About Concrete Test Hammer (Schmidt Hammer) N Type

Specification:

The quality of concrete is mainly judged by its compressive strength directly affecting the loadbearing capacity and durability of concrete structures. ZI 2068 concrete test hammer (Schmidt Hammer N type) is used to measure the compressive strength characteristics of hardened concrete non-destructively, control uniform concrete quality and detect weak spots in the concrete. The test object should have a minimum thickness of 100 mm.

A concrete test hammer (Schmidt hammer) "N type" specification refers to a device with an impact energy of 2.207 Nm (1.63 ft-lbf), designed to estimate the compressive strength of concrete with strengths from approximately 1,450 psi to 10,152 psi (10-70 MPa). Key features include its standardized impact energy, an analog rebound scale, and its suitability for concrete thicknesses of 4 inches (100 mm) or more and a maximum aggregate size of 1.25 inches. It complies with international standards such as ASTM C805 and EN 12504-2.

Key Specifications for Type N:

Impact Energy: 2.207 Nm (1.63 ft-lbf)
Concrete Compressive Strength Range: 1,450 psi to 10,152 psi (10 to 70 MPa)
Minimum Concrete Thickness: 4 inches (100 mm) or more
Maximum Aggregate Size: 1.25 inches
Standards: Conforms to international standards like ASTM C805, EN 12504-2, JGJ/T 23, and JIS A 1155.
Function: Measures the surface hardness (rebound value) of hardened concrete, which is then correlated to its compressive strength.

Reliable Strength Assessment for Concrete

The Schmidt Hammer (N Type) offers a dependable method for evaluating the compressive strength of concrete, ranging from 10 to 70 MPa. Its direct rebound value reading allows engineers and quality inspectors to quickly determine the structural integrity on-site or in the lab. With its robust aluminum casing and mechanical operation, this device ensures consistent, repeatable results every time.

Designed for Field and Laboratory Use

Engineered with portability in mind, the Concrete Test Hammer comes in a durable carry case with a grinding stone, user manual, and calibration certificate. Its compact design (280 mm length, 54 mm diameter, 1.0 kg weight) allows for single-handed operation. No external power supply is required, making it perfect for remote or challenging site conditions.

Easy Calibration and International Standards Compliance

Each unit is supplied with a calibration anvil, ensuring accurate and reliable measurements. The device fully complies with relevant international standards (IS: 516 Part 5, ASTM C805, EN 12504-2), making it suitable for diverse testing requirements and quality protocols in India and worldwide.

FAQ's of Concrete Test Hammer (Schmidt Hammer) N Type:

Q: How does the Concrete Test Hammer (Schmidt N Type) measure compressive strength?

A: The Schmidt Hammer measures compressive strength by impacting the concrete surface with a defined energy (2.207 Joules) and registering the rebound value on its mechanical analog scale. This rebound correlates directly with the material's compressive strength, providing instant measurements between 10 and 70 MPa.

Q: What surfaces can be tested using this hammer and how should they be prepared?

A: Surfaces tested must be smooth, clean, and dry. Use the included grinding stone to prepare rough or uneven areas. Clean any dust, oil, or debris to ensure accurate readings and consistent contact with the plunger during testing.

Q: When should the calibration of the hammer be performed?

A: Calibration should be verified before first use, after extensive testing, and periodically as recommended in the user manual. The provided calibration anvil allows users to quickly check and adjust the device to maintain measurement accuracy.

Q: Where can this test hammer be used?

A: The Concrete Test Hammer is suitable for both field and laboratory testing. Its portability, manual operation, and durable construction make it ideal for use on construction sites, bridges, buildings, and precast concrete elements throughout varied environments in India.

Q: What is the testing process for concrete strength using this equipment?

A: First, prepare the test surface, then firmly press the hammer's plunger against the concrete until it releases the impact. Instantly read the rebound value (RV) from the analog scale. Repeat the process at several spots to ensure representative results. It's suitable for single specimens of at least 100 mm thickness.

Q: What are the benefits of using the Schmidt N Type Hammer?

A: Key benefits include rapid, non-destructive testing; instant, direct mechanical readings; high portability; compliance with global standards; and suitability for both laboratory and field evaluations without the need for a power supply.
