| titleOfInvention | Manufacture method of high strength composition for manufacturing concrete pile |
| abstract | The present invention relates to a method for manufacturing a high strength concrete pile file, and more particularly, to a method for producing a high strength concrete pile file, comprising the steps of: preparing 30 to 70% by weight of Portland cement, 20 to 60% by weight of slag powder, 3 to 12% by weight of anhydrous gypsum and 1 to 5% The mixture was mixed with water, mixed cement, sand, gravel and a fluidizing agent to prepare a composition. After 3 days from the preparation of the concrete pile with the composition, a compressive strength of 800 kg / In order to prepare the concrete pile that, compositions per 1m 3, water 100 ~ 160kg / m 3, the cement mixture 410 ~ 600kg / m 3, the sand 650 ~ 850kg / m 3, gravel 1,100 ~ 1,500kg / m 3 and flow agents 6 To 11 kg / m < 3 & gt ;. According to the present invention, since Portland cement, slag powder, anhydrous gypsum and gypsum are blended beforehand to disperse the fine powder uniformly, it is possible not only to stably produce a concrete file of high strength, but also to improve quality such as stability, water tightness and durability, Can be reduced. |
