Abstract:
A deflocculation test based on the method proposed by Vehhasselt and Pairon has been applied to different mixes of cement admixtures to distinguish quickly between plasticizer and superplasticizer. The admixtures used were commercial products containing different proportions of lingnosulfonates (L), sulfonated naphthalene formaldehyde condensate (SNF), and sulfonated melamine formaldehyde condensate (SMF). Three different cements were employed: a low tricalcium aluminate (C3A = 2.5 percent); a high-alkali content (Na2O equivalent = 0.95 percent); and a high-fineness portland cement (S. A. Blaine = 500 m2/kg). In addition, the minimum active dosage of superplasticizer was calculated. The influence of the type of cement on the minimum active dosage is clearly shown by the results obtained through this method.
