INITIAL SURFACE ABSORPTION TEST (ISAT) APPARATUS AZA1108
AZA1108 ISAT Apparatus is a precision-engineered testing instrument designed to measure the Initial Surface Absorption of hardened concrete. This test is essential for evaluating the durability of concrete by determining how quickly water penetrates the surface under controlled conditions. The apparatus is widely used in civil engineering laboratories and quality control departments to assess permeability and long-term performance of concrete structures exposed to moisture.
Built with a high-accuracy capillary tube system, the AZA1108 maintains a constant water head over a defined test area and records the volume of water absorbed over specific time intervals — typically at 10, 30, and 60 minutes. The readings obtained help engineers understand the surface porosity of concrete, which is a critical indicator of resistance against weathering, chloride ingress, corrosion of reinforcement, and environmental deterioration.
Designed in compliance with BS 1881-208, this apparatus ensures reliable, repeatable, and standard-compliant results. Its sturdy, rust-proof construction and easy-to-use configuration make it ideal for both routine testing and advanced durability studies in construction material laboratories.
J-RING, NARROW GAP AZA1109
AZA1109 J-Ring – Narrow Gap is a precision testing apparatus designed to evaluate the passing ability of Self-Compacting Concrete (SCC) under highly restrictive conditions. This device simulates densely congested reinforcement zones by creating artificial obstructions that the fresh SCC must flow through without blocking or segregating. It is an essential tool for determining whether SCC mixes are suitable for heavily reinforced structural elements such as beams, columns, and shear walls.
The narrow gap design offers a more stringent test compared to standard J-Rings, allowing engineers and quality control professionals to accurately observe flow diameter, T50 flow time, and blocking behavior. When used in combination with a standard slump flow cone, AZA1109 provides reliable, repeatable results that help optimize mix designs and ensure consistent on-site performance.
Manufactured from durable, corrosion-resistant steel, the AZA1109 is built for repeated use in laboratory and field testing environments. The apparatus is fully compliant with ASTM C1621 and EFNARC guidelines, ensuring internationally accepted testing procedures.
K-SLUMP TESTER AZA1104
AZA1104 K-Slump Tester is a fast, reliable, and non-destructive testing device designed to measure the workability and consistency of fresh concrete directly at construction sites or in laboratory environments. It provides instant slump approximation without the need for traditional slump cones, base plates, or tamping rods, making it an essential tool for modern concrete quality control.
This handheld instrument is widely used by civil engineers, site technicians, and quality inspectors who require quick, repeatable, and real-time results during concrete batching, transportation, and placement. Its simple design eliminates complicated setup, reducing testing time and operator fatigue.
Manufactured from high-grade stainless steel, the probe is corrosion-resistant and suitable for harsh site conditions. The etched scale markings provide direct readings in millimeters or inches, allowing accurate penetration depth measurement without additional instruments.
Unlike traditional slump testing methods, the AZA1104 enables non-destructive testing, meaning the concrete surface remains intact and usable after testing. This feature is especially useful when multiple checks are needed during large pours or continuous batching operation
