Conbextra Chemical is used for free flow precision grouting in a wide range of applications
These critical uses include heavy duty support beneath machine base plates, bridge bearings and crane rails
Unique non-metallic dual expansion system compensates for shrinkage in both the plastic and hardened states.
Excellent initial flow and flow retention
High early strength facilitates rapid installation and early operation of plant
Hydrogen free gaseous expansion
Suitable for pumping or pouring over a large range of application consistencies and temperatures
Conbextra Chemical conforms fully to U S Corps of Engineers specification for non-shrink grout CRD-C621-89 and ASTM C1107-91 (Type C)
Conbextra Chemical is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free-flowing precision grout for gap thickness up to 125mm
In addition the low water requirement ensures high early strength and long term durability
Conbextra Chemical is a blend of port land cements, graded fillers and chemical additives which impart controlled expansion in both the plastic and hardened states. The filler grading minimizes segregation and bleeding over a wide range of application consistencies

Conbextra Chemical is used for grouting of equipment like blast furnace, chimneys, etc., and also for concrete floor refurbishments, where high temperature and thermal gradients are envisaged
Expansion system compensates for shrinkage in the plastic state
No iron content to cause staining
Prepacked material overcomes onsite batching variations
Develops high strength
Free flow ensures high level of contact with the load bearing area
Thermal resistance property ensures effective functioning even at high temperatures up-to 5000C and thermal gradients
Conbextra Chemical is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free flowing, non shrink grout for applications in high temperature zones
Conbextra Chemical is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion, while minimizing water demand. The product is designed to provide resistance to high temperatures upto 5000C without losing its performance characteristics
An experienced technical advisory team is available to give technical service on request.
Chloride free: Composition allows high early strength development without the use of chlorides
Conbextra Chemical is tested using the appropriate sections of the following specifications: BS 188, BS 4550 & BS455
Conbextra Chemical is supplied as a ready to use dry powder requiring only the addition of water to produce a free flowing, non shrink, grout material which exhibits exceptional resistance to 'washing out' of the cement phase when placed in stationary or moving water
The material is a mixture of specially processed cement, with carefully graded fine aggregate
Additives impart controlled expansion, water reduction and non washout characteristics
The aggregate grading is designed to aid uniform mixing, minimize segregation and bleeding whilst assisting the flow characteristics.
