SUPERPLASTICIZED SILICA FUME HIGH-STRENGTH CONCRETES . ADMIXTURES FOR CONCRETE: IMPROVEMENT OF PROPERTIES. PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM HELD BY RILEM (THE INTERNATIONAL UNION OF TESTING AND RESEARCH LABORATORIES FOR MATERIALS AND STRUCTURES), BARCELONA, MAY 14-17, 1990

The effect of combined additions of silica fume and superplasticizer on concrete compressive strength has been studied by taking into account the following parameters: (a) type and dosage rate of superplasticizer; (b) type and content of Portland cement; (c) way of silica fume utilization (as additional component or as cement replacement). In the presence of silica fume, for both type I and type III Portland cement the Melamine Sulphonated Polymer superplasticizer performs better than the Naphtalene Sulphonated Polymer one, particularly when a high dosage such as 4% is used. A change from 2 to 4% superplasticizer dosage rate in general does not modify or reduce compressive strength in the absence of silica fume, whereas significantly increases compressive strength in the presence of silica fume.
