFTER 28 DAYS, 1000 KG/CM SQUARED AFTER 3 MONTHS AND AT LEAST 1200 KG/CM SQUARED AFTER ONE YEAR. STEAM-CURING TREATMENT RESULTED IN A COMPRESSIVE STRENGTH HIGHER THAN 500 KG/CM SQUARED AFTER 24 HOURS. THE RELATION BETWEEN COMPRESSIVE STRENGTH AND ELASTIC MODULUS IS ALSO STUDIED. /LCPC/RRL/A/
