Temperature Cracking Mitigation Technology ND Retarder Method
This is a temperature cracking suppression technology using water and heat suppression type super delay agents.
The ND Retarder Method is a temperature crack suppression technology that improves construction workability and economic efficiency by using concrete with a super retarder "ND Retarder (NDR)" that has a hydration heat suppression effect added to the upper part of the base slab. Currently, there are seven achievements, including those planned for structures such as culverts and wall-type bridge piers, mainly in projects directly overseen by the Ministry of Land, Infrastructure, Transport and Tourism. 【Features】 ○ Use of hydration heat suppression type super retarder ○ Improvement and enhancement of workability and economic efficiency ○ Suppression of temperature cracking ○ Increased durability leading to longer lifespan ○ Control of setting time with super retarder For more details, please contact us or download the catalog.
