CAPPING SET (VERTICAL) AZA1164
The AZA-LAB Vertical Capping Set is a precision tool designed to prepare 150 mm concrete cube specimens with smooth, level, and parallel end surfaces prior to compressive strength testing. By holding the specimen upright and ensuring perfect alignment, this apparatus enables consistent and accurate results in accordance with ASTM C617 and IS 516.
Purpose & Function
During compressive strength testing, concrete cubes must have properly prepared surfaces to guarantee uniform load transfer between the testing platens. Any irregularity can cause stress concentrations or premature failure. The Vertical Capping Set provides a stable, guided fixture that maintains the cube in a perfect vertical orientation while capping compound is applied to each end.
Once sulfur or gypsum-based capping material is poured and allowed to harden, the ends become flat, parallel, and ready for precise compression testing in a Universal Testing Machine (UTM).
Description
Robust Construction & Accurate Positioning
Built using heavy-duty, powder-coated steel, the vertical capping set offers excellent resistance to wear, corrosion, and heavy laboratory usage. The precision-machined cube slot ensures that the specimen remains centered and upright with zero lateral shift. Its vertical design saves bench space and supports a more efficient workflow, especially in high-volume laboratories.
The setup features:
• A rigid, open-frame structure for easy cleaning
• Non-slip rubber-coated base for stability during operation
• Guided alignment system for accurate cube positioning
This design minimizes handling errors, improves operator safety, and enables fast, repeatable capping.
Applications
• Construction and QA/QC laboratories
• Independent testing labs
• Ready-mix and precast concrete plants
• Engineering colleges and research institutions
• Infrastructure testing centers

L SHAPE BOX APPARATUS AZA1112
AZA1112 L Shape Box Apparatus is a precision testing device designed to evaluate the passing ability and flow performance of Self-Compacting Concrete (SCC) in congested reinforcement conditions. This apparatus simulates real-world scenarios such as densely reinforced beams, columns, tunnels, and bridge segments, where concrete must flow freely without segregation or blockage.
The distinctive L-shaped design creates a controlled flow path where freshly mixed SCC moves from a vertical chamber into a horizontal channel containing reinforcement bars. By measuring the concrete heights at both ends (H1 and H2), the H2/H1 ratio is calculated, providing a direct, quantitative assessment of the concrete’s ability to pass through obstructions.
Manufactured from durable, corrosion-resistant steel, AZA1112 is built for long-term laboratory and site use. It conforms to EN 12350-10 and EFNARC guidelines, ensuring global acceptance of test results.
