摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of dust and to reduce the rebound caused in spraying in the properties of shotcrete used for the covering work for a mountain tunnel or the like.
SOLUTION: In the shotcrete composed of a formulation containing at least cement, bentonite, fine aggregate and water as components, the ratio of bentonite to cement by mass is controlled to be ≤20 mass%, preferably 2-10 mass%. As a result, the effect of equal to or above degree of dust and rebound compared to the conventional formulation using silica fume is attained and the reduction of cost is expected.

摘要： PROBLEM TO BE SOLVED: To provide main column members of a steel pipe tower filled with concrete having a high workability at a low cost, and a construction method for steel pipe tower filled with concrete.
SOLUTION: Hollow steel pipes are connected together in up-down direction, and a connected body 3 of the hollow steel pipes is assembled. A filler 5 is placed under pressure at a low speed from a filler inlet 7 to near a bottom end portion of a preliminary mortar filler inlet 8 where the top of filled mortar is located. Placing of the filler 5 is interrupted, and a predetermined amount of preliminary mortar 6 first is poured above the top position of the filler 5 from the mortar filler inlet 8. A top hoper 16 is installed to the highest portion of the connected body 3 of the hollow steel piles, and the filler 5 is poured again under pressure until the top end portion reaches near an intermediate portion of the top hoper 16. Upon completion of pouring the filler 5 under pressure, surplus filler 5 remaining in the top hopper 16 is discarded when sedimentation is completed before the hardening of the filler 5, then the top hopper 16 is removed and the top surface of the connected body 3 of the hollow steel pipes is leveled.

解决方案：空心钢管沿上下方向连接在一起，组装中空钢管的连接体3。将填料5从填料入口7以低速压力放置在填充砂浆顶部所在的预备砂浆填料入口8的底端附近。填料5的放置被中断，并且首先将预定量的预备砂浆6从砂浆填料入口8注入到填料5的顶部位置之上。顶部搅拌器16安装到连接体3的最高部分中空的钢桩和填料5在压力下再次注入，直到顶端部分到达顶部浇料16的中间部分附近。在填充物5在压力下完成时，留在顶部料斗16中的剩余的填料5是在填料5硬化之前完成沉淀时丢弃，然后卸下顶部料斗16，并且中空钢管的连接体3的上表面平整。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide a cement-based hydraulic composition having high durability which can be applied as a mortar and a concrete member of a watertight or an airtight structure which requires preventing the development of a crack or suppressing a crack and a structure for shielding radiation etc. and in which the development of a crack resulting from temperature shrinkage, autogeneous shrinkage, and drying shrinkage is sufficiently suppressed.
SOLUTION: The hydraulic composition comprises a mixture of low-heat portland cement, fly ash, and an expansive composition. The content of the fly ash is 10-50% by mass. The expansive composition is obtained by mixing a clinker composition containing free quicklime and alite with gypsum, and the content of the expansive additive is 17-23 kg/m
