Abstract (AI)
The investigation results of changes in cement grout observed during the induction and post-induction periods of hardening while adding fine-grinded glass additives are presented.It is assumed that glass introduction decreases pH of the system due to the chemical interaction with alkaline medium of the cement grout.The obtained results are important for the solving of the problem of glass wastes usage in the cement technology.
Key Findings
1
Fine-ground glass additives alter cement grout behavior during both the induction and post-induction periods of Portland cement hardening.
2
The findings are relevant to utilizing glass waste in cement technology.
3
The study assumes that introducing glass lowers the cement-grout pH through chemical interaction with the alkaline medium.
