Abstract

Tests have been done to study the compound mineral admixtures of lithium-salt industrial residue (LSR) and fly ash. The results indicate that the addition of LSR plays a significant influence on both pozzolanic activity and strength of concrete at ages of 7d, 28 d, and 60 d respectively. An optimum dosage of LSR is identified in the compound admixtures. It is of certain practical value to the study and application of the high compound admixtures content and high fly ash content concrete.
