Study on the Performance of Water Reducing Agent in Jing-Shi Special Passenger Line
In this paper,in order to discuss the compatibility of cement and different kinds of water reducers,three kinds of water reducers which were selected to use in the mix proportion of Jing Shi Special Passenger Line were chosen.Tests of cement paste and concrete of Portland cement (P-O42.5) were carried out under different temperature,because this kind of cement is widely used in the current projects.Results show that polycarboxylic series water reducer,compared with naphthalene series water reducer,have properties of high compatibility,low mixing amount,high waterreducing rate and low slump loss of concrete.So it is more suitable to prepare concrete with fly ash and more beneficial to increase the strength of concrete.
