卵石混凝土 meaning in Chinese
boulder concrete
Examples
- The experiment determined the fracture process and the parameter of the fracture properties of two different aggregate concrete and recorded the stable whole fracture curves of boulder concrete and crushed stone concrete separately , which are determined through three - point - bending method and wedge - split tensile method
测定了两种粗骨料混凝土的断裂过程及断裂特征参数，分别记录了两种试验方法测定的卵石混凝土和碎石混凝土的断裂全曲线。 - According to the recorded full process fracture curve , the paper calculated and compared the fracture toughness ( kic ) , the fracture energy ( gf ) and crack tip opening displacement ( ctod ) of the different strength grade boulder concrete and crushed stone concrete , it is found that the maximal load ( fmax ) and the fracture toughness ( kic ) of boulder concrete and crushed stone concrete increase when the strength of them increases , so does the fracture energy of boulder concrete , but the fracture energy of crushed stone concrete does n ' t obviously increase when it ' s strength increases . the crack tip opening displacement ( ctod ) of all specimens chang less when the strength of concrete increases , so it is concluded that the location of the axle in the ligament of the specimens is relatively stable
根据记录的全曲线，计算了不同强度等级的卵石混凝土、碎石混凝土的断裂韧度k _ ( ic ) 、断裂能g _ f以及裂缝的尖端开口位移ctod ，比较了不同强度等级卵石混凝土及碎石混凝土的断裂韧度k _ ( ic ) 、断裂能g _ f以及裂缝的尖端开口位移ctod的关系，发现卵石混凝土、碎石混凝土的荷载峰值fmax 、断裂韧度k _ ( ic )随强度增加而增加，卵石混凝土的断裂能g _ f随强度增加而呈增加趋势，碎石混凝土的断裂能g _ f随强度增加变化趋势平直，增势不明显。 - By using 5000kn pressure - bent testing machine , the specimens of boulder concrete and crushed stone concrete were tested through three - point - bending method and wedge - split tensile method , the scale division of the index dial of pressure - bent testing machine is larger , whereas the predicted test - load is lesser , so the velocity of exerted load is controlled through observing the reading of the multimeter which is connected with the collecting systerm in order to continuously exert test - load
本文使用5000kn压弯实验机，对不同强度等级的卵石混凝土和碎石混凝土试件分别进行了三点弯曲试验和楔入劈拉试验。试验过程中，由于实验机吨位较大，而试验荷载预计较小，为了能够有效地控制加载大小和加载速度，采用通过观察与荷载传感器相连的万用表读数控制加载速度的方法，连续加载。 - The results show that the compressive strength , splitting tensile strength and flexural strength increase respectively with the addition of steel fibers , but the compressive strength increases little compared with the splitting tensile strength and flexural strength ; for the same kind of steel fiber reinforced concrete , the compressive strength , splitting tensile strength and flexural strength of steel fiber reinforced regenerated concrete are higher than those of steel fiber reinforced pebble concrete ; the load - bearing capacity of blended steel fiber reinforced concrete is less than that of single dimension steel fiber reinforced concrete ; the use of steel fiber reinforced regenerated concrete whose aggregate is made of regenerated concrete can not only turn waste into treasure , but also reduce environmental pollution and realize the recycle of resources , and its load - bearing capacity is far higher than that of steel
结果显示:由于钢纤维的加入,混凝土的抗压强度、劈裂强度和弯曲强度都有不同程度的提高,但抗压强度不及劈裂强度和弯曲强度提高显著;对于同种钢纤维混凝土,钢纤维再生混凝土的抗压强度、劈裂强度和弯曲强度比钢纤维卵石混凝土的相应强度大;混杂尺寸钢纤维混凝土的承载能力不如单一尺寸钢纤维混凝土的承载能力;以再生混凝土作为基体的钢纤维再生混凝土不仅可以“变废为宝” ,减少环境污染,实现资源的重复利用,而且其承载能力比钢纤维卵石混凝土高很多。 3 .总结出钢纤维混凝土抗拉强度和弯拉强度关系的计算公式。
