Abstract

PURPOSE: A three-component non-plastic clay mortar composition is provided to impart good release-resistant against water and desired strength by adding specific alkaline stimulator to a mixture of the natural clay and blast furnace slag as the industrial by-product. CONSTITUTION: The three-component composition comprises 50-90 wt.% of clay, 10-50 wt.% of limestone(Ca(OH)2) and 10-50 wt.% of the blast furnace slag and is added with 1-6 wt.% of alkaline stimulator such as NaOH, Ca(OH)2+CaCl2 with no addition of cement material. The clay containing microfine ions and the limestone can generate the aggregation and pozzolane reaction of ions. Additionally, the alkaline component and the microfine ions in the clay together can aggregate and progress the potential water-curing reaction to ensure desired strength and to prevent the release of product in water.

Description

3성분계(점토, 석회, 고로슬래그)비소성 점토모르터 조성물{A Clay-mortar composites of non-heating with 3 types powder groups(clay mineral, Lime, Blast furnace slag)}A Clay-mortar composites of non-heating with 3 types powder groups (clay mineral, Lime, Blast furnace slag)}

본 발명은 3성분계(점토, 석회, 고로슬래그)비소성 점토모르터 조성물에 관한 것이다.The present invention relates to a three component system (clay, lime, blast furnace slag) non-plastic clay mortar composition.

더욱 구체적으로, 천연상태의 점토(제1차 점토 및 제2차 점토 모두 포함)에 석회(Ca(OH)2)와 고로슬래그 및 고로슬래그의 잠재수경성질을 개선하기 위해 알칼리자극제로 NaOH를 고로슬래그 중량의 6%이내, Ca(OH)2+CaCl2를 고로슬래그 중량의 6% 이내로 첨가함으로써 점토를 소성하지 않고도 3성분계(점토, 석회(Ca(OH)2), 고로슬래그)간의 반응과 고로슬래그와 알칼리자극제와의 반응으로 소정의 강도를 확보하고 풀림을 방지할 수 있게 한 것이다.More specifically, in the natural clay (including both primary and secondary clays), lime (Ca (OH) 2) and NaOH as an alkali stimulant to improve the latent hydraulic properties of blast furnace slag and blast furnace slag By adding Ca (OH) 2 + CaCl 2 to within 6% of the blast furnace slag within 6% of the slag weight, the reaction between the three component systems (clay, lime (Ca (OH) 2 ), blast furnace slag) without burning the clay The reaction between the blast furnace slag and the alkali stimulant ensures a predetermined strength and prevents loosening.

일반적으로 점토는 내화물 또는 소성점토로만 국한되어 사용되었다. 바꿔말하면, 점토만으로는 소정의 강도, 내수성, 수밀성 및 내구성이 약하기 때문에, 소성과정을 거쳐 세라믹 제품으로 완성한 후 건축용 및 세라믹용 재료로 사용된다.In general, clay was used only by refractory or calcined clay. In other words, clay alone is weak in predetermined strength, water resistance, watertightness and durability, and thus is used as a material for construction and ceramics after finishing a ceramic product through a firing process.

상기 소성과정은 높은 고열(종래에는 통상 1000℃이상 고온 소성)에 의한 점토조직의 용융으로 융착하여 견고한 유리질 재료로 만듦으로써, 물의 풀림저항성 확보와 소정의 강도를 확보하기 위한 과정이다. 그러나, 이러한 소성과정시 고온으로 높이기 위해서는 필연적으로 연료의 연소에 의한 에너지 소비가 필수적이고 또한, 연료의 연소시에 유해물질이 대기 중에 방출되어 환경오염을 일으키는 매우 큰 단점이 있다.The firing process is a process for securing the loosening resistance of the water and securing a predetermined strength by fusion by melting the clay structure by high heat (conventionally, high temperature firing, usually 1000 ° C. or higher) to form a rigid glassy material. However, in order to increase the temperature to a high temperature during the firing process, energy consumption by the combustion of fuel is inevitably necessary, and there is a very big disadvantage that harmful substances are released into the air during combustion of the fuel, causing environmental pollution.

따라서, 본 발명자는 국내에 풍부하게 매장되어 있는 점토를 소성과정을 거치지 않고 고결하여 소정의 강도를 확보할 수 있는 3성분계(점토, 석회(Ca(OH)2, 고로슬래그)비소성 점토모르터 조성물을 개발하게 되었다. 즉, 소성하지 않은 천연의 점토에 석회(Ca(OH2), 고로슬래그를 첨가하고 여기에 고로슬래그의 알칼리 자극제인 NaOH, Ca(OH)2+CaCl2를 첨가하여 물에 대한 풀림저항성 확보와 소정의 강도를 확보한 조성물을 개발하는 것이다.Therefore, the present inventors solidify the clay buried abundantly in the country without undergoing a firing process, three-component system (clay, lime (Ca (OH) 2 , blast furnace slag) non-plastic clay mortar composition to secure a predetermined strength In other words, lime (Ca (OH 2 ) and blast furnace slag were added to unburned natural clay and NaOH and Ca (OH) 2 + CaCl 2 , alkali stimulants of blast furnace slag, were added to water. It is to develop a composition that secures the annealing resistance and secures a predetermined strength.

본 발명의 목적은 석회가 들어가지 않은 2성분계(점토, 고로슬래그)의 경우 응결불능 및 물풀림이 다소 발생하였으며, 낮은 강도를 보인 반면, 본 발명인 3성분계(점토, 석회(Ca(OH)2), 고로슬래그)의 경우 낮은 강도를 높여주기 위해 석회(Ca(OH)2)를 첨가하여 조성물을 제조하는 것과 더불어, 고로슬래그의 잠재수경성을 자극하여 수경성이 될 수 있도록 알칼리자극제 NaOH, Ca(OH)2+CaCl2로 구성되는 점토 조성물을 제조함으로써, 점토의 소성과정을 거치지 않고서도 고결하여 소정의 강도를 확보하며, 풀림을 방지할 수 있는 "3성분계 비소성 점토모르터 조성물"을 제조하는 것이다.The purpose of the present invention is a two-component system (clay, blast furnace slag) that does not contain lime, the condensation and water loosening occurred somewhat, while showing a low strength, the three-component system (clay, lime (Ca (OH) 2 ) ), In the case of blast furnace slag) in addition to preparing a composition by adding lime (Ca (OH) 2 ) to increase the low strength, alkali stimulants NaOH, Ca ( By preparing a clay composition consisting of OH) 2 + CaCl 2 , it is solidified without going through the firing process of clay to secure a predetermined strength, and to prepare a "three-component non-fired clay motor composition" which can prevent loosening. will be.

본 발명인 점토, 석회(Ca(OH)2), 고로슬래그,를 첨가한 3성분계 비소성 점토모르터 조성물은 점토 및 석회(Ca(OH)2), 고로슬래그와 고로슬래그의 알칼리자극제인 NaOH, Ca(OH)2+CaCl2를 소정의 중량비율로 혼합하여 제조한 점토와 석회, 고로슬래그의 혼합체로 구성된다.The three-component non-fired clay mortar composition to which the present invention clay, lime (Ca (OH) 2 ), blast furnace slag is added is an alkali stimulant of clay and lime (Ca (OH) 2 ), blast furnace slag and blast furnace slag. It consists of a mixture of clay, lime and blast furnace slag prepared by mixing (OH) 2 + CaCl 2 in a predetermined weight ratio.

상기 점토는 제1차 점토 및 제2차 점토, 진흙, 황토, 고령토 등과 같은 일반적 개념의 모든 흙을 지칭한다.The clay refers to all soils of general concept such as primary and secondary clays, mud, loess, kaolin and the like.

상기 3성분계(점토, 석회(Ca(OH)2, 고로슬래그)의 비소성 점토모르터 조성물은 보통강도영역의 모르터와 고강도영역 모르터로 구분된다.The non-fired clay mortar composition of the three-component system (clay, lime (Ca (OH) 2 , blast furnace slag) is divided into a mortar of a normal strength region and a mortar of a high strength region.

It is prepared by mixing an alkali stimulant of 1 to 6% of the blast furnace slag weight.

점토의 미세립자 이온과 석회는 이온의 응집반응 및 포졸란 반응을 일으키고 고로슬래그는 알칼리자극제와 물에서 반응하여 수경성을 나타내고 경화되며 또한, 알칼리용액 성분은 점토의 미세립자 이온과의 응집반응 및 잠재수경성 반응을 일으켜서 점토를 소성하지 않고도 소정의 강도를 확보하고 풀림을 방지할 수 있게 된다.The fine particle ions and lime of clay cause the coagulation and pozzolanic reaction of ions, and the blast furnace slag reacts with alkali stimulant in water to show hydraulicity and harden.In addition, the alkaline solution component coagulates with the fine particle ions of clay and the latent hydraulic By causing a reaction, it is possible to secure a predetermined strength and prevent loosening without firing clay.
