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.
