Betonex is supplied as a powder admixture. The material is a combination of a plasticizing agent and a gas producing expansion medium. The plasticizing agent allows the use of a reduced water/ cement ratio with consequent increased strengths and durability. The expansive medium counteracts the natural settlement and plastic shrinkage of the grout and aids stability and cohesion. Sufficient restrained expansion is developed to ensure a high degree of interfacial contact

Gaseous expansion system compensates for plastic shrinkage and settlement in properly designed cementitious grout
 Reduced water/cement ratio mixes in the grout mix ensures low permeability and long term durability in service
 Gives high grout fluidity with low water/cement ratio, thus making placement or injection of the grout easy
 No metallic iron content to corrode and cause staining or deterioration due to rust expansion in the grout
 Composition allows high early strength development in grouts, without the use of chlorides

Betonex is an admixture for cementitious grouts where a reduced water/cement ratio and positive expansion is required Applications include bed grouting, duct grouting, non-shrink infilling and jointing

The optimum dosage of Betonex to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is 0.5 Kg/100 kg of cementitious material to achieve expansion up to 4%
