Preparation of Butyl Acrylate Copolymer Emulsion and Its Regulation Effect on Cement Hydration.Due to its large volume and poor thermal conductivity, mass concrete is prone to temperature cracking caused by heat release during cement hydration after pouring.  The inhibitory mechanism of a PBA emulsion on cement hydration was analyzed by characterization techniques such as isothermal calorimetry, X-ray diffraction Rietveld full-profile fitting method (XRD), thermogravimetric-differential scanning calorimetry (TG-DSC), and mercury intrusion porosimetry (MIP).
