Both YJ-51YYLX and YJ-K308 are built around ordinary 42.5 \/ 52.5 Portland cement. You keep buying the cement you already buy.<\/p><\/details>\n      <details><summary>How do you decide the dose rate?<\/summary><p>Higher dose means faster set and higher early strength. For YJ-51YYLX the working range is 8\u201325% by weight of cement. Where you sit in that range depends on your target demould time and your workshop temperature, which is what the lab trial establishes.<\/p><\/details>\n      <details><summary>Will fast early strength cost me late-age strength?<\/summary><p>Not with this chemistry. It co-hydrates with the cement system, so early strength builds fast and late strength continues to rise. That is the main difference from a sulphoaluminate cement system.<\/p><\/details>\n      <details><summary>What sample quantity can I get?<\/summary><p>25 kg, which is enough to run a proper plant trial rather than just a laboratory curiosity.<\/p><\/details>\n      <details><summary>Do you support OEM or private label?<\/summary><p>Yes \u2014your bag and your brand, our formulation.
