摘要
研究了硅灰掺量对硫铝酸盐水泥力学性能和电磁传输性能的影响.结果表明:随着硅灰掺量的增加,硫铝酸盐水泥的抗压强度和抗折强度均先增大后降低,硅灰的最优掺量为10%;硫铝酸盐水泥的电磁传输性能随着硅灰掺量的增加而增大,与未掺硅灰的样品相比,硅灰-硫铝酸盐水泥在3.94~5.99 GHz频段范围内电磁传输性能均有所提升,电磁透射率峰值最高提升了23.9%.
The effects of silica fume contents on the mechanical properties and electromagnetic transmission properties of sulphoaluminate cement were studied.The results show that with the increase of silica fume content,the compressive strength and flexural strength of sulphoaluminate cement increase first and then decrease,and the optimal content of silica fume is 10%.The electromagnetic transmission performance of sulphoaluminate cement increases with the increase of silica fume content.Compared with the sample without silica fume,the electromagnetic transmission property of silica fume-sulphoaluminate cement is improved in the range of 3.94-5.99 GHz.The peak value of electromagnetic transmittance is increased by 23.9%at most.
