Sidhya® Grout Fluid 735
Set retarding & stabilizing admixture for cement suspensions
Description
Sidhya® Grout Fluid 735 is a special retarder developed to control the hydration of tunnel grouting systems. The product is a high-performance admixture for greater workability and extended open time of Annular Gap Grout used for back filling. The product’s special formulation also has a stabilizing effect which makes the grout more pumpable and easy to store in TBM. The application of Sidhya® Grout Fluid 735 enables increasing the compressive, tensile and flexural strength of annular grout mixes.
Applications
Sidhya® Grout Fluid 735 is a high-performance super retarder designed for extending the hydration process of cementitious suspension and concrete. Aside from extending the initial and final set times and enhance the strength through cement particle dispersion. The product can be mainly used for the following applications:
- Production of high-quality back filling grout in tunneling.
- Production of high extended open time grout up to 96 hours.
- Production of high-quality grout in Gravity dam construction.
- Can be used as a retarder in long haul concrete in Dams.
- Production of hot weather concrete & grouting.
- Ideal for large pours such as dams and raft foundations.
- Helps in avoiding cold joints while pouring.
Mixing
Sidhya® Grout Fluid 735 is not recommended to be added along with dry aggregates and cementitious materials. Sidhya® Grout Fluid 735 should be added to the mixer post addition of full water, cementitious and other additives. To achieve the optimum performance, the product is recommended to have minimum wet mixing period of 60 seconds depending on the mixing conditions.

Advantages
Sidhya® Grout Fluid 735 improves the workability and open time of concrete and grout and hence provides the following advantages:
- Reduces the risk of pumping and choking of Back fill grout in TBMs.
- Stabilizes and controls the hydration time of annular gap grout in TBMs.
- Easy management of grout supply chain on Tunnel boring machines.
- Increases production efficiency of long-haul concrete.
- Enhances the performance of drilling fluids in gravity dam.
- Improves the elastics and compressive strength of grout.
- Improvement in placement of concrete.
- Reduces shrinkage and creep.
Dosage
The recommended dosage of Sidhya® Grout Fluid 735 should be between 0.2% to 2.0% by weight of cementitious. Effects of over dosage can delay the setting time and lead to bleeding and segregation in fresh properties.
The optimum dosage of the Sidhya® Grout Fluid 735 should be determined by preliminary trials at site. The dosages above recommendations can be used if agreed by the client and consultant for special applications along with consultation of Sidhya® technical team.
Compatibility
Sidhya® Grout Fluid 735 is compatible with all types of cement and binders such as GGBS, Ultra Fine GGBS, Micro silica, Fly ash and Metakaolin. Sidhya® Grout Fluid 735 when using along with other Sidhya® products should be added separately and must not be blended prior to addition.
Important: It is important to conduct preliminary trials when using more than one admixture. In the TBMs application we recommend the setting time can be controlled with modified accelerators such as our Sidhya ® Quick Set AGG.
Technical Compliances
Sidhya® Grout Fluid 735 conforms to the requirements of IS 9103: 2007, EN 934 -2, ASTM C494 for Type B retarding admixtures.
