HIGHSTRENGTH STRUCTURAL LIGHTWEIGHT CONCRETE
One it mechanically reduces the water/cement ratio [w/cm] similar to a highrange waterreducing admixture. This technique can generally reduce water requirements of a concrete mix by 20% to 54% providing a similar increase in concrete strength. 0. 69 MPa [100 psi] increase in strength for each decrease in water/cement ratio w/cm]. The second technical feature is that it also performs as an

What is Silica Fume?
Concrete containing silica fume can have very high strength and can be very durable. Silica fume is available from suppliers of concrete admixtures and, when specified, is simply added during concrete production. Placing, finishing, and curing silicafume concrete require special attention on the part of the concrete contractor.

Superplasticizer Wikipedia
Superplasticizers, also known as high range water reducers, are chemical admixtures used where welldispersed particle suspension is required. These polymers are used as dispersants to avoid particle segregation (gravel, coarse and fine sands), and to improve the flow characteristics (rheology) of suspensions such as in concrete applications.
