The effectiveness of different superplasticizers in ambient

1/3/2019 · The effectiveness of different admixtures in Na 2 SiO 3-Anhydrous one-part AAMs was evaluated. The most effective types for Na 2 SiO 3 AAMs were naphthalene when w/b ≤ 0.36 and polycarboxylate when w/b ≥ 0.36.

A series of polycarboxylate superplasticizer (PCE) polymers were synthesized from acrylic acid (AA) and isoprenyloxy polyethylene glycol ether (IPEG) at the mole ratios of 3.0, 4.2, 5.0 and 6.0. In this study, the molecular weight properties of PCE polymers were SUPERPLASTICIZERSEffectiveness of superplasticizers is measured by the time taken by a fixed quantity of cement paste and particular content of superplasticizers to flow through a standard funnel, known as Marsh flow cone (Figure 4).
