EXPERIMENTS WITH ADDITIVES FOR UNDERWATER CONCRETE /IN DUTCH/

RESEARCH WAS CONDUCTED INTO THE EFFICIENCY OF ADDITIVES IN PREVENTING THE WASHING OUT OF CEMENT UNDER WATER AND INTO THE STRENGTH ATTAINABLE. LABORATORY TESTS WERE CARRIED OUT ON CONCRETE MORTAR WITH AND WITHOUT ADDITIVES. EACH BATCH WAS USED FOR THE CASTING OF TWO TEST CUBES, ONE ABOVE AND THE OTHER BELOW WATER. THE TESTS WERE CONDUCTED IN FOUR STAGES, THE FAVORABLE RESULTS OF WHICH WERE AGAIN USED AS A BASIS FOR SUBSEQUENT TESTS. ALTHOUGH FAVORABLE RESULTS WERE OBTAINED WITH A NUMBER OF ADDITIVES, PREFERENCE IS GIVEN TO BENTONITE, SINCE IN ADDITION TO OTHER ADVANTAGES, THIS ADDITIVE IS RELATIVELY CHEAP. THE INFLUENCE OF BENTONITE WILL BE VERIFIED IN ACTUAL PRACTICE. /SWOV/RWL/RRL/
