    • PROBLEM TO BE SOLVED: To provide a metallic fiber for reinforcing cement hardened body which is used for reinforcing a cement hardened body (particularly having high strength of ≥100 MPa compressive strength), can be easily and uniformly deipersed in a short period of time without being entangled with each other in kneading, has sufficient adhesiveness to a base material and can improve toughness and further mechanical strength such as bending strength of the cement hardened body.
      SOLUTION: As for the metallic fiber 1, its diameter is ≤0.3 mm, its tensile strength is 1.0-3.5 GPa and its shape is made spiral. The spiral shape is defined so that it has a cycle B >1.0 time and ≤5.0 times the fiber length and has an amplitude A 0.5-3.0 times the fiber diameter. The aspect ratio of the metallic fiber 1 is 20-200.

    • 要解决的问题:为了提供用于增强水泥硬化体(特别是具有≥100MPa抗压强度的高强度)的用于增强水泥硬化体的金属纤维,可以在短时间内容易地和均匀地脱落 的时间,而不会在捏合中彼此缠结,对基材具有足够的粘附性,并且可以改善水泥硬化体的韧性和进一步的机械强度,例如弯曲强度。

      解决方案:金属纤维1的直径≤0.3mm,拉伸强度为1.0-3.5GPa,形状为螺旋形。 螺旋形状被定义为使得其具有循环B> 1.0倍和纤维长度的≤5.0倍,并且具有纤维直径的0.5-3.0倍的振幅A。 金属纤维1的纵横比为20-200。 版权所有(C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To impart flexibility to concrete to prevent the concrete from fracturing caused by embrittlement due to the tensile stress in concrete.
      SOLUTION: Starlet dodecahedron shape aggregate 1, provided with a non-adhesive surface repelling concrete from the surface, is mixed with cement at a prescribed ratio. The aggregate 1 acquires the non-adhesive surface by forming the aggregate 1 with a material having no adhesivity to concrete, or by having a film 7 on the surface of the aggregate 1, provided that the filling factor of the aggregate 1 is made 50% or more relative to the closest packing state that means mixable maximum amount of aggregate.

    • 要解决的问题:为了赋予混凝土灵活性,以防止混凝土由于混凝土中的拉伸应力而引起的脆化引起的压裂。

      解决方案:从表面设置有非粘性表面排斥混凝土的Starlet十二面体形状骨料1以规定的比例与水泥混合。 聚集体1通过用不与混凝土粘合的材料形成骨料1,或者通过在骨料1的表面上具有膜7来形成非粘性表面,只要骨料1的填充系数为50% 或更多相对于最接近的包装状态,这意味着可混合的最大量的聚集体。 版权所有(C)2007,JPO&INPIT
