矿渣微粉-粉煤灰-高效减水剂与水泥净浆的流动度
With the increase in the content of round and curved sand in the substituted ISO standard sand, the water demand decreases and thus the flowability and workability im-proves, while the strength tends to drop down.
随着代用ISO标准砂中圆球状曲面体含量的增多,胶砂用水量减小,流动度增大,和易性变好,但强度却呈下降趋势。
The dispersion effects of hyperdispersants on carbon black were studied withflowability,viscosity and area of thixotropic hysteresis loop as quantitative parameters.
以流动度、粘度、触变环面积为定量指标，研究了超分散剂对炭黑的分散性。
Study on effect of water-cement ratio and slag addition on cement motar strength and degree of fluidity;
水胶比、矿渣掺量对水泥砂浆强度及流动度影响的研究
The results indicated that in the three water-reducing agents, the hydrate system which contained KH-JS had the biggest degree of fluidity, but its early degree of fluidity was small,next was the FDN,and its .
结果表明,掺KH-JS减水剂石膏水化体系的流动度最大,但初始流动度较小;掺FDN的流动度次之,初始流动度最大;掺MG的流动度最小。
In addition,the influence of replacement of fly ash in the doublemixture cement mortar on the strength,flow degree and dry shri.
研究了水胶比、粉煤灰掺量、硅灰掺量、粉煤灰与硅灰双掺对水泥净浆性能的影响,结果表明粉煤灰、硅灰双掺可克服单掺粉煤灰早期强度低的缺点,又可保证后期强度增长较快;还分析研究了双掺水泥胶砂中粉煤灰掺量对强度、流动度、干缩等性能的影响,当硅灰掺量5%,粉煤灰掺量为30%～40%时,其抗压、抗折、干缩性能均优于流动性接近的基准胶砂。
