项目摘要

In this study, the following was investigated in order to prepare the mix design method and the work method of the mortar for structures (the mortar, of which aggregate volume is increased by using fine aggregate with special grading to control drying shrinkage to the same level as that of concrete, for applying to structures).1. Segregation mechanism of aggregate: The process of segregation of aggregate subjected to vibrating compaction was visualized using the simulated mortar.2. Design method of grading of fine aggregate: The relationship between the grading of aggregate and the solid content was investigated. And the prediction method of the solid content of aggregate composed of two or three grain size was advanced.3. Effect of air content: The effect of air content of the mortar for structures on fresh properties was investigated. And it was determined that the yield value of the mortar is estimated comprehensively based on the distance between aggregates in dispersion calculated ignoring air content.4. Vibrating compaction method: The rheological properties and the segregation resistance of the mortar for structures subjected to vibrating compaction were investigated. And it was confirmed that the mortar for structures can be cast with the vibrating compaction method similar to that for concrete.5. Strength characteristics and drying shrinkage: The following results for the mortar for structures were obtained: 1) Compressive strength is nearly equal to that of concrete. 2) Young's modulus can be predicted by the JASS 5 equation. 3) Drying shrinkage can be controlled to the same level as that of concrete.6. Feasibility of high-fluidization: The feasibility of high-fluidization of the mortar for structures was investigated. And it was determined that if water cement ratio is less than 42.5%, the slump flow of the mortar for structures can be fluidized to 70cm.

在这项研究中，研究了以下研究，以准备混合设计方法和结构的迫击炮的工作方法（通过使用特殊分级的细分来控制与混凝土相同水平的结构的砂浆（砂浆）增加了骨料体积，以应用于结构。1。骨料的隔离机理：使用模拟迫击炮可视化骨料的隔离过程。2。细分等级的设计方法：调查了骨料的分级与固体含量的关系之间的关系。以及由两个或三个晶粒尺寸组成的聚集体的固体含量的预测方法。3。空气含量的影响：研究了砂浆的空气含量对结构对新鲜性能的影响。并确定砂浆的产量值是根据分散量计算中骨料之间的距离进行了全面估计的，忽略了空气含量4。振动压实方法：研究了对经受振动压实的结构的流变特性和隔离性。并且已经证实，结构的砂浆可以用类似于混凝土的振动压实方法施放。5。强度特性和干燥收缩：获得了结构的砂浆的以下结果：1）抗压强度几乎等于混凝土的抗压强度。 2）JASS 5方程式可以预测Young的模量。 3）干燥收缩可以控制到混凝土的水平相同的水平。6。高浮力化的可行性：研究了砂浆高氟化结构的可行性。并且确定水水泥比小于42.5％，结构的砂浆的倒塌流动可以流动至70厘米。
