Abstract: This paper studied the effect of triethanolamine (TEA) used as grinding aid on the physical properties of cement. The fluidity and fluidity loss of cement pastes mixed with polycarboxylate superplasticizer (PCE) were measured. And the grinding aid mechanism and the influence mechanism of TEA to the adaptability of cement and PCE were studied by testing the adsorption capacity of PCE, the temperature rise curves of cement hydration, the dissolution capacity of TEA and the surface property of cement particles. Results showed that with its dosage between 0%—0.02%, the addition of TEA could improve the particle size distribution of cement and thus the compatibility between cement and superplasticizer. While the adsorption capacity of PCE declined, the tempe-rature of cement hydration accelerated, and TEA showed obviously negative influence on the compatibility between cement and superplasticizer.
