APPARATUS FOR REACTIVITY OF QUICKLIME AZA0809
The AZA0809 Quicklime Reactivity Apparatus is a precision laboratory instrument engineered to measure the thermal reactivity of quicklime (CaO) when it reacts with water—a process known as slaking. This exothermic reaction produces heat, and by recording the temperature rise over time, the apparatus helps determine the quality, fineness, and reactivity rate of quicklime.
Widely used in lime processing plants, cement industries, construction materials testing labs, and research institutions, this apparatus ensures accurate evaluation of quicklime performance for applications in soil stabilization, water treatment, chemical manufacturing, and cement additives.
The apparatus fully complies with IS 1514:1990 – Methods of Sampling and Test for Quicklime and Hydrated Lime and ASTM C110 – Standard Test Methods for Physical Testing of Quicklime, Hydrated Lime, and Limestone.
Description
How the Test Works
A known mass of quicklime is placed in a borosilicate reaction flask. A measured quantity of water is added, and the temperature is recorded at defined intervals.
The ∆T (temperature rise) indicates the quicklime’s reactivity level and suitability for industrial use.
