摘要
水灰比、砂灰比、砂率、粗骨料形状和最大粒径、空气含量、外加剂等是新拌滑模混凝土抗剪强度变化的内因，温度、时间和变形速度是其变化的外因。本文通过大量的试验研究，探讨了上述因素对用于水平滑模施工的低流动性新拌混凝土的抗剪强度的影响规律。
The internal causes of influencing the shear strength of fresh concrte are the water-cement ratio, sand-cement ratio, sand percentage, coarse aggregate shape and maximum diameter, air content, and additives, and the external causes are the temperature time, and deformation speed. By great deal of experimental study, explore the influencing laws of the above factors on shear strength of low fludity concrete used in slip-form paving.
