The present invention relates to a high powder slag cement production method for producing a high powder slag cement using the slag by-produced in the production of pig iron in steel mills.
슬래그는 선철의 제조시 발생되는 부산물로서 전체 철강생산량의 35% 정도로 많은 양이 발생되고 있다. 슬래그는 잠재수경성 물질이며, 이를 시멘트 혼화재료로 사용할 경우 수산화칼슘이나 황산염의 자극장용에 의해 수화열에 의한 온도상승 억제, 알칼리 실리카반응의 억제, 황산염 및 해수에 대한 화학저항성, 염화물 이온이나 산소 침투 저항성이 향상되는 장점들 있는 것으로 알려져 있다. 또한 이와 같은 슬래그 미분말을 보통 포틀랜드 시멘트와 혼합사용할 경우 콘크리트의 다양한 성능향상과 더불어 환경적 측면에서의 천연자원 고갈방지, 시멘트 생산시 발생되는 CO2 배출량 감소 등의 환경부하 저감 효과가 있다. 하지만 이러한 장점들에도 불구하고 슬래그 미분말을 혼입한 콘크리트는 보통 포틀랜드 시멘트를 사용한 경우에 비하여 조기강도의 저감, 양생시 온도조건에 따라 강도발현 성능이 저하될 수 있는 온도의존성이 크다는 문제점을 내포하고 있다.

In addition, when the slag fine powder is mixed with ordinary portland cement, it can improve the performance of concrete and reduce the environmental load such as preventing the depletion of natural resources in the environmental aspect and reducing the CO 2 emission generated during cement production. In spite of these advantages, however, concrete containing slag fine powder has a problem that the temperature dependence of the early strength reduction and the strength expression performance may be lowered depending on the temperature condition during curing, compared to the case of using ordinary Portland cement. .

이하 본 발명의 바람직한 실시 예를 첨부된 도면의 참조와 함께 상세히 설명하면 더욱 명백해 질것이다.
DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be more clearly described with reference to the accompanying drawings.
먼저, 슬래그분말에 무수석고를 투입하여 믹싱하여 균등분산시키는 제 1혼화단계을 실시하고, 상기 제 1혼화단계를 통해 생성된 혼합물에 포틀랜드 시멘트를 투입하여 믹싱하는 제 2혼화단계를 거친 후 상기 제 2혼화단계를 통해 생성된 혼합물에 표면개질제를 투입 한 후 이들 혼합물을 4000~8000cm2/g의 분말도를 갖도록 동시에 분쇄하는 분쇄단계를 거쳐 고분말도 슬래그 시멘트를 제조한다.First, a first mixing step of mixing and uniformly dispersing by adding anhydrous gypsum to the slag powder, and after the second mixing step of mixing by mixing the portland cement to the mixture produced through the first mixing step, the second mixing step After the surface modifier is added to the mixture produced through the mixing step, these mixtures are pulverized at the same time to pulverize the mixture to have a powder degree of 4000 ~ 8000cm 2 / g to prepare a high powder slag cement.
여기서, 상기 제 2혼화단계를 통해 생성된 혼합물과 표면개질제를 종래 시멘트의 혼합 방식과 동일하게 혼합하게 되면 초기강도가 낮아질 수도 있으므로, 본 발명에서는 진동밀을 이용하는 혼합-분쇄 방식을 통하여 저발열의 특성을 유지하고 초기강도를 확보하였다.
Here, since the initial strength may be lowered when the mixture and the surface modifier generated through the second admixing step are mixed in the same way as the conventional cement mixing method, in the present invention, low heat generation is achieved through the mixing-crushing method using a vibration mill. Maintained characteristics and secured initial strength.
상기 진동밀은 편심을 가진 원에 의해 밀 전체가 진동을 하면서 밀 안의 볼이나 바와 같은 분쇄매체가 분쇄물에 충격력과 마찰력을 동시에 전달하여 분쇄물을 미크론 단위까지 분쇄하여 분체의 구형화를 통한 비표면적의 증가와 표면 마찰 및 긁힘에 따른 표면결합을 유도시켜 분쇄대상물의 반응성을 증가시킨다.
The vibratory mill vibrates the whole mill by a circle with an eccentricity, and the grinding media such as balls or bars in the mill simultaneously transmit the impact force and the frictional force to the mill, thereby grinding the mill to the micron unit, thereby reducing the spherical weight of the mill. Increasing the surface area and surface bonding caused by surface friction and scratches to increase the reactivity of the grinding object.
계속해서, 무수석고는 슬래그 분말의 수경성을 유발시키기 위한 것이며, 또한 강도를 높여주는 작용을 한다. 상기 무수석고는 슬래그 분말 100중량부에 대하여 2 ~ 20중량부가 투입된다. 만약 무수석고가 2중량부 미만이 되면 슬래그 분말의 수경성을 유발하는 자극성분의 부족으로 수화능이 부족하게되며, 20중량부를 초과하게되면 첨가량에 비해 수경성을 유발하는 자극효과가 낮아 효과적이지 못하다.
Subsequently, anhydrous gypsum is intended to induce the hydraulic properties of the slag powder, and also serves to increase the strength. The anhydrous gypsum is 2 to 20 parts by weight based on 100 parts by weight of slag powder. If anhydrous gypsum is less than 2 parts by weight, the hydration ability is insufficient due to the lack of a stimulating ingredient that causes the hydraulic properties of the slag powder, and if it exceeds 20 parts by weight, the irritation effect causing the hydraulic properties compared to the added amount is not effective.
상기 포틀랜드 시멘트는 슬래그 분말의 수경성을 더욱 증가시키기 위해 첨가되는 것으로 상기 제 1혼화단계를 통해 생성된 혼합물 100중량부에 대하여 100 ~ 200중량부가 투입된다. 이러한 포틀랜드 시멘트는 100중량부 미만이 되면 상기 무수석고와 동일하게 수경성을 유발하는 자극효과가 현저히 저하되고, 200중량부를 초과하게 되면 자극효과는 증가하지 않아 경제적이지 못하다.
The portland cement is added to further increase the hydraulic properties of the slag powder is 100 to 200 parts by weight based on 100 parts by weight of the mixture produced through the first mixing step. When the Portland cement is less than 100 parts by weight, the irritation effect of causing hydraulic properties is remarkably lowered as in the case of the anhydrous gypsum, and when it exceeds 200 parts by weight, the irritation effect does not increase and it is not economical.
그리고, 상기 표면개질제는 분쇄중에 분체입자의 응집을 억제하여 분급효율 및 분쇄효율을 향상시키고, 분쇄기 내에서 피분쇄물의 흐름 특성을 향상시키며, 밀의 막힘 현상을 방지하여 과분쇄가 발생되지 않도록 함에 따라 불필요한 미분을 방지할 뿐만 아니라, 고체입자가 볼 매체나 내벽에 코팅되는 현상을 방지하여 볼의 충격력이 피분쇄물에 직접적으로 전달되도록 하면서 코팅물에 의한 충격력이 감소되는 것을 방지하고, 고체입자 표면에 작용기를 부여함에 따라 유동특성 및 경화특성을 개선시킨다.
In addition, the surface modifier suppresses agglomeration of powder particles during grinding, thereby improving classification efficiency and grinding efficiency, improving the flow characteristics of the powder to be milled in the grinder, and preventing clogging of the mill so that no overgrinding occurs. It not only prevents unnecessary fine powder, but also prevents the solid particles from being coated on the ball media or the inner wall, so that the impact force of the ball is directly transmitted to the to-be-ground object, and the impact force caused by the coating is not reduced. Imparting functional groups to improves flow and curing properties.
상기한 표면개질제는 EDIPA(N,N-Diisopropylethylamine), Diethylene Glycol, 소포제 및 Glycerine을 혼합하여 형성되는 것으로, 상기 표면개질제는 제 2혼화단계를 통해 생성된 혼합물 100중량부에 대하여 0.01 ~ 0.2중량부가 투입된다. 상기 표면개질제는 0.01중량부 미만이 되면 표면개질 효과가 저하되고, 0.2중량부를 초과하게 되면 표면개질 효과가 증가하지 않아 경제적이지 못하다.The surface modifier is formed by mixing EDIPA (N, N-Diisopropylethylamine), Diethylene Glycol, antifoaming agent and Glycerine, the surface modifier 0.01 to 0.2 parts by weight based on 100 parts by weight of the mixture produced through the second admixing step Is committed. When the surface modifier is less than 0.01 parts by weight, the surface modification effect is lowered, and when the surface modifier is more than 0.2 parts by weight, the surface modification effect does not increase and it is not economical.
상기 EDIPA(N,N-Diisopropylethylamine)를 설명하면, 일반적으로 시멘트 수화물과 같이 pH가 높은 경우 Fe의 용해도가 낮으며, 간극상 Fe성분도 클링커 입자의 주위에 비정질의 수화물 피막을 형성하고, 클링커 광물이 물과 접촉하는 것을 방해하게 된다. 따라서, 상기 EDIPA(N,N-Diisopropylethylamine)는 고급 아민 알콜계 물질로서 Fe와 선택적으로 반응하여 시멘트 조성광물인 CAAF의 수화반응을 촉진하고 실리케이트상이 물과 접촉할 수 있도록 유도하여 강도발현에 기여하며, 촉매작용으로 C4AF상과의 반응에 의해 소멸되지 않고 회수되어 미 반응 C4AF 및 간극수가 있는 한 반응이 계속 진행되도록 함에 따라, 시멘트의 초기 및 장기강도를 증대시켜주기 위하여 주용성분의 하나로 투입하는데, 이러한 EDIPA(N,N-Diisopropylethylamine)는 표면개질제의 전체 100중량%에 대하여 35중량% ~ 45중량%가 투입된다.Referring to the EDIPA (N, N-Diisopropylethylamine), in general, when the pH is high, such as cement hydrate, Fe solubility is low, the interphase Fe component also forms an amorphous hydrate film around the clinker particles, clinker minerals It will interfere with contact with water. Accordingly, the EDIPA (N, N-Diisopropylethylamine) is a higher amine alcohol-based material that selectively reacts with Fe to promote the hydration reaction of the cement composition mineral CAAF and induce the silicate phase to contact with water to contribute to the strength development In order to increase the initial and long-term strength of the cement, it is added as one of the main components, so that the reaction proceeds as long as there is unreacted C4AF and pore water. Such EDIPA (N, N-Diisopropylethylamine) is added to 35% to 45% by weight relative to the total 100% by weight of the surface modifier.
상기 EDIPA(N,N-Diisopropylethylamine)는 35중량% 미만이 되면 전술한 CAF4의 수화촉진 및 촉매작용이 부족하게 되고, 45중량%를 초과하게 되면 혼합물의 안정성이 저하될 뿐만 아니라, 첨가된 시멘트에 암모니아 냄새가 증가하여 분쇄공정 및 최종 시멘트 타설시 취기가 발생한다.
When the EDIPA (N, N-Diisopropylethylamine) is less than 35% by weight, the above-mentioned hydration promotion and catalysis of CAF4 is insufficient, and when the content exceeds 45% by weight, the stability of the mixture is lowered and added to the added cement. Increased odor of ammonia causes odor in the grinding process and final cement pouring.
상기 Diethylene Glycol은 광물의 미분쇄를 위해 투입되는 것으로, 이를 좀 더 자세히 설명하면 진동밀을 이용하여 제 2혼화단계를 통해 생성된 혼합물과 표면개질제를 분쇄시 피분쇄물이 일정한 입경으로 분쇄되면 입자 표면에 양전하로 하전되어 정전기적인 인력에 의한 입자들의 재응집 및 음으로 하전된 철구의 표면에 정전기적인 코팅현상이 발현되어 분쇄의 효과가 저하된다. 따라서, 상기 Diethylene Glycol은 말단기의 수산기들은 파분쇄물들 간에 물리적으로 흡착되어 입자 상호간의 반발력을 유도하게 되며, 이에 따라 상기 재응집 및 철구의 코팅현상을 억제하여 분쇄의 효율을 증대시킨다.The Diethylene Glycol is input for the fine grinding of minerals, which will be described in more detail. When the mixture is ground to a constant particle size when the mixture and the surface modifier generated through the second mixing step using a vibration mill are ground, The surface of the negatively charged iron ball recharges the particles due to electrostatic attraction due to the positive charge on the surface and the electrostatic coating phenomenon is expressed, thereby reducing the effect of grinding. Accordingly, the diethylene glycol is the hydroxyl groups of the end groups are physically adsorbed between the crushed products to induce repulsion between the particles, thereby increasing the efficiency of grinding by inhibiting the re-agglomeration and coating of the iron ball.
상기 Diethylene Glycol은 표면개질제의 전체 100중량%에 대하여 5중량% ~ 20중량%가 투입되는데, 이러한 Diethylene Glycol이 5중량% 미만이 되면 정전기적인 반발력 유도에 의한 입자의 분쇄효율 증대의 효과가 감소하며, 20중량%를 초과하게 되면 분쇄효율이 증가하지 않아 경제적이지 못하다.
Diethylene Glycol is added in an amount of 5% to 20% by weight relative to the total 100% by weight of the surface modifier, when the diethylene glycol is less than 5% by weight, the effect of increasing the grinding efficiency of the particles due to the electrostatic repulsive force is reduced If it exceeds 20% by weight, the grinding efficiency does not increase, so it is not economical.
상기 Diethylene glycol 및 EDIPA는 고급 알콜계 계면활성제의 일종으로 시멘트 수화반응시 표면에너지 저하에 기인하는 불균일한 기포의 발생을 유도하게 되어 시멘트의 정확한 공기량 조절을 어렵게 하며, 다량의 기포발생에 의한 시멘트의 내구성 저하를 일으킬 수 있다. 따라서, 상기 소포제는 물의 표면에너지를 향상시켜 시멘트 조성물의 수화반응에 의해 생성되는 기포의 발생을 억제하여 시멘트의 강도를 높여주는 역할을 하며, 이러한 소포제는 표면개질제의 전체 100중량%에 대하여 0.05중량% ~ 0.3중량%가 투입된다.
The diethylene glycol and EDIPA is a kind of higher alcoholic surfactant, which induces the generation of non-uniform bubbles due to surface energy degradation during cement hydration reaction, making it difficult to control the precise air amount of the cement, It may cause durability deterioration. Therefore, the antifoaming agent improves the surface energy of the water to suppress the generation of bubbles generated by the hydration reaction of the cement composition to increase the strength of the cement, such antifoaming agent 0.05% by weight relative to the total 100% by weight of the surface modifier % To 0.3% by weight is added.
상기 소포제가 0.05중량% 미만이 되면 물의 표면에너지 증가유도에 의한 불균일한 기포발생 억제력이 부족하며, 0.3중량% 이상이 되면 물의 표면에너지가 과도하게 증가되어 콘크리트 타설시 적절한 공기량 조절이 어려운 부작용이 발생되어 구조체 내의 내구성을 저하시키는 악영향을 미친다.
When the antifoaming agent is less than 0.05% by weight, there is a lack of suppression of non-uniform bubble generation due to the induction of surface energy increase of water, and when more than 0.3% by weight, the surface energy of the water is excessively increased, so that it is difficult to control air volume properly when concrete is poured. This adversely affects the durability in the structure.
상기 Glycerine은 상기 Diethylene glycol과 상호작용에 의해 분쇄효과를 증진시키며, 시멘트 및 콘크리트에 보습성을 향상시켜 콘크리트 타설시 작업성을 증대시키고, 시멘트의 수화반응 촉진에 의한 강도발현의 속도를 증대시켜준다.
The Glycerine enhances the grinding effect by interacting with the diethylene glycol, improves the moisturizing properties of cement and concrete, increases workability when placing concrete, and increases the speed of strength expression by promoting the hydration reaction of cement. .
상기 Glycerine은 표면개질제의 전체 100중량%에 대하여 35중량% ~ 50중량%가 투입되는데, 35중량% 미만이 되면 시멘트의 초기강도 촉진 및 분쇄효율 증가의 효과가 부족하며, 50중량% 미만이되면, 시멘트의 초기활성도가 과도하게 증대되어 원활한 시공이 곤란하다.
The Glycerine is 35 to 50% by weight relative to the total 100% by weight of the surface modifier, if less than 35% by weight lack the effect of promoting the initial strength of the cement and increase the grinding efficiency, if less than 50% by weight As the initial activity of cement is excessively increased, smooth construction is difficult.
위와 같이 기재된 본 발명의 고분말도 슬래그시멘트는 초기강도 및 장기강도가 증대됨에 따라 고강도 특성을 발휘하여 품질이 우수하며, 슬래그를 다량으로 함유할 수 있어 제품의 제조원가를 현저히 낮출 수 있으며, 유동특성 및 경화특성이 개선된 장점을 지닌다. As described above, the high-powder slag cement of the present invention exhibits high strength characteristics as the initial strength and the long-term strength are increased, and the slag cement may contain a large amount of slag, thereby significantly lowering the manufacturing cost of the product. It has the advantage of improved curing properties.
상기와 같은 장점을 지닌 본 발명의 고분말도 슬래그시멘트를 통해 공지의 PHC PILE을 제작하여 지반에 설치할 경우 구조물로부터 가해지는 하중을 안정적으로 지지하고, 토압이나 지반변형에 대해 강성을 가질 수 있어 구조적으로 안정성을 확보할 수 있으며, 이에 따라 지중에 안정적으로 정착할 수 있다.The high-molecular-weight slag cement of the present invention having the above-mentioned advantages can stably support the load applied from the structure when it is installed on the ground by making known PHC PILE, and can have rigidity against earth pressure or soil deformation. Stability can be secured and, therefore, stable settlement in the ground can be achieved.
