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.

The AZA0802 Jolting Apparatus is a precision-engineered laboratory instrument designed for uniform compaction of cement mortar specimens, ensuring reproducibility and accuracy in strength testing. It plays a vital role in preparing mortar prisms for compressive and flexural strength tests, eliminating air voids and ensuring homogeneous density throughout each specimen.

Manufactured in accordance with IS 10080:1982, and suitable for use under EN 196-1 and ASTM C348 testing standards, the AZA0802 is essential for any laboratory involved in cement quality evaluation, research, or certification.

Whether used in construction QC labs, cement manufacturing units, academic institutions, or R&D centers, the AZA0802 offers dependable, consistent, and safe compaction performance for standardized mortar testing.

Why Compaction Matters in Mortar Testing

The quality and reliability of mortar strength tests depend heavily on the degree of compaction during specimen preparation. Air voids, improper leveling, or inconsistent compaction can lead to inaccurate test values and unreliable performance assessments.

The AZA0802 utilizes a mechanical cam-driven system delivering 60 precise jolts per minute, effectively removing entrapped air from the mortar mix. An inbuilt 60-second automatic timer ensures standard-compliant compaction by stopping the machine after the required number of jolts.

This ensures:

• Highly consistent mortar density

• Repeatable strength results

• Compliance with national and international testing standards
