AD-TEK WR-CE is a cost-effective lignosulphonate-based water-reducing admixture designed to produce concrete with extended slump life and water reduction. It is used to produce a good quality concrete, where water reduction with easy placing and working are needed. Ad-Tek WR-CE is designed to meet RTA requirements. PRODUCT INFORMATION BULLETIN
Ducon water reducing admixtures, the name itself defining that they are used to minimize the water demand in a concrete mix. Workability is the important property of concrete which is improved with the addition of water but if water is added more than required the strength and durability properties of concrete gets affected.
Workability is required for good quality concrete. So, water content and workability should be balanced. Water content shouldn’t be less in mix-design. The purpose of mix-design is to produce most economical concrete product with desired strength. And that is done by tweaking the above rules. If required, chemical admixture can be mixed with ...
