  • the present invention is characterized by shortening the strength increase and the high temperature curing period by using a combination of blast furnace slag and bottom ash to complement the low strength and long-term high temperature curing period which is a disadvantage of the bottom ash.
  • the polymerization reaction is a Si-Al-containing mineral reacts with NaOH or KOH
  • the bottom ash is a binder that can be activated by polymerization because the content of SiO 2 and Al 2 O 3 is relatively high.
  • a glassy film is formed, so that an alkaline environment, a high temperature curing method or other method having a pH of 13 or more is required in order to break the film and promote the reaction of the bottom ash.
  • most of the high temperature curing caused the glass film of the bottom ash to be destroyed to induce a polymerization reaction.
  • the constituent components of the blast furnace slag contain SiO 2 , Al 2 O 3 , especially CaO (generally 40% or more of the blast furnace slag)
  • the hydration reaction and polymerization reaction are performed at room temperature. It is analyzed that even if a large amount of bottom ash is mixed due to the formation of a strong alkaline substance such as OH) 2 and a large amount of bottom ash is mixed, a polymerization reaction occurs at room temperature and the strength is greatly expressed.
  • the blast furnace slag is characterized in that 5 to 45% by weight of the total powder of the binder. More preferably the blast furnace slag is 25 to 35% by weight of the total powder of the binder is reasonable.
  • the reason for this limitation is that if the blast furnace slag is less than 5% by weight of the total amount of the binder, the workability is secured, but the compressive strength is considerably lowered due to room temperature curing, and the blast furnace slag is 45% by weight of the total amount of the binder. If it exceeds the compressive strength can be secured with high strength, but because the workability is not secured.

There is a problem that can be.
  • the powder which is not pulverized is less than 2,000 cm 2 / g, and shows a relatively low strength even less than 10 MPa even at 28 days. This is because when a non-crushed bottom ash (powder less than 2,000 cm 2 / g) is used, a glassy film is present in the bottom ash, which inhibits the polymerization reaction. And the powder also 5,000cm case of using the 2 / g up to the early strength and long term strength is increased by one, also powder 6,200cm 2 / g is more, the strength is reduced. In terms of strength, the bottom ash powder is preferably 4,000 to 5,000 cm 2 / g.

  • the reason for limiting the powder amount of the binder is that Si and Al and Na in an appropriate ratio required for the polymerization reaction must be present. If the weight ratio of the binder is larger than this, the Na necessary for the reaction is relatively insufficient and the strength is lowered. On the contrary, when it is smaller than this, the strength is lowered due to the lack of Si or Al contributing to the strength.
  • the sodium silicate is preferably used having a molar ratio of SiO 2 and Na 2 O has a value in the range of 1.0 to 3.4, when the molar ratio is less than 1.0, the viscosity of the binder is sharply increased and the slump is lowered to reduce the workability On the contrary, when the Si component required for the polymerization reaction decreases, the long-term strength decreases, and when the molar ratio exceeds 3.4, it does not affect the workability, but there is a problem that the initial strength decreases due to the decrease of Na ions.

  • the calcium carbide (CaC 2 ) is a by-product generated during the production of acetylene (C 2 H 2 ) gas, and shows the process of forming calcium hydroxide (Ca (OH) 2 ) by the reaction of water with calcium carbide.
  • the calcium hydroxide thus formed meets the components of Si, Al, and Fe of bottom ash, causing a pozzolanic reaction in the form of CSH gel, which is similar to CSH obtained in the hydration reaction, which allows strength to be expressed in mortar or concrete. Will be.
