Specco W-42 SL plasticizer is a modified polycarboxylated high range water reducing admixtures formulated to produce self-compacting type (S.C.C.) concrete. W-42 SL plasticizer is specifically intended for use in precast and ready mix concrete providing high workability, slightly extended slump life, and improved fluidity with reduced or minimal vibration. The improved dispersing action of W-42 SL plasticizer results in concrete with “self placing” properties that surpass conventional superplasticizer benefits. Very low water to cement ratios can be obtained with as much as 25-30% total water reduction.
- Greater water reduction and lower dosage rates than traditional melamine or naphthalene based superplasticizers.
- Improved flow (self leveling) with self-healing rheology.
- High early strengths.
- Improved densification of surfaces.
- Reductions in vibration and manufacturing noise levels.
