Abstract：

This　study　investigates　the　changes　of　tannic　acid　(TA)　at　varying　concentrations　in　cement　pore　solution.　Interestingly,　TA　spontaneously　forms　nanosheet　tannic　acid-calcium　polymeric　networks　(TA-Ca)　by　interacting　with　Ca2+.　Spectral,　thermal,　ionic　and　organic　carbon　analyses　determine　the　composition　and　structural　characteristics　of　these　networks　and　detail　the　formation　mechanism.　The　networks　are　connected　via　hydrogen　bonding,　C–C　coupling　and　complexation.　Moreover,　network　composition,　structure　and　formation　are　closely　dependent　on　TA　concentration.　At　low　concentrations,　crystalline　coordination　polymer　networks　form,　following　second-order　kinetics　(key　factor:　Ca2+　concentration).　At　high　concentrations,　amorphous　C–C　coupled　polymer　networks　form,　following　first-order　kinetics　(key　factor:　catalytic　oxidation　of　Ca2+).　This　study　aims　to　elucidate　the　reaction　and　mechanism　of　TA　in　cement　paste,　providing　a　novel　theoretical　basis　for　applying　renewable　bio-admixtures　in　sustainable　construction.　©　2023　Elsevier　Ltd
