Influence of Compounding Malic Acid with Plasticizers on Hydration Heat of α-Calcium Sulphate Hemihydrate
On condition of formulating malic acid (Malic) with super plasticizers (SPs), the hydration heat of α-calcium sulfate hemihydrate (α-HH) was studied. The results show that: Malic and SPs mainly adsorb on gypsum surface to exert inhibition; influence of compositing SPs on hydration process mainly depends on the adsorption of SPs and the effect of SPs on Malic adsorption; formulation of sulfonate melamine formaldehyde plasticizer (SMF) limits the adsorption of Malic.
