concrete grade
Examples
- In kinematics similarity test , test simulates specimens in earthquake action . by the hysteretic curve , anti - seismic property of t - shaped and l - shaped short - leg shear wall can be realized
并且研究了在动荷载作用下混凝土等级、截面配筋率和墙肢截面高厚比等因素对短肢剪力墙抗震性能的影响。 - The research used materials are fast patching concrete 、 ordinary patching concrete and polymer mortar 。 the testing result indicates : ( 1 ) the mechanics properties of the patched concrete has surpassed the rank of c30 concrete
其研究使用材料有快速修补混凝土、普通修补混凝土及聚合物砂浆。试验结果表明: ( 1 )修补混凝土力学性能指标已超过c30混凝土等级的要求。 - The main contents are followed below : ( 1 ) for the aim of knowing the characteristics of main factory building structure frame columns of large - scale thermal power plants , nine high strength concrete frame columns with high axial compression ratio and six slender ordinary strength concrete frame columns with high axial compression ratio were tested under low reversed cyclic horizontal loading for the very first time , and thus the influencing factors of normal section bearing capacity , such as concrete intensity grade , axial compressive ratio , slendemess ratio , the type of stirrups and stirrup ratio , etc , the anti seismic deformation capability of frame columns were acquired
本文主要研究的内容有： ( 1 )首次针对火电厂主厂房结构框架柱的特点，对9个高轴压比高强混凝土框架柱和6个高轴压比普通混凝土框架长柱进行了低周反复水平加载试验，获得混凝土等级、轴压比、长细比、配箍形式及配筋率等对框架柱的抗弯及抗剪承载力、抗震变形能力的影响因素。 - In static test , t - shaped and l - shaped specimens were respectively divided into four groups according to concrete strength grades , sectional height to thickness ratio , reinforcement ratio and ratio of axial compressive force to axial compressive ultimate capacity of section . how these factors affect the load - carrying and deformation of short - leg shear wall is known by analysis the result
在拟静力试验中对t形和l形短肢剪力墙分别进行了四组试验，通过对试验结果的分析，揭示了混凝土等级、截面配筋率、轴压比和墙肢截面高厚比等因素对短肢剪力墙承载力和变形的影响。 - But it has limitations such as inconsistency between strength and theological properties , the problem of volume invariability and the properties of resistance of sulfate erosion especially for concrete in excess of 70mpa . it is an difficulty for both the concrete industry and building industry to ensure the concrete in excess of 70mpa with good theological behavior , ease of transport , volume soundness and durability after hardened
高强混凝土在促进整个建筑业的进步方面功不可没,但是随着应用的混凝土等级的提高,特别是对于70mpa以上的混凝土已暴露出自身的一些缺陷,如混凝土强度与流变性能之间的矛盾,体积稳定性问题,抗硫酸盐类侵蚀性能力的下降等。要使70mpa以上的混凝土具有良好的流变性能,能轻易地泵送,并在硬化后有良好的体积稳定性和耐久性,是国内外混凝土和建筑施工业面临的一项技术难题。
