CR | Raphahcon

 Features

1. The product is highly strong, causes little cracking, and has high workability 

   because it is a one ingredient-type mortar that can be used after being mixed 

   with just water. 

2. It is economical due to its low rebound rate of 5% and is highly durable 

   because it is an inorganic mortar like concrete.  

3. The product is highly adhesive, anti-rust, neutralization-resistant, 

   chemical-resistant and chlorine ion penetration-resistant.

 Uses

For recovering sections of various concrete structures requiring high-strength 

compressive strength, such as civil engineering structures, building structures, 

maritime structures and special structures  

 A property of 

 matter

 One ingredient-type inorganic gray polymer mortar powder

 Instructions

  It is possible to do hand plastering and spraying (mechanization).

1. For over 5cm repair, if bending and tensile strength reinforcement are necessary, 

   place reinforcing rods, wire meshes, etc. and then proceed to the next process.

2. Put the correct amount of water (clean fresh water) into the mixer in the weight 

   rate of Raphahcon : water = 100 : 15~18 and mix them for three minutes or more 

   while slowly putting in Raphahcon.  (if there is no mixer, use a hand drill mixer)

3. After mixing, place the product immediately on the construction surface using 

   a trowel or sprayer. 

4. For raising the thickness, do spraying and plastering with 0.5-1cm during the 

   first placing, 2-5cm during the second and third placing, and finish with 

   0.5-1cm during the final placing.  

   (Good adhesion and plastering can be gotten through doing primer/main 

   placing thinly and re-placing thickly.)

5. In direct sunlight or during summer, cover it with curing cloth or spray the 

   curing agent immediately after placing.

6. The lowest construction temperature shall be 5℃, and the smallest 

   construction thickness shall be 5mm.

 Cautions

1. Until the applied parts get dried, they shall be protected from rain or snow. 

2. While working, be sure to wear protective equipment, such as masks, 

  goggles and gloves.  

3. Be careful about curing at temperatures of 5℃ or lower.

 Packaging

 25 kg/bag. The product can be stored in dry places for six months
