摘要：

To determine the reaction degrees of Portland cement and fly ash in complex pastes, an experiment of hydration degree for composite pastes, hydrochloric acid dissolution method for fly ash and solution heat method for cement is applied. It is shown from the test that a rather precise result has been obtained by the combined method. The hydration degrees of cement and fly ash in composite pastes agree well with those from theoretical analysis.
