摘要：
The polymer-modified cementitious materials are widely used as functional building materials since the expanding of the application of polymer in construction industry. The dynamic mechanical properties of EVA polymer-modified cement pastes at early age were investigated by dynamic mechanical analysis at 0.49Hz-100Hz (loading frequency). Experimental results show that the dynamic flexural properties, as expressed by the storage modulus and loss tangent, ascended linearly with a logarithmic frequency. The storage modulus increased with the increase of the hydration time. On the contrary, the loss tangent of 3% and 5%P/C decreased according to increase of the hydration time at 7dyas.
