Abstract	Electrical behavior of cement pastes with β-naphthalene sulfonate-formaldehyde condensate superplasticizer (FDN) and lignosulphonate superplasticizer (LS) as well as their relation to the fluidity of the pastes were investigated. The setting time tests of the pastes were also carried out. The resistivity at 5 min is regarded as initial resistivity. Results show that the FDN and the LS have different effects on the resistivity of cement pastes. The initial resistivity of the pastes changing with the amount of superplasticizer can be explained by the adsorption and the dissolution of superplasticizer. The curve of initial resistivity as a function of FDN dosage can be divided into 4 zones, which are the selective adsorption zone, the effective adsorption zone, the dissolution and ionization zone, and the saturated ionization zone, respectively. Each zone reflects the properties of FDN as a superplasticizer of cement paste. The LS dosage of the paste with the highest fluidity is the same as that of the highest initial resistivity. Electrical resistivity method will potentially be used to test the optimal dosage of LS.
