混凝土硬化 meaning in Chinese
concrete hardening
hardening of concrete
Examples
- On the course of hardening of concrete , the improvement of performance mainly lies in the decrease of plasticity cracks and interior cracks of concrete in quantity and in dimension and the enhancement of medium continuity
在混凝土硬化过程中纤维改善了混凝土的内部结构，主要表现在减少了混凝土的塑性裂纹和内部微裂纹的数量和尺寸，提高了混凝土材料介质的连续性，从而改善了混凝土的综合性能。 - Steel fiber reinforced concrete ( sfrc ) is a new compound civil engineering material . its properties have been studied deeply in recent years . comparing to the knowledge of the fully - hardening sfrc , we know very little about its properties in the early ages
但是，现在对钢纤维混凝土力学性能的研究大多集中在混凝土硬化完成之后的力学性能，而对于它在硬化发展过程中的各种力学性能的研究还不多。 - Specially , the axial tensile strength of the interface of the new and old concrete has reached above 2 . 40mpa , greatly surpassing the preconcert goal ( > 1 . 0mpa ) , and its flexural strength also above 5 . 80mpa , having surpassed the preconcert target and the standard request ( 4 . 50mpa ) . ( 2 ) after hardening 4h and 8h the compressive strength of the patched concrete is bigger than 20 mpa , which can satisfy the request of fast patching . ( 3 ) the ych color material , which is mixed into rapid sulfoaluminate cement - concrete patching material , can take better effect and avoid chromatism on the appearance of new - old concrete
特别是新老混凝土界面的轴向抗拉强度已达2 . 40mpa以上,大大超过原定目标(大于1 . 0mpa ) ,其界面抗折强度也在5 . 80mpa以上,也已超过原定指标及规范要求(大于或等于4 . 50mpa ) ; ( 2 )修补混凝土硬化后4h 、 8h抗压强度大于20mpa ,能满足快速修补的要求; ( 3 )在快硬硫铝酸盐水泥混凝土修补材料中掺入自配的ych调色材料,能较好地起到调色作用,避免新老混凝土表面色差。 - With the prerequisite of meeting requirement of its working performance , the mix design of common grades can be concluded though strength test if we check various property of the said concrete with the certain mix design , such as compressive strength , tensile strength , elastic modulus , reinforcement wrapping strength , leakage resistance , shrink property and charring resistance , and compare them with property of ordinary concrete , we will find that the various dynamic property of self - densifying high performance concrete is very satisfactory and the durability is quite ideal
在满足自密实高性能混凝土工作性能的前提下，通过强度试验得出常用强度等级混凝土的配合比，检测该配合比下的自密实高性能混凝土的抗压强度、劈裂抗拉强度、弹性模量、钢筋握裹力性能、抗渗性、收缩性、抗炭化性等性能，以及各种性能与普通混凝土的比较，验证自密实高性能混凝土硬化后的各方面力学性能是完全能够符合要求的，并且具有较高的耐久性。 - Parametric study indicates that steel thickness has small influence on the temperature field of cfst arch rib during construction , while diameter of tube has great influence . the thermal conductive coefficient of concrete has some influence on the temperature field ; but for the concrete with same aggregate , the coefficient varies in small range , so its influence is limited
应用通用程序对混凝土硬化过程中截面温度场的分析表明:钢管壁厚影响较小,而管径的影响较大;混凝土导热系数对截面温度场有一定的影响,但对于同一种骨料的混凝土,其影响不大。
