They conclude that the compressive strength of UHPC is dependent on silica fume content since the additional amount of silica fume decreases the water demand which, in turn, needs more superplasticizer to make the concrete mix workable. Effective superplasticizers for UHPC are based on polycarboxylate ethers (PCE).
