Dual-Sample Free Calcium Oxide Measurement System Twin-Specimen Unbound CaO Determination Tester Dissociative Lime Test Machine
Application Scope
Fully automated measurement of free calcium oxide (f-CaO) in cement raw meal, clinker, and finished cement products.
Dual-Sample Free Calcium Oxide Measurement System Twin-Specimen Unbound CaO Determination Tester Dissociative Lime Test Machine
Development Background
Free calcium oxide (f-CaO) directly affects cement soundness. Therefore, measuring the f-CaO content in raw meal, clinker, and finished products is essential to ensure the cement meets quality standards.
Dual-Sample Free Calcium Oxide Measurement System Twin-Specimen Unbound CaO Determination Tester Dissociative Lime Test Machine
Standards Compliance
This instrument is designed based on the "Ethylene Glycol Method" for determining free calcium oxide as specified in the national standard *GB/T 176-2017: Methods for Chemical Analysis of Cement*.
Dual-Sample Free Calcium Oxide Measurement System Twin-Specimen Unbound CaO Determination Tester Dissociative Lime Test Machine
Traditional Methods
Cement plants and laboratories currently use semi-automated free calcium oxide analyzers.
Drawbacks of semi-automated analyzers:
Only the heating and stirring processes are automated; timing and titration require manual intervention by the analyst;
Operations are cumbersome; the analyst must be present throughout the test, failing to save on labor costs;
The titration endpoint is determined visually, making results susceptible to subjective judgment.
Dual-Sample Free Calcium Oxide Measurement System Twin-Specimen Unbound CaO Determination Tester Dissociative Lime Test Machine
Product Advantages
Fully compliant with the national standard *GB/T 176-2017: Methods for Chemical Analysis of Cement*;
Fully automated testing; no manual monitoring required;
Capable of measuring two samples simultaneously;
Measurement modes include both "Rapid" and "Standard" settings;
Fully automated color detection;
