Abstract:Hydration curves of cements with varied superplasticizer were measured by isothermal calorimetry(TAM-AIR).Three heat release curves were analyzed by Db10.Cement hydration curve with new-type superplasticizer of polycarboxylic acid(SPC) lags behind that of cement adding naphthalene sulphonate formaldehyde(NSF) condensates and the control sample 171.3 min and 235.9 min respectively.Decomposition and reconstruction showed the approximation signal energy and the error of reconstruction signal and original signa...
