氟石膏粉煤灰胶结材的研究

凝材料既可在空气中，也可在水中凝结硬化，具有较好的胶凝性能与体积稳定性。氟石膏粉煤灰胶结材可用于制造新型墙体制品，也可作为微膨胀剂配制高抗渗性混凝土。

A new binder is prepared with fluorgypsum and fly ash which both are industrial waste residue.Adding appropriate quantity of cement as excitant,this binder can hydrate and harden both in air and in water.It presents satisfactory cementitious performance and high volume stability.This binder can be used to produce novel building products or as expansion agent to prepare very low permeable concrete.
