Accelerator is a kind of additive to regulate setting time and hardening speed of concrete or mortar, of which many products are available. 速凝剂是调节混凝土(或砂浆)凝结时间和硬化速度的外加剂,品种较多。
The authors discussed the effect of the set accelerator ( NH4H2PO4) on the hydration and hardening of α-Ca ( PO4) 2 ( ie α-TCP), and tested the setting time and mechanical strength of the appropriate hardening products. 讨论了不同浓度NH4H2PO4促凝剂对α-Ca3(PO4)2(α-TCP)水化和硬化的影响,测试了相应的硬化物凝固时间和机械强度。
