단섬유보강 고인성 시멘트복합재료의 제조방법{Manufacturing Method of High Ductility Cement Based Reinforced with Shot Fibers}Manufacturing Method of High Ductility Cement Based Reinforced with Shot Fibers}

본 발명은 기존의 시멘트콘크리트가 가진 취성적 성질을 대폭적으로 개선할 수 있을 뿐만 아니라 기존 섬유보강콘크리트의 휨 및 인장인성을 더욱 향상시킬 수 있는 단섬유보강 고인성 시멘트복합재료에 관한 것으로, 본 발명의 단섬유보강 고인성 시멘트복합재료는 매트릭스, 섬유 및 매트릭스와 섬유의 계면특성을 적절하게 개선 조절함으로서 기존의 시멘트콘크리트 또는 섬유보강콘크리트와는 달리 휨 또는 인장력을 받을 경우 초기균열발생 이후에도 응력의 급격한 저하가 발생하지 않고 변형이 증대함에 따라 응력이 증가하는 의사변형경화특성과 균열발생시 무수한 미세균열이 전체적으로 분산 발생하는 멀티플크랙 특성을 가지고 있어 휨 및 인장응력에 의한 균열폭 제어효과, 유해물질 침투억제효과, 박리저항성, 높은 에너지 흡수능력 및 피로내구성을 발휘할 수 있는 시멘트복합재료이다.The present invention relates to a short fiber reinforced high toughness cement composite material which can not only significantly improve the brittleness of the existing cement concrete but also further improve the bending and tensile toughness of the existing fiber reinforced concrete. The short-fiber reinforced high toughness cement composites are designed to improve the interfacial properties of matrices, fibers and matrices, and to improve the interfacial properties of the fibers. Pseudo-hardening hardening property that stress increases as deformation increases without deterioration, and multiple cracking property in which numerous microcracks are dispersed as a whole when cracking occurs, so crack width control effect due to bending and tensile stress and inhibition of harmful substance penetration , Peeling resistance, high energy absorption capacity and A cement composite material that exhibits durability.

지금까지 기존의 콘크리트 및 모르터와 같은 시멘트계 재료는 대부분 압축성능을 향상시키기 위한 개발만이 진행되어 매우 높은 압축강도를 발현할 수 있는 고강도의 모르터 및 콘크리트의 제조가 가능하게 되었지만 이 경우에도 휨강도 및 인장강도가 매우 낮고, 또한 강한 취성적 성질로 인해 파괴시 균열발생 후 급격한 응력저하가 발생하며, 철근 등에 의해 보강된 경우에도 균열이 일부에만 국한적으로 발생되어 구조물의 구조성능 및 내구성에 많은 문제점을 나타내고 있다. 한편 이를 보완하기 위해 최근에는 다양한 섬유보강콘크리트가 개발되고 있으나 대부분이 휨성능의 향상, 균열억제만을 목적으로 하고 있어 구조물에 높은 휨 및 인장인성을 부여하지 못하며, 또한 시공성 저하, 복잡한 제조공정 등의 이유로 일부에만 국한되어 사용되고 있는 실정이다.Until now, most cement-based materials such as concrete and mortar have been developed only to improve compressive performance, so that it is possible to manufacture high-strength mortar and concrete that can express very high compressive strength, but even in this case, bending strength and tension Due to its very low strength and strong brittleness, there is a sudden drop in stress after cracking, and even when reinforced by reinforcing bars, cracks are generated only in part, which causes many problems in structural performance and durability. It is shown. Recently, various fiber-reinforced concretes have been developed to compensate for this, but most of them are aimed only at improving bending performance and preventing cracking, and thus do not impart high bending and tensile toughness to the structure. For some reason, it is used only in part.

본 발명은 단섬유보강 고인성 시멘트복합재료의 제조방법에 관한 것으로 주요 구성재료인 매트릭스의 강도 및 파괴특성, 섬유의 강도, 섬유와 매트릭스의 부착특성, 섬유혼입량 등을 조절함으로서 휨 및 인장응력 하에서 초기균열이 발생한 후에도 균열면의 섬유가교에 의해 다수의 미세균열인 멀티플크랙을 발생시키고 수%의 변형도까지 초기균열시 응력도를 유지 또는 상승시킬 수 있는 의사변형경화거동을 발휘할 수 있다.The present invention relates to a method for producing a short fiber reinforced high toughness cement composite material, which is characterized by bending and tensile stress by controlling the strength and fracture properties of the matrix, the strength of the fiber, the adhesion properties of the fiber and the matrix, and the amount of fiber mixed. Even after the initial crack occurs, it is possible to exhibit a pseudo-strain hardening behavior that can generate multiple cracks, which are a plurality of microcracks, and maintain or increase the stress during initial cracking up to several percent by the fiber cross-linking of the cracked surface.

이러한 멀티플크랙 및 의사변형경화거동 등의 단섬유보강 고인성 시멘트복합재료의 특징에 의해 휨응력이 작용하는 구조부재에서 휨균열폭을 억제할 수 있고, 초기균열 등의 손실에 대하여 안전성의 허용도를 향상시킬 수 있으며, 에너지흡수능력의 향상, 균열분산성 및 균열폭 억제에 의해 물을 매개로 한 유해물질 침투억제, 변형성능 향상에 의한 강재 및 부재의 변형성능 향상, 굴절균열구속에 의한 박리저항성의 향상 등의 효과를 발휘할 수 있는 단섬유보강 고인성 시멘트복합재료의 제조방법을 개발하고자 한다.Due to the characteristics of short-fiber reinforced high toughness cement composite materials such as multiple cracks and pseudo-strain hardening behavior, the flexural crack width can be suppressed in structural members with flexural stress, and safety tolerance is improved against loss of initial cracking. Increasing energy absorption capacity, inhibiting crack dispersibility and crack width, inhibits penetration of harmful substances through water, improves deformation performance of steel and members by improving deformation performance, and improves peel resistance by refractive cracking. To develop a method of manufacturing short fiber reinforced high toughness cement composites that can exert such effects.

Alternatively, the crack width generated in the member can be suppressed by the occurrence of multiple cracks, and the pseudo-strain hardening behavior can greatly improve the tolerance of the member against loss such as initial cracking, and the energy absorption ability It is greatly improved and applied to face members such as walls to reduce the response displacement of the structure as a whole and reduce the loss of other components. In addition, it is possible to suppress the penetration of harmful substances through water by suppressing crack dispersibility and crack width, thereby improving durability and watertightness against salt, freeze-thawing, chemical corrosion, etc., and deformation of steel materials and members by high deformation performance. The performance can be improved, and the effect of improving the peeling resistance of the concrete fragments can be exerted by the refractive crack arrest.
