Deterioration of concrete

Deterioration of concrete

A detailed explanation of the causes of concrete deterioration! *Agents wanted!*

The main causes of "concrete deterioration" are the presence of capillaries (porous bodies) and the existence of pore solutions. Deterioration factors such as moisture, carbon dioxide, and chloride ions in the atmosphere infiltrate through capillaries and, using pore solutions as a medium, undergo chemical reactions and diffusion. It is important to densify the capillaries and reduce the pore solutions. In particular, pores larger than 50 nm (macro-pores) are said to be problematic as they allow for easier infiltration of deterioration factors. By applying our "Inner Coat" and "RCG Inner Silica," we can transform these macro-pores into harmless pores, thereby suppressing the infiltration of deterioration factors. *For more details, please refer to the external link page or feel free to contact us.

Test results of the inner coat (formerly known as RC inner seal)

Test results of the inner coat (formerly known as RC inner seal)

Introducing the test results of the inner coat (formerly known as RC inner seal)!

We would like to introduce the test results of "Inner Coat" from RCG Japan Co., Ltd. In the "Water Permeability Test" conducted at the Building Materials Testing Center, the suppression of water infiltration (waterproofing) was measured. By applying the Inner Coat, a reactive gel is formed, reducing the pore diameter, which prevents water permeability into the interior and demonstrates waterproofing effectiveness. Additionally, tests were conducted to verify the suppression of initial drying shrinkage cracks, salt damage, and freeze-thaw effects. 【Conducted Tests】 ■ Water Permeability Test ■ Average Chloride Ion Penetration Depth Test ■ Freeze-Thaw Test ■ Accelerated Carbonation Test ■ Friction Test *For more details, please refer to the external link page or feel free to contact us. The catalog for "Inner Coat" is also available for download in PDF format.

Features of LIQUID GUARD

Features of LIQUID GUARD

A finishing agent that preserves the texture of building materials while suppressing dirt and mold!

We would like to introduce the features of "LIQUID GUARD" that we handle. Instead of coating with a film, it penetrates into the substrate, and the main components (fluorine, silicone) chemically bond with the capillaries and voids to form a highly durable water-repellent layer. Unlike products aimed at surface water repellency like water repellents, it forms a penetrating layer within the material, densifying the capillaries and voids of the building material, significantly reducing water absorption. Therefore, as long as the coated surface is not worn away, the effects of deterioration prevention and dirt resistance will persist. 【Features】 ■ Does not change the appearance of the material ■ High durability protection ■ Efflorescence prevention effect *For more details, please download the PDF or feel free to contact us.

Causes of construction material troubles

Causes of construction material troubles

By suppressing water absorption, aesthetic appeal and degradation protection can be maintained!

The "LIQUID GUARD" that we handle is a penetrating water-repellent agent that protects building materials from various troubles. Most building materials are water-absorbent. If there is no water absorption rate, moisture uptake, efflorescence, surface stains, and rust will not occur. Due to their water-absorbent nature, building materials can become contaminated. By suppressing water absorption, aesthetic appeal and deterioration protection can be maintained. 【Features of LIQUID GUARD】 ■ Does not change the appearance of the material ■ High durability protection ■ Efflorescence prevention effect *For more details, please download the PDF or feel free to contact us.
