In this paper, piezoceramic bender elements technology is first used to test the dynamic shear modulus of polymer grouting materials. The test procedure is designed and the related mould is manufactured. The problems of influencing the precise measuring the transmitting time of shear wave are solved including system delay, excitation signal, frequency and the method of determining the transmitting time. Based on it, the influence on polymer dynamic shear modulus of density and excitationdoi:10.17559/tv-20160205080600 fatcat:xnlbc6e3vzcn3jo2anoyiuvlwq
