Gilsonite was first evaluated as a density-reducing additive for cementing slurries because of its low specific gravity () . Laboratory testing was set up to establish an optimum particle size for these applications with three primary points being considered: 1.
As a concrete additive, concrete water reducer plays a very important role in concrete applications. For example, the use of water reducing admixture can reduce the amount of water and increase the strength of concrete. Adding it can save cement consumption and reduce engineering costs.
Substances useful as water reducing and superplasticizer additives for cement compositions are formed by in situ polymerization of one or more ethylenically unsaturated acid monomers such as acrylic acid or maleic anhydride in a reaction medium comprising a polyether such as polypropylene glycol or a copolymer of ethylene oxide and propylene oxide to form a
Usage. In premixed and precast concrete elements to reduce the drying shrinkage of the concrete. In thin bonded topping slabs, to minimise the difference in shrinkage between the new topping and the existing substrate. In concrete elements which are restrained against shrinkage. For durable concrete in marine environments.
