To further understand the influence of HPMC on cement-based material (CBM) hydration, this study investigates hydration characteristics and early product formation C3S-gypsum binary pastes with HPMC. Results demonstrated that significantly delayed heat release peak occurrence, most pronounced effect induction period duration, which was increased by 1-2 times adding Calculations employing Krstulovic-Dabic kinetic model show extended nucleation crystal growth (NG) stage, increasing duration 21% in 0.05% group. Additionally, 0.035% group showed a 2.6% decrease CSH gel 14% Ca(OH)2 generation after 1 day, while also reducing chemically bound water (CBW) content 20%, CBW relative variations correlating stage rate constants. This confirms delays reduces generation, aiding future regulation CBM processes.
