According to the standard EN1504, issues related to the restoration of concrete structures are divided into several sections, the most important of which are periodic repairs, structural maintenance instructions and restoration of damaged concrete parts due to operating conditions.

Epoxy based concrete repair

However, it is necessary to mention that in addition to increasing the level of design, implementation and supervision standards in construction projects and improving the quality of concrete construction, execution and processing conditions, some structures still need repair operations during or after construction. According to this standard, the use of materials in the non-structural category (R1 and R2) is usually limited to the elimination of surface defects, surface preparation as well as items related to the appearance of the work. Due to the applications mentioned in the design of this category of repair materials, features such as adhesion, appearance and durability are preferred to items such as mechanical resistors.

 

In this type of restoration, the use of cement repairers is usually recommended. Because epoxy-based repair materials, unlike cementitious materials, due to the difference in the coefficient of thermal expansion with concrete, if used in large volumes or thickness, they will face cracks or separation. Therefore, if the cement-based repair materials meet the requirements of mechanical strength and adhesion in the structure, it has a higher priority for repairing concrete sections.

 

This ready-made mortar with its soft texture and ductility provides the possibility of suitable troweling and easy polishing, and due to the various polymers used in its construction, it has significant adhesion to the following sections. Concrete repairer Due to its advantages such as high adhesion to various materials, no shrinkage, resistance to melting and freezing cycles, being the same color with concrete, as well as ease of implementation can be used in all projects. In addition, the use of this material for public use will reduce the cost of repair in the project.

 

This material is mainly recommended for general and internal uses of the building or indoor space, such as floor and wall substructures before installing various decorative materials. Other uses for this material include filling non-structural joints and cracks, intermediate cavities, and muscle contraction.

 

This material is used to repair porous surfaces, repair fractures of concrete or cemented sections, fill concrete roughness and level the roughness caused by error in formwork. Compared to other mortars and repair materials, concrete repairer in terms of cost of labor , Quality and ease of implementation are in good condition.

Mechanism of concrete restorative effect

Granulation of ready-made concrete repair mortar is very soft and fine-grained and selected from micronized silica, and therefore has a trowel and good dispersion properties, and due to the high percentage of cement and copolymer resin, high adhesion to the substrate. has it . This material is resistant to the penetration of liquids and corrosive substances after application and is therefore a suitable mortar to repair the damage of the desired surfaces for sealing. The presence of polypropylene fibers in the restorative structure of concrete will increase the mechanical strength of the restorative mortar as well as its reinforcement.

E.M.REPAIR concrete repair method

The surface should be clean, firm and free of grease, dust, paint, oil and loose particles.
Depending on the required efficiency and thickness of the implementation, it is recommended to add about 5 to 5.5 liters of water to each 25 kg bag. Mixing the powder with water should be done using an electric mixer (drill + blade). The bucket or container in which the powder and water are mixed should be proportional to the speed of work and the volume of mixing. Always add the powder slowly to the water and note that when the powder is added to the water, the electric mixer should be on and the mixing process should continue until a uniform and homogeneous mixture is obtained.
Be sure to moisten the surfaces under E. M. REPAIR before applying the prepared mixture.
Apply the prepared mortar with a trowel or spatula on wet surfaces.
Dosage

Depending on the amount of porosity and unevenness of the applied surfaces, about 1.5 to 2.5 kg of E. M. REPAIR is required to cover one square meter with a thickness of 1 mm.

Attention

Always mix the amount of powder with water to be used in less than 20 minutes at most.
After the applied mortar is half dry, keep all surfaces moist by spraying water for at least 24 hours.

آماده سازی بستر ترمیم کننده های بتن :

 

سطح مورد نظرباید تمیز و فاقد هرگونه مواد آلاینده بوده و همینطور می بایستی نقاط سست و ضعیف بتنی را مشخص کرد و نسبت به تخریب آن ها اقدام نمود. این مناطق تا عمق 10 سانتیمتری بریده شده و دقت شود تا جای ممکن شکل تیزگوشه و مربعی داشته باشند.

 

همچنین حداقل ضخامت 10 میلیمتری پیرامون منطقه تعمیر شده حفظ شود. سطح مورد نظر باید خدشه دار باشد و دست کم از ناهمواری های 5 میلیمتری با فواصل 20 میلیمتری برخوردار باشد. چنانچه با سطوح آلوده و سست برخورد شود بهتر است مراتب اجرایی با سرپرست کارگاه هماهنگ شود تا نسبت به تمیز کاری و برشکاری احتمالی اقدام گردد.



در صورت مشاهده آرماتور های رنگ زده ابتدا از سلامت درونی آن اطمینان یافته سپس نسبت به زنگ زدایی توسط یکی از روش های برس زنی یا ماسه پاشی اقدام نمایی تا سطح فولاد تمیز نمایان گردد.
محافظت مضاعف آرماتورها توسط پوشش های مخصوص مقدور خواهد بود. در مواردی که آرماتور ها دچار خوردگی وسیع باشند بایستی نسبت به تعویض آنها اقدام نمود.

بسته به مقدار تخلخل و ناهمواری ایجاد شده بر روی سطوح مورد اجرا، برای پوشش یـک متر مربع به ضخامت 1 میلی متر حدود 5/1 تا 5/2 کیلوگرم E. M. REPAIR مورد نیاز می باشد.

توجه

  • هميشه آن مقدار پودر را با آب مخلوط کنید كه حداكثر در مدت زمان كمتر از 20 دقيقه مورد استفاده قرار گيرد.
  • پس از نیمه خشک شدن ملات اجرا شده، تمامی سطوح را حداقل 24 ساعت با اسپری کردن آب مرطوب نگه دارید.
  • چسبندگي زیاد به انواع مصالح
  • بدون انقباض
  • مقاوم در مقابل سيكل هاي ذوب و يخبندان
  • همرنگ با بتن
  • سهولت اختلاط و اجرا

 

 

  • تسطیح و ترمیم سطوح متخلخل
  • ترمیم ترک خوردگی ها و شکستگی های مقاطع بتنی یا سیمانکاری شده
  • پر نمودن ناهمواری هاي بتن و حفره های باقی مانده از ميان بولت ها
  • تسطیح ناهمواری های ناشی از خطا در قالب بندی
  • زيرسازي كف و دیوارها قبل از نصب انواع مصالح دکوراتیو

 

دانه بندی ملات آماده ترمیم کننده بتن ، بسیار نرم و ریز دانه و از سیلیس های میکرونیزه انتخاب شده می باشد و به همین خاطر خاصیت ماله خوری و پخش شدن متناسبی دارد و به لحاظ وجود درصد بالایی سیمان و رزین کوپلیمر، خاصیت چسبندگی بالایی به سطوح زیرآیند دارد .

 

 این ماده بعد از اجرا در مورد نفوذ مایعات و مواد خورنده مقاوم می باشد و به این علت ملات متناسبی برای ترمیم خرابی های سطوح مورد نظر برای آب بندی می باشد. وجود الیاف پلی پروپیلن نیز در ساختار ترمیم کننده بتن ، باعث افزایش مقاومت های مکانیکی ملات ترمیمی و همچنین مسلح شدن آن خواهد شد .

 

 لازم به ذکر است ، استفاده از ملات های تعمیراتی اپوکسی بر روی سطوح سیمانی و بتنی به لحاظ تفاوت در ضریب انبساط حرارتی ، برای ترمیم سطوح بتنی یا سیمانی با عمق خرابی زیاد مناسب نمی باشد چون در صورت به کارگیری مواد ترمیمی اپوکسی، در ضخامت و حجم های بالا شاهد ترک خوردگی و جدا شدگی خواهیم بود و لازم است توسط محصولی که از نظر ساختار شباهت زیادی به بتن داشته باشد ، عملیات ترمیم صورت گیرد.

 

مدت نگهداری: یک سال در بسته بندی اولیه

شرایط نگهداری: دور از رطوبت و تابش مستقیم نور خورشید

بهترین دمای نگهداری: 10+ تا 30+ درجه سانتیگراد
