SLAKING VESSEL AZA0810
The AZA0810 Slaking Vessel is a specialized laboratory apparatus designed for conducting quicklime reactivity tests by monitoring the temperature rise during the slaking process. This evaluation is essential in cement, lime manufacturing, soil stabilization, and materials laboratories to determine the quality and performance of calcium oxide (CaO) when hydrated.
Constructed from corrosion-resistant stainless steel or anodized aluminum, the vessel features a single or double-walled insulated chamber, ensuring precise temperature measurement without external heat interference. It is engineered in accordance with ASTM C110 – Standard Test Methods for Physical Testing of Quicklime, Hydrated Lime, and Limestone.
Description
Working Principle
Quicklime reactivity reflects how rapidly and intensely calcium oxide reacts with water. A higher temperature rise indicates higher reactivity and better lime quality.
The AZA0810 Slaking Vessel measures this exothermic temperature rise:
-
A fixed mass of quicklime (typically 150 g) is placed into the vessel.
-
A controlled amount of distilled water (approximately 600 mL) at a known starting temperature is added.
-
A precision thermometer or thermocouple is inserted through the central thermometer port.
-
The peak temperature and the time required to reach it are recorded.
This helps identify whether a lime sample exhibits low reactivity (slow slaking) or excessively high reactivity (risk of spattering or violent slaking).
