Superplasticizer Addition to Carbon Fly Ash Geopolymers

Mortar samples were prepared with the same molar ratio of Na 2 O/SiO 2 previously used for geopolymers. SMF, PCE, ACRa, and ACRb were tested as superplasticizers in the amount of 0.6 wt. %, with the only exception of PCE, which was also tested in the amount of 1.0 wt. %. A geopolymer mortar without SP was realized as a reference.

was that for mortar containing the superplasticizer additive at 00C compared with reference mortar mix. For reference mortar mix M1 at (28) days, the residual compressive strengths are about (41 N/mm 2, 40 N/mm) at a temperature of (200, 400)0C respectively. The residual stresses for mortar containing additives are about (33 N/mm2, 32

Superplasticizers and Air| Concrete Construction Magazine

In Eastern Washington across eight-plus concrete plants and many aggregate sources we do see air spikes from the addition of superplasticizer. Going from a mix without superplasticizer to an identical mix containing superplasticizer we typically have to reduce the air entraining admixture content by 50% to maintain the same air content.

SuperPlasticizers | High Range Water Reducers.Types, Uses

The workability of concrete can be increased by adding superplasticizers without adding very much water. The mechanism and properties of superplasticizers are very similar to plasticizers. Researches state that the water content of concrete can be reduced from 15 to 30% without reducing the workability of concrete.
