DENSITY OF FRESH AND HARDENED CONCRETE AZA1132
The Azalab Density Apparatus AZA1132 is a precision-engineered system designed to measure the density of both fresh (plastic) and hardened (cured) concrete. Conforming to IS 1199 and ASTM C642, it is essential for material testing laboratories, construction quality assurance teams, and field technicians who require accurate and consistent density evaluations.
Density is a key parameter that influences concrete strength, durability, compaction quality, and structural performance. The AZA1132 enables reliable assessment at every stage of the concrete lifecycle—ensuring mix design accuracy, detecting voids, and verifying on-site production consistency.

Description
Technical Overview
Fresh Concrete Density
Using a calibrated density container:
-
Fill, rod, or vibrate the container to eliminate air voids
-
Record weight
-
Compute density using weight ÷ volume
This process verifies mix uniformity, yield, and air content control.
Hardened Concrete Density
Using water displacement (Archimedes’ method):
-
Weigh specimen in air
-
Weigh specimen in water using suspension frame
-
Volume and density are computed from the difference
This identifies internal deficiencies such as voids, honeycombing, or poor compaction.

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.
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
