본 발명은 고유동성 및 접착력이 향상된 셀프 레벨링 바닥용 모르타르 및 그 제조방법에 관한 것으로서, 보다 구체적으로, 유동성은 물론, 압축강도, 휨강도, 접착강도가 우수하고 내구성이 향상된 셀프 레벨링 바닥용 모르타르 및 그 제조방법에 관한 것이다.The present invention relates to a self-leveling floor mortar improved in fluidity and adhesion, and more particularly, to a self-leveling floor mortar having excellent fluidity, excellent compression strength, flexural strength and adhesive strength and improved durability, And a manufacturing method thereof.

최근에 들어 재료적 요인과, 생산성, 작업성 향상을 위하여 물을 다량 사용하는 레미콘의 공급에 따른 콘크리트 조직의 다공질화 등과 같은 시공적 요인 및 산성비, 급속적인 자동차 또는 공장의 증가로 인한 공기 중 CO2 농도의 증가, 겨울철 결빙방지를 위한 염화칼슘의 다량 사용 등과 같은 환경적 요인 때문에, 알칼리골재반응, 동해, 염해 또는 중성화(탄산화) 등과 같은 노후화 현상이 조기에 발생하거나, 과도한 알칼리 성분(예를 들어, 수산화칼슘이나 황산나트륨 등)이 수분과 반응하여 용해되어 나오는 백화(EFFLORESCENCE)현상에 따른 표면 오염과, 이에 따른 콘크리트의 알칼리성 소실로 인한 철근의 발청(녹 발생), 이로 인하여 발생하는 팽창압력에 의한 표면 콘크리트에서의 균열발생, 들뜸이나 탈락 등과 같은 결함이 발생하여, 결과적으로 구조내력이 저하되고, 누수가 생기는 등의 치명적인 결함으로 이어진다.In recent years, there has been a tendency to increase the amount of CO in the air due to factors such as material factors, construction factors such as porosity of concrete structure due to the supply of concrete using a large amount of water and acid rain, 2 concentration, and the use of large amounts of calcium chloride to prevent winter icing, etc., an aging phenomenon such as alkali aggregate reaction, frost damage, salting or neutralization (carbonation) may occur prematurely or excessive alkali components (Rust) due to alkaline disappearance of concrete due to surface contamination due to the phenomenon of EFFLORESCENCE, which is caused by the dissolution of water due to the reaction of water with calcium hydroxide or sodium sulfate, and the surface caused by the expansion pressure Cracks in the concrete, defects such as lifting or dropping occur, and as a result, Resulting in a fatal defect such as a leakage, leakage, or the like.

한편, 자기 수평성(셀프 레벨링, self leveling) 모르타르의 조성물을 이용하는 셀프 레벨링 칼라 마감재에 관한 자료나 특허가 다수 공개되어 있고 현장에서 적용하고 있다. 하지만, 재료의 특성은 자기 수평성을 가지지만, 실제 현장에 적용하면, 피착재의 특성에 따라 자기 수평을 잘 이루어지지 않는다. 또한, 수평성에 치중한 나머지 하지와의 접착력이 부족하여 박리되는 현상이 발생하거나 균열이 발생할 소지가 있다. 이에 따라, 단순한 시멘트계의 마감으로는 최종 칼라 마감재로서의 기능을 가질 수 없고 그 상단에 또 다른 칼라 마감재로 시공해야하는 이중적인 어려움이 있다.On the other hand, many data and patents on self-leveling color finishing materials using a composition of self-leveling mortar are disclosed and applied in the field. However, the characteristics of the material have self-leveling, but when applied to actual field, the self-leveling is not performed well depending on the characteristics of the adhered material. In addition, there is a possibility that peeling may occur or cracks may occur due to insufficient adhesive strength to the remaining base, which is centered on the horizontal property. Accordingly, there is a double difficulty in that a simple cementitious finish can not have a function as a final color finishing material and another color finishing material should be applied to the top of the cementitious finish.

또한, 모르타르를 이용한 바닥 마감 공법은 그 시공비가 저렴하고 시공이 용이하여 지금까지 공장바닥 등의 공업용 건축물과 물류 센터, 옥내 주차장 등 상업용 건축물에 일반적인 바닥 마감 공법으로 사용되어 왔다. 그러나, 모르타르를 이용한 바닥 마감 공법은 저렴한 시공비와 시공의 용이성 때문에 많이 사용되어 오고 있지만, 시멘트 모르타르만을 사용할 경우 표면 경도가 약하여 파손되기 쉬우며, 구체와 부착력이 떨어져 부착 계면에서 탈락이 발생되기 쉽다. 또한, 시멘트 모르타르를 사용할 경우 표면에서 급격한 수분증발로 인한 초기 소성균열이 발생되기 쉽다.In addition, the floor finishing method using mortar has been used as a general floor finishing method for industrial buildings such as floor of a factory, a commercial center such as a distribution center, and indoor parking lot so far, because the construction cost is low and the construction is easy. However, the floor finishing method using mortar has been widely used because of low installation cost and ease of construction. However, when only cement mortar is used, the surface hardness is weak and is easily broken. Also, when cement mortar is used, initial plastic cracking is likely to occur due to rapid water evaporation on the surface.
