Abstract

The article presents the results of study on effective ways to improve the strength of Low clinker slag Portland cement(LCSPC) with havinga clinker content of 5-19%with complex sulfate-alkaline and sulfate-alkaline-fluoride activation of slags. The increase of specific surface area of LCSPC led to a significant improvement of the strength and two stage grinding was very effective on increase of grain size of clinkers.The additionof additives such as sodium silicofluoride Na2SiF6, Fe2(SO4)3, and MgSO4were investigated and results show that Na2SiF6was effective to improve the strength.The influence of complex sulfate-fluoride and sulfate-fluoride-alkaline activation is investigated. The results obtained shown that a complex sulfate-fluoride-alkalineactivation of LCSPC increased significantly thestrengthof LCSPC by increasing the pH from 10 to 12-13.
