Testing Machines and Instruments for Cement
Cement
Cement is a very old binder that was already used by the Romans over 2000 years ago. The main raw materials for the production of cement are limestone, clay, sand and iron ore, which are burned in a rotary kiln and form cement clinker as a result of chemical reactions. The cement clinker is finely ground and with the addition of gypsum, modern Portland cement is produced.
Cement in combination with water and other various aggregates is the basis for mortar and concrete. The ratio between these substances determines the subsequent properties such as strength, durability and elasticity. Various standards have been established around the world to ensure the quality of the final product through various tests at different stages of the production process. The most common standards for determining strength are EN 196 and ASTM C-109.

Testing Instruments
Free Lime Analyzer ToniLIME
The analyzer TonLIME is designed to determine the content of free, uncombined lime in cement and cement clinker.
The operating principle is based on the measurement of the electric conductivity in a solution consisting of cement and hot glycol in comparison with a stored calibration curve.
