Definitions
- the present invention relates to a cementlessly promoted admixture, and more particularly, to a promoted admixture for use in the manufacture of cement using a calcium-based stimulant and a cementite composition comprising the same.
- Carbon dioxide (CO 2 ) is a type of greenhouse gas and one of the major causes of global warming. In Korea, 80% of CO2 is emitted from the energy industry, 24% of which is emitted from buildings, and in general, rebar and cement generate the most carbon dioxide among building materials. Therefore, various researches are being conducted to develop eco-friendly building materials, especially eco-friendly concrete, which can reduce carbon dioxide emissions as much as possible while saving energy.
- Concrete is mixed with water by putting aggregates such as sand, gravel, and reinforcement into cement powder and mixing it with water to obtain the desired structure.
- Calcium oxide (CaO) which is the main component of cement, is obtained by heating calcium carbonate (CaCO 3 ) at a high temperature of 1600 ° C. In this process, a large amount of carbon dioxide is generated by about 5 of the carbon dioxide produced and released by humans during industrial activities. It is pointed out that it is a serious problem.
- Eco-friendly concrete is produced using environmentally friendly raw materials to reduce environmental pollutants. It is characterized by lower energy consumption and carbon dioxide emissions than general concrete.
- fly ash and granulated blast furnace slag are widely used as cement binders, and much research has been conducted as raw materials for cement.
- strong alkaline stimulants such as potassium hydroxide (KOH) and sodium hydroxide (NaOH) are mainly used to prepare the hydrous or hardened body of cement.
- the strong alkaline stimulant is a Na + ions or K + ions are directly involved in the hydration phase of the cured body to produce a cemented hardened body, the reaction occurs rapidly due to the strong alkalinity, there is a problem in workability and the raw material cost is difficult to commercialize There is this.
- a strong alkaline stimulant there is a disadvantage that it is impossible to use a water sensitizer (chemical admixture for concrete) and the like because the pH increases rapidly and the reaction occurs rapidly.
- Circulating Fluidized Bed Combustion Ach (hereinafter referred to as CFBC ash) is an ash produced in a circulating fluidized bed combustion boiler (CFBC boiler). Since circulating fluidized bed boilers are circulating, CFBC ash is produced at 850-900 ° C, which is very low compared to 1200-1400 ° C, which is the production temperature of a typical Pulverized Combustion (ASH) boiler ash. At this temperature, the ash particles do not melt, so the surface area of CFBC ash is indefinite, unlike ordinary PC boiler ash (refining ash), which has a reduced surface area during melting and cooling at high temperatures. In addition, unlike the refinery ash does not contain amorphous because it occurs at a temperature lower than the hot melt temperature.
- CFBC boiler circulating fluidized bed combustion boiler
- a circulating fluidized bed boiler may use limestone for the fluidized bed in order to increase the removal efficiency of sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) during combustion.
- SO 2 sulfur dioxide
- NO x nitrogen oxides
- the fluidized bed is made of limestone
- CaSO 4 calcium sulfate

- Al 2 O 3 aluminum oxide
- SiO 2 silicon dioxide
- the reaction of CaO + H 2 O-> Ca (OH) 2 produces calcium hydroxide, which acts as a stimulator of the blast furnace slag.
- the resulting calcium hydroxide reacts with the blast furnace slag to form a dense hydrated phase (hard phase) of the CSH hydrated phase (CaO—SiO 2 —H 2 O) system, thereby giving strength to the blast furnace slag based cement.
- Calcium hydroxide is a weak alkaline stimulant which is very favorable for the initial and long-term compressive strength development, and it is very effective in controlling the initial fluidity of the cement and the loss of fluidity over time because it is very stable with the chain slag.
- the calcium oxide component of the CFBC ash is produced and active at high temperatures and thus exhibits higher intensity than the quicklime component on the market.
- Fly ash is not as hard as blast furnace slag but is hydrated and cured when there is a stimulant such as calcium hydroxide. Fly ash is relatively less amorphous (glassy component) than blast furnace slag, but very stable reaction with calcium hydroxide stimulant, it is advantageous for long-term strength development rather than initial strength.

- Fly ash used refinery ash generated from Boryeong thermal power plant, and the specific surface area was 3400cm2 / g.
- CFBC ash used as a stimulant was used by grinding with a vibration mill so that the specific surface area was 5000 cm ⁇ 2> / g.
- the components of each raw material were measured using XRF (X-ray Fluorescence Spectroscopy), and the results are shown in Table 1 below.
- each particle shape was observed using an electron microscope (SEM), and the results are shown in FIGS. 1A to 1C.
- Figure 1a is a blast furnace slag
- Figure 1b is a fly ash
- Figure 1c is an electron micrograph showing a CFBC ash.
- triol compound TEA and glycerin were used, and both compounds were used in a liquid form having a solid content of 85%.
- a predetermined blending water and a chemical chemical admixture for concrete were added and mixed in a mortar mixer.
- the mixed paste was used to measure physical properties and molded molding.
- the mixture was allowed to stand at room temperature (20 ° C.) for 2 hours and then cured at 60 ° C. for 24 hours to measure strength and physical properties.
- a cubic mold of 5 ⁇ 5 ⁇ 5 cm 3 was used, and after curing at 60 ° C., the mold was demoulded and the compressive strength was measured using a compressive strength machine.
- Example 1 using TEA based on 28 days after curing showed a compressive strength of 145% compared to Comparative Example 1 of the reference formulation
- Example 2 using glycerin 194 The intensity expression rate of% is shown.
- both Example 1 and Example 2 showed an initial strength improvement of 139% or more compared to Comparative Example 1, which is the reference formulation, under the conditions of daily accelerated curing.
- AD1 is a carboxylic acid-based high performance reducing agent for concrete, and 20% of solid solution was used.
- Example 3 The strength of the cured body after curing was compared for Comparative Example 2, in which only the reducing agent AD1 was added without adding an accelerated admixture, Example 3, in which the reducing agent AD1 and glycerin were added, and Example 4, in which the reducing agent AD1, glycerin, and TEA were added. .
- Table 3 The results of comparing the compounding ratio and the compressive strength are shown in Table 3 below.
- Examples 3 and 4 both showed a high intensity expression rate of 131% or more at 1 and 28 days compressive strength compared to Comparative Example 2 which is the reference formulation.
- Example 3 was compared to Comparative Example 2, which is a standard formulation. It can be seen that the amount of etringite and calcium hydroxide is reduced in comparison. It is thought that this is because the activity of the blast furnace slag was promoted by the triol group at the end of glycerin, and the decrease in calcium hydroxide was particularly attributed to the exhaustion of calcium hydroxide on the CSH due to the acceleration of hydration of the blast furnace slag.
- Example 3 As can be seen in the electron micrograph of FIG. 3, the small and fine hydration phase of CSH was well developed in Example 3, in which 0.6% of glycerine was added, compared to Comparative Example 2, in which glycerine was not added. It is interpreted as the cause of the increase in the compressive strength.
- AD1 is a carboxylic acid-based high performance reducing agent for concrete, and 20% of solid solution was used.
- Table 4 The results of comparing the mixing ratio and the compressive strength are shown in Table 4 below, and the compressive strength according to the content of the triol compound is shown in FIG. 4.
- Comparative Example 3 is the standard formulation when glycerin and TEA were added, and compared to Comparative Example 3, the standard formulation from 1 to 28 days of curing. It exhibited an intensity of at least%. At 0.9% of the amount used, the initial strength was higher than 160% (1 day curing day), and the intensity was over 150% even for 28 days curing. This seems to be due to the fact that the compound containing the terminal triol had a sufficient function as a curing accelerator for both the blast chain slag and the fly ash.
