road concrete meaning in English
铺路混凝土
Examples
- Specifications for constructions and acceptance of road concrete pavement
水泥混凝土路面施工及验收规范 - The problem to cause crack of road concrete pavement early in guangxi province and prevention method
广西公路路面早期裂缝的原因及其防治 - Based on the theory of shrinkage , capillary force theory , the influence of road concrete additives in common use on surface tension of water is studied , and the results show that the influence of water reducer is very small whereas shrinkage - reducing agent and air entrainer can reduce surface tension of solution significantly . the relation between surface tension and additive dosage are non - linear relation . each additive has an obvious critical micelle concentration ( cmc )
从混凝土收缩的基本理论? ?毛细管张力理论出发,通过道路混凝土外加剂对水的表面张力的影响研究发现,减水剂对水的表面张力的影响很小,而减缩剂和引气剂可以大幅度降低溶液的表面张力,溶液的表面张力随外加剂的掺量呈非线性形式降低,而且都存在临界胶束浓度。 - The essay researched the compressive strength , bending strength , impact resistance and abrasion resistance of high strength polypropylene fibermesh concrete the mechanism of enhancing the properties of high strengh poloypropylence fibemesh road concrete composite was discussed and analyzed the regression on tensile strengh with portland cement mixed with fiber was derived using experiment the tensile strength of fiber soil stablization with porland cement was increased with dosage and length of fiber while the former was more effective than the latter test and analysis results indicate that polypropylene fiber can not only reinforce the strength of concrete , but also obviously promote the flexural fatigue life by the great stress the application of polypropylence fiber reinforced concrete in pavement construcion are also introduced
文章研究了不同掺量有机纤维混凝土的抗压、抗折强度、抗冲及性能、疲劳性能及耐磨性等各种路用性能，综合论述了有机纤维对水泥混凝土路用性能的影响。通过试验阐述了纤维水泥混凝土各种路用性能与纤维掺量、长度间的关系。分析表明纤维水泥混凝土随着纤维掺量和长度增加而增加，且纤维掺量对纤维混凝土抗拉强度的影响比纤维长度的影响更大。
