  • 이노가닉 폴리머 콘크리트는 비소성 알카리 활성화 콘크리트의 일종으로 여러 가지 우수한 성능을 가지고 있으며, 그 중에서도 고온에서의 열적특성이 우수한 것으로 알려져 있다. 이에 따라, 이노가닉 폴리머 콘크리트를 이용한 경량패널을 제조하여, 소형가열로 내화시험을 측정한 결과 3시간 가열후 이면상승온도가 평균 82℃ 이하로 확인되어 공동주택의 내화벽체로 활용이 가능할 것으로 판단된다.

  • Repair and rehabilitation of existing structures is becoming a major part of construction, both in the industrially developed and developing countries. Advanced high strength composites are being utilized more and more for these applications because they are much stronger than steel, non-corrosive, and light. The light weight reduces the construction cost and time sustantially. The fibers are normally made of aramid, carbon, or glass and the binders are typically epoxies or esters. One major disadvantage of these composites is the vulnerability to fire. In most instance, the temperature cannot exceed $300^{\cire}C$. Since carbon and glass can substain high temperatures, an inorganic polymer is being evaluated for use as a matrix. The matrix can sustain more than $1000^{\cire}C$. The results reported in this paper deal with the mechanical properties of carbon composites made with the inorganic polymer and the behavior strengthened reinforced concrete beams. The results indicate that the new matrix can be successfully utilized for a number of applications.

  • In this paper, various of experiments were performed for checking the usefulness of Pozzolan Inorganic Polymer(PIP) Waterproof Admixture. The results of the experiment enabled to set the optimum mixture ratio of PIP waterproof admixture as 3.5%. Then, the test specimen mixed with PIP waterproof admixture was produced and consider whether meeting the quality standard of waterproofing admixture for concrete (KS F 4926) From the results, all the items such as mechanical properties and durability were meet the quality standard of KS. The PIP waterproof admixture concrete shows the high resistance of absorption, permeability and chloride ion penetration thanks to its internal components such as siliceous powder, zinc stearate and dispersive polymer.

  • In this study, durability of the nano-level inorganic polymer based coatings which can provide a barrier against the ingress of moisture or aggressive ions to concrete is discussed. For the durability evaluation of the coatings, chloride penetration test, accelerating carbonation test, freezing and thawing test, and sulfate ponding test are conducted. As the result of this study, concrete applied nano-level inorganic polymer based coatings has a much higher resistance to the ingress of chloride ion, carbon dioxide, moisture and aggressive acid than plain concrete and epoxy resin based paint by means of crosslinking three-dimensional structure with concrete structure.

  • Polymer cement is made by the modifying ordinary cement concrete with polymer additive. Until now polymer cement concrete is not used for the structural member, but it is growing to be considered as developing uses such as a waterproof of roof slab, the structural member for protecting corrosion, and a road pavement. The plymer cement concrete, being used for those uses, is superior to the cement concrete against the inorganic, organic acid, salt of acetic acid and organic solvents generally. In this paper, the polymer cement concrete was made by the ratio of 1:1 of sands and tailing in fine aggregate in order to solve the environmental pollution which causes the social problem by the tailing, It was measured for the compressive strength, flexural strength, and chemicals resistance was tested by dealing with 10% HCI, 20% NaOH and 10% NaCl aqueous solution.

  • Admixture compounds for reducing setting time and accelerating early strength development of redispersible polymer powder-modified mortars were made by mixing various inorganic accelerating inorganic materials. Redispersible polymer powder-modified mortars are prepared with various accelerator contents, and it was tested for setting time, flexural and compressive strengths. As a result, the accelerators contribute to strength development of the mortars in the early curing age of 12h or less. In the viewpoint of early strength development of redispersible polymer powder-modified mortars, an accelerator content of $20\%$ is recommended.

  • 본 연구에서는 시멘트 결합재를 사용하는 모르타르의 성능개선을 위한 방법으로 무기폴리머 결합재를 사용한 모르타르에 있어서 무기폴리머 결합재의 Si/Al 몰비에 따른 물리적 특성변화를 확인하고자 하였다. 무기폴리머 결합재는 주성분이 Si와 Al로 구성되어 있으며 이 성분들의 혼합비에 따라 물리적, 화학적 성능에 있어서 큰 차이가 나타나는 것으로 알려져 있다. 따라서 Si와 Al의 혼합 구성비에 따른 모르타르의 물리적 성능에 대한 영향연구에 관한 기초 근거자료를 재공하고자 평가를 실시하였다. 그 결과, 무기폴리머 결합재의 Si/Al 몰비가 증가할수록 조기강도는 증가하나 급격한 반응으로 작업성이 저하되며 28일 재령 확인결과 Si/Al 몰비가 2.61 이상인 경우에 수축현상이 심해지는 것으로 확인되었다. 그리고 무기폴리머 결합재의 Si/Al 몰비가 $2.43{\sim}2.61$ 범위내인 경우 상용 폴리머 시멘트 모르타르와 비교시 압축강도가 재령7일차에는 32% 이상 증가하는 것을 확인하였으며 재령 28일차에는 12% 이상 증가하는 것을 확인하였다.

  • Zero-energy construction is being emphasized due to environmental pollution. However, in the case of external insulation using organic insulation with good insulation performance, there are many studies on inorganic insulation as it shows limitations on fire stability. In addition, as the demand for stone for exterior walls increases, Cellular Light -weight Concrete(CLC) with polymer is used to supplement fire stability and insulation performance, and the construction of stone is complemented by combining organic insulation, inorganic insulation, and stone. In this study, the compressive strength and adhesion in tension of CLC are studied. As a result of the experiment, the compressive strength of 28 days according to the polymer addition rate did not change. The adhesion in tension according to the polymer addition rate tends to increase as the addition rate increases. The target adhesion in tension is 0.8 MPa, but the maximum value of the experiment did not reach the target value, and further research was needed to combine to maintain the density and improve the adhesion in tension.

  • Recently, polymer-clay hybrid materials have received considerable attention from both a fundamental research and application point of view. This organ-inorganic hybrid, which contains a nanoscale dispersion of the layered silicates, is a material with greatly improved thermal and mechanical characteristics. Two classes of nanocomposites were synthesized using an unsaturated polyester resin as the matrix and sodium montmorillonite as well as an organically modified montmorillonite as the reinforcing agents. X -ray diffraction pattern of the composites showed that the interlayer spacing of the modified montmorillonite were exfoliated in polymer matrix. The mechanical properties also supported these findings, since in general, tensile strength, modulus with modified montmorillonite were higher than the corresponding properties of the composites with unmodified montmorillonite. Adding organically modified clay improved the tensile strength of unsaturated polyester by $22\%$ and the tensile modulus of unsaturated polyester was also improved by $34\%$.

  • It is known that cement production not only consumes large amount of energy but also contributes substantially to the green house gas emission. Therefore, there is a demand to develope a new technology to produce energy efficient and environmental conscious cements. The most recent, wood wool ceramic board is being applied in various building material field, for example thermal insulating and acoustic absorption material. This paper focused on improvement of the physical properties for wood wool ceramic board applied inorganic polymer binder. As the result of this experiment, what we could obtain better wood wool ceramic board's properties such as density, water contests, water resistance and band strength, was 0.46, $10{\sim}12%$, 1.9% and $40kgf/cm^2$. This result can be applicable to commercial wood wool ceramic board.
