Admixtures for special applications
Flowric T
Concrete super retardant
[Suitable for heat-weather admixtures (added separately)]
FLOWRIC T adheres to the surface of various mineral binders such as cement, fly ash, and ground granulated blast furnace slag, and temporarily suppresses the contact between the particles and water. , is an admixture that delays the setting of concrete, and has the property that the setting time can be adjusted freely and easily within 3 days after mixing.
Features
FLOWRIC T is suitable for large concrete structures where cold joints are likely to occur, when continuous construction is required for integration, and for long construction such as the RCD construction method, which is a rationalization construction method for dam construction. Effective when processing time is required.By arbitrarily controlling the setting time of these concretes, it is possible to create durable structures without causing defects in overlapping parts.In addition, it facilitates the re-vibration construction of concrete, integrates the overlapping parts and facilitates the pile head processing of piles built on site, and is used for the erection method of structural columns in which columns are driven into cast-in-place concrete. is also valid.
How To Use
- ○ The setting delay property is greatly affected by the addition method and environmental temperature, so please decide the amount to be added by trial kneading.
- ○Combined use with AE water reducing agent and high-performance AE water reducing agent is common, and in the case of simultaneous addition, please measure as part of the unit water amount.
- ○ If you add it to the mixer truck at the site, etc., mix it at high speed for about 1 minute to disperse it evenly.
- ○The general range of additive amount is 0.2 to 1.0 (wt%) of the mass of the binder.
However, when used in combination with polycarboxylic acid-based high-performance AE water reducing agent, AE water reducing agent/high-performance type, a large amount of Flowric T is added (40% or more), especially in the high strength area of 0.5% or less water cement ratio. ), the fresh concrete may stiffen, so please check the freshness and setting retardation properties by trial kneading. - ○When using it together with an expansive agent for the purpose of suppressing temperature cracks in mass concrete, the expansion performance may be hindered due to the effect of delay in setting, so please perform trial kneading and check in advance.
