DLC VIBRATING HAMMER FOR CONCRETE MOULDS AZA1169

AZA1105 Chase Air Indicator is a compact, lightweight, and highly practical field instrument designed to measure the air content in freshly mixed concrete. It is widely used in construction sites where rapid quality decisions are required and laboratory testing equipment is not readily available.

This device serves as a reliable field alternative to standard air content methods such as ASTM C231 (Pressure Method) and ASTM C173 (Volumetric Method). While it is not intended to replace laboratory-grade instruments, it provides fast, useful guidance that helps engineers and site supervisors maintain proper concrete mix quality.

Air entrainment plays a critical role in concrete durability, especially in regions exposed to freeze–thaw cycles, and contributes significantly to workability and pumpability of concrete. AZA1105 helps ensure that air content remains within the recommended range (typically 4%–7%), reducing the risk of weak or brittle concrete.

The working principle is based on fluid displacement and vacuum pressure balance. A representative mortar sample is collected and placed inside the testing chamber, where a controlled vacuum is applied. The internal pressure difference is translated directly to a calibrated dial gauge showing the approximate air content percentage.

With no electrical components, moving mechanical assemblies, or complex maintenance requirements, the AZA1105 is extremely reliable and built for tough field conditions. Its rugged body and easy-to-read dial make it suitable for continuous daily use in real-world jobsite environments.

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.

The AZA1126 Plastic Cube Mould is a precision-engineered solution designed for casting 150 mm × 150 mm × 150 mm concrete cubes used in compressive strength testing. Manufactured from high-impact, corrosion-resistant plastic, this mould offers an excellent balance of durability, ease of use, and portability—making it ideal for laboratories, construction sites, and training institutes. Its modular construction, consisting of detachable side walls and a sturdy base, allows for fast assembly and easy demoulding. The smooth internal surface ensures the concrete cube is removed cleanly without surface defects, supporting consistent, repeatable test results. Unlike metal moulds, the AZA1126 is lightweight, rust-free, and requires minimal maintenance, even in humid or coastal environments. The mould complies with IS 10086 and BS 1881-108, ensuring suitability for standardized concrete compressive strength testing procedures.

Early-Setting & Strength Assessment Tool for Concrete and Mortar The AZA1114 Pocket Concrete Penetrometer is a compact, precision-engineered testing instrument designed to measure the initial and final setting times and early strength of fresh concrete and mortar. Built for field engineers, QC inspectors, and laboratory technicians, this spring-type penetrometer provides quick, reliable results aligned with ASTM C403 and IS 8142 standards. Engineered for portability and durability, the AZA1114 delivers consistent penetration resistance readings directly in MPa or psi, making it an essential device for construction sites, precast facilities, mix design studies, and shotcrete applications.
