BUSTAN ADDMIX

Addmixtures are normally provided as water based solutions and can be added to the concrete at up to 5% on cement weight, although most types are added at less than 2% and many are at less than 0.8%. Detailed information on admixture types is available from the industry professional body. Admixtures which, without effecting the consistence, permits a reduction in the water content of a given concrete mix, or which, without affecting the water content increases the slump/flow or produces both effects simultaneously. This application of admixtures improves the dispersion of cement particles resulting in an increase in workability. With a typical dosage from 0.2-5.0 % by weight of cement, depending on the type of admixture application, generally plasticizers increase the workability at a given water/cement-ratio by between 50 and 100 mm slump with no loss of strength or durability. Alternatively, they can be used to reduces water content in a range of 5 -12%. This reduction in the water/cement ratio gives significant durability enhancement and strength increase for constant cement content. Use of Admixtures by the ready-mix concrete producers help to optimize the cost effectiveness of the mix. Shelf life: 12 months in unopened original packing, if stored properly. Packing � 20 LTR.
