Uses cebex 100 is an admixture for cementitious grouts where a reduced water/cement ratio and positive expansions are required. Applications include duct grouting, Bed grouting, Non, Shrink infilling and jointing. Gains from gaseous expansion system compensates for plastic shrinkage and settlement in the properly designed cementitious grout. Reduced water/cement ratio mixes in the grout mix ensures low permeability and long, Term durability in service. Gives grout high fluidity with low water/cement ratio, Thus making placement or injection of the grout easy. Lacking any iron metal content to corrode and cause staining or deterioration due to rust expansion in the grout. Composition allows superior strength at early stages development without the, In grouts utilization of chlorides. Description cebex 100, A plasticised admixture designed for grout expansion is delivered as a powder. The composition consists of an amalgamation 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. Application it shall be ensured that areas to be grouted are clean, Sound, And then pre, Wetted. The unrestrained surface area of the grout must be kept to a minimum. The grout shall be placed within 20 minutes of mixing to gain the full benefit of the expansion process. Usual placing or pumping procedures shall be adopted ensuring a continuous operation.
