ڤيتوجراوت سي جي 518

ترويبة أسمنتية غير قابل للانكماش غير معدنية.

<p>Vetogrout CG518 is a single-component, cementitious, structural, and non-shrink grout that is ready to use and requires only the addition of water on site. Once mixed, the product can be applied by pouring it into prepared form-work to make demanding structural repairs (It is compatible with most host concrete types). Vetogrout CG518 is composed of a blend of hydraulic cement, carefully selected &amp; graded aggregates, fibers, and special additives to give it its unique properties.</p>

Uses

  • To grout precast panels & wall / base segments.
  • To repair broken structural concrete elements (in large segments). 
  • To cast structural members & elements (where conventional grouts can not perform). 
  • For base plate grouting (where sections are thicker than 25 mm).

Advantages

  • Factory-controlled pre-blend ensures consistently high quality. 
  • Designed for large thickness grouting & repair work. 
  • Requires only the addition of water on-site at the time of use. 
  • Compatible with normal concrete. 
  • High freeze-thaw resistance. 
  • Low porosity & Non-shrink characteristics. 
  • High bond strength. 
  • Cost-effective.

Usage Instructions

The surface should be sound, clean, & free from loose material, grease, laitance, dirt-curing compounds, etc. 

Wet the substrate to achieve a saturated and dry surface condition before the application of Vetogrout CG518. 

Erect the hopper system and a form-work, make sure that the shuttering is watertight using a polyurethane sealant (such as Vetoflex PU780) or using a rubber gasket seal. This step ensures no leakage of cement paste & water from the shuttering. Contact Saveto’s local representative for more technical information, Saveto’s grouting detailed method statement, and CAD details. 

The base plate must be clean and free from oil, grease, or scale. Air pressure relief holes should be provided to allow venting of any isolated high spots. If leveling shims are used and removed after the grout has hardened, they should be treated with a thin layer of grease.

Generally, the gap width between the perimeter formwork and the plate edge should not exceed 150 mm on the pouring side, and 50 mm on the opposite side. It’s recommended to not have a gap at the flank sides.

For best results, use a mechanically powered grout mixer. When using quantities up to 50 kg, a slow-speed drill fitted with a high shear mixer is ideal. Larger quantities will require a high-shear vane mixer (Do not use a colloidal impeller mixer). 

To enable a continuous grouting operation, it is essential to provide sufficient mixing capacity and labor. It may require the use of a grout holding tank (it’s essential to to agitate the grout gently). 

Add water at a percentage of 11-13.5% of the weight of the grout (This should be accurately measured into the mixer). 

Slowly add the entire content of the Vetogrout CG518 bag then mix continuously for 5 minutes. This will ensure that the grout has a smooth, even consistency.

Place the grout within 20 minutes of mixing to gain the full benefit of the expansion process. Place Vetogrout CG518 at a thickness up to 100 mm in a single pour (When used as an under-plate grout). 

For thicker sections, it is necessary to fill out Vetogrout CG518 with 30 - 50% of the well-graded & silt-free aggregate -depending on the thickness- to minimize heat build-up (typically 10 mm aggregate is enough). 

Any bolt pockets must be grouted before grouting between the substrate & the base plate. (Continuous grout flow is essential). Prepare a sufficient amount of grout before starting & regulate the time taken to pour a batch to the time to prepare the next one. The repair area should not exceed 2.5 m2 in a single application.

When the grouting process is complete, cover exposed areas well with polyethylene sheets to prevent evaporation of the water in the mix for the first 24 hours; later, the grouted area should be cured using clean potable water twice a day for 3 days. Or you can use the Vetocure XT425 (a water-based curing compound after placing the grout).

Remove Vetogrout CG518 from tools and equipment with clean water immediately after use. Remove cured material mechanically.
