고로슬래그 몰탈 조성물{A composites for Blast-furnace slag mortar}A composites for Blast-furnace slag mortar}

본 발명은 고로슬래그 몰탈 조성물에 관한 것이다. 더욱 구체적으로, 제철소의 고로에서 선철을 제조할 때 발생하는 산업부산물인 고로슬래그에 알칼리성 물질을 단순 자극제인 〈NaOH, NaOH+NaCl, NaOH+CaCl2〉 를 첨가하여 고강도 고로슬래그 몰탈 조성물을 제조하는 방법과 자극제이면서 반응물인 〈Ca(OH)2, Ca(OH)2+NaCl, Ca(OH)2+CaCl2〉를 첨가하여 보통강도 고로슬래그 몰탈을 제조하는 방법으로 고로슬래그의 약한 자경성을 촉진시키고 잠재수경성과 포졸란 반응을 진행시켜 고로슬래그를 주성분으로 하여 보통강도영역에서 고강도영역까지 소요의 강도를 확보하며 시멘트와 비교하여 동등 혹은 이상의 강도를 가지는 "고로슬래그 몰탈 조성물"에 관한 것이다.The present invention relates to a blast furnace slag mortar composition. More specifically, to prepare a high-strength blast furnace slag mortar composition by adding an alkaline substance as a simple stimulant <NaOH, NaOH + NaCl, NaOH + CaCl 2 > to the blast furnace slag which is an industrial by-product generated when manufacturing pig iron in the blast furnace of the steelworks The weak magnetic hardness of blast furnace slag is prepared by adding stimulant and reactants 〈Ca (OH) 2 , Ca (OH) 2 + NaCl, Ca (OH) 2 + CaCl 2 〉. The present invention relates to a "blast furnace slag mortar composition" having a strength equal to or higher than that of cement, by securing the required strength from the normal strength zone to the high strength zone by promoting the latent hydrophobicity and pozzolanic reaction.

일반적으로 고로슬래그는 용융상태의 고온 슬래그를 물, 공기 등으로 급냉하여 입상화한 것이다. 고로슬래그는 잠재수경성 물질이므로 포틀랜드시멘트 크링카 광물과 같이 물과 접할 때 자기촉발적인 수화반응을 개시하지 않는다.In general, blast furnace slag is granulated by quenching molten hot slag with water, air or the like. Since blast furnace slag is a latent hydraulic material, it does not initiate self-induced hydration when in contact with water, such as the Portland Cement Krinka mineral.

이와 같은 고로슬래그 특성상 단일 성분만으로 소요의 강도를 확보한 고로슬래그 몰탈의 실용화 정도까지는 개발하지 못하고 있다. 대신에, 콘크리트용 혼화재료로서 고로슬래그를 사용하여 장기강도증진, 내화학저항성, 알칼리 골재반응 억제효과, 수화열 저감등의 목적에 이용되고 있다.Due to the characteristics of blast furnace slag, it has not been developed until the degree of practical use of blast furnace slag mortar having secured the required strength with only a single component. Instead, blast furnace slag is used as a mixed material for concrete, and is used for the purpose of increasing long-term strength, chemical resistance, inhibiting alkali aggregate reaction, and reducing hydration heat.

따라서, 본 발명자는 산업부산물인 고로슬래그에 알칼리성 물질을 자극제로 사용함으로써 자경성을 촉진시키고 잠재수경성과 포졸란 반응을 진행시켜 종전의 고로슬래그의 주 용도인 콘크리트용 혼화재료로서뿐만 아니라 고로슬래그 단일 성분만으로 보통강도영역에서 고강도영역까지 소요의 강도를 확보하여 다양하게 사용될 수 있는 고로슬래그 몰탈 조성물을 개발하게 되었다.Therefore, the present inventors promote the hardening of the blast furnace slag, which is an industrial by-product, as a stimulant, and promote the latent hydrophobicity and the pozzolanic reaction. It has been developed a blast furnace slag mortar composition that can be used in various ways by securing the required strength from the normal strength region to the high strength region.

[발명의 목적][Purpose of invention]

본 발명의 목적은 첫째, 산업부산물인 고로슬래그에 알칼리성 물질을 단순 자극제인 〈NaOH, NaOH+NaCl, NaOH+CaCl2〉 를 첨가하여 고강도 고로슬래그 몰탈 조성물을 제조하는 방법과 자극제이면서 반응물인 〈Ca(OH)2, Ca(OH)2+NaCl, Ca(OH)2+CaCl2〉 를 첨가하여 보통강도 고로슬래그 몰탈을 제조하는 방법으로, 고로슬래그의 약한 자경성을 촉진시키고 잠재수경성과 포졸란 반응을 진행시켜 고로슬래그를 주성분으로 하여 보통강도영역에서 고강도영역까지 소요의 강도를 확보하는 고로슬래그 몰탈 조성물을 제공하는 것이다.The object of the present invention is first, a method of preparing a high strength blast furnace slag mortar composition by adding an alkaline substance to the industrial by-product blast furnace slag as a simple stimulant <NaOH, NaOH + NaCl, NaOH + CaCl 2 > and a stimulant and reactant <Ca (OH) 2 , Ca (OH) 2 + NaCl, Ca (OH) 2 + CaCl 2 〉 to make blast furnace slag mortar with moderate strength. It is to provide a blast furnace slag mortar composition to ensure the required strength from the normal strength region to the high strength region by using the blast furnace slag as a main component.

둘째, 콘크리트용 혼화재료로 주로 사용되고 있는 고로슬래그에 알칼리성 물질을 자극제로 첨가하여 고로슬래그를 주성분으로 하여 소요의 강도를 확보함으로써 고로슬래그의 사용 범위를 확대 시킬 수 있는 고로슬래그 몰탈 조성물을 제공하는 것이다.Second, to provide blast furnace slag mortar composition which can expand the scope of blast furnace slag by securing the required strength by adding alkaline substance as stimulant to blast furnace slag which is mainly used as concrete admixture as a stimulant. .

셋째, 산업부산물인 고로슬래그를 재활용함으로써 시멘트 대체효과를 거두어 시멘트 제조시 발생하는 CO2배출량 및 소성에 필요한 에너지를 감소 시킬 수 있는 고로슬래그 몰탈 조성물을 제공하는 것이다.Third, to provide a blast furnace slag mortar composition that can reduce the energy required for the CO 2 emissions and sintering produced by cement production by recycling the blast furnace slag as an industrial by-product.

본 발명인 산업부산물인 고로슬래그에 알칼리성 물질을 단순 자극제〈NaOH, NaOH+NaCl, NaOH+CaCl2〉와 자극제이면서 반응물인 〈Ca(OH)2, Ca(OH)2+ NaCl, Ca(OH)2+ CaCl2〉 를 고로슬래그에 중량 비율로 첨가하였다.An alkaline substance was added to the blast furnace slag, an industrial by-product of the present invention, with a simple stimulant <NaOH, NaOH + NaCl, NaOH + CaCl 2 > and a stimulant and reactant <Ca (OH) 2 , Ca (OH) 2 + NaCl, Ca (OH) 2. + CaCl 2 > was added to the blast furnace slag in weight ratio.

고로슬래그 몰탈 조성물은 고로슬래그 단일 성분만을 사용한 고로슬래그 중량 100%에 알칼리성 자극제를 0.1∼18%첨가하여 제조한 것으로 고로슬래그의 자경성을 촉진시키고 잠재수경성과 포졸란 반응을 진행시킨다.The blast furnace slag mortar composition is prepared by adding 0.1-18% of an alkaline stimulant to 100% of blast furnace slag using only blast furnace slag components to promote the hardening of the blast furnace slag and to promote the potential hydrophobicity and the pozzolanic reaction.

상기 고로슬래그는 시멘트 등의 혼합재를 사용하지 않고 단일 성분의 고로슬래그만으로 보통강도에서 고강도영역까지 소요의 강도를 확보하기 위해 알칼리성 물질을 단순 자극제인 〈NaOH, NaOH+NaCl, NaOH + CaCl2〉 를 첨가하여 고강도 고로슬래그 몰탈 조성물을 제조하는 방법과 자극제이면서 반응물인 〈Ca(OH)2, Ca(OH)2+NaCl, Ca(OH)2+CaCl2〉 를 첨가하여 보통강도 고로슬래그 몰탈을 제조하는 방법으로 고로슬래그를 물과 혼합하여 보통강도영역에서 고강도영역까지 소요의 강도를 확보하는 경화체를 형성하게 된다.The blast furnace slag does not use a mixture of cement or the like and only a single blast furnace slag is used as a simple stimulant, 〈NaOH, NaOH + NaCl, NaOH + CaCl 2 〉, in order to secure the required strength from the normal strength to the high strength region. To prepare a high strength blast furnace slag mortar composition and to add a stimulant and reactants 〈Ca (OH) 2 , Ca (OH) 2 + NaCl, Ca (OH) 2 + CaCl 2 〉 to prepare a moderate strength blast furnace slag mortar. By mixing the blast furnace slag with water to form a hardened body to secure the required strength from the normal strength region to the high strength region.

고로슬래그는 물과 접촉하면 CaO 성분이 우선적으로 용출하고 슬래그 표면이 SiO2, Al2O3성분으로 가득찬 비정질생성층으로 덮혀 그 후 반응의 진행을 저해하며 이러한 불투수성의 산성피막은 강알칼리에 의해 피막을 파괴하여야만 반응이 계속 진행된다.The blast furnace slag is first eluted with CaO component in contact with water and the surface of the slag is covered with an amorphous layer filled with SiO 2 , Al 2 O 3 component to inhibit the progress of the reaction afterwards. The reaction continues only if the film is destroyed.

고로슬래그가 나타내는 약한 자경성은 슬래그로부터 CaO성분이 서서히 용출하는 것에 의한 PH상승이 주원인이며 고로슬래그 중에 포함된 소량의 Na, K이온등이 용출해서 약한 자경성을 촉진시킬 수도 있다.The weak self-hardening exhibited by blast furnace slag is mainly caused by the pH increase due to the slowly eluting CaO component from the slag, and a small amount of Na and K ions contained in the blast furnace slag can be eluted to promote weak magnetic hardening.

상기의 고로슬래그와 알칼리성 물질의 자극제와의 반응으로 고로슬래그의 강도를 보통강도에서 고강도까지 조정할 수 있으며, 사용 적절한 고로슬래그 몰탈 조성물을 제조할 수 있다.By the reaction of the blast furnace slag with the stimulant of the alkaline material, the strength of the blast furnace slag can be adjusted from the normal strength to high strength, it is possible to prepare a suitable blast furnace slag mortar composition.

상기의 고로슬래그 몰탈 조성물의 물성을 측정하기 위해 고로슬래그 단일 성분에 알칼리성 자극제를 0.1∼18%첨가하여 실험한 물성실험은 실시한 예.1 다음과 같다.In order to measure the physical properties of the blast furnace slag mortar composition, a physical property test conducted by adding 0.1-18% of an alkaline stimulant to the blast furnace slag single component was carried out.
