Hammer Test For Concrete

18 Februari 2021 MINING MINERAL CIVIL LABORATORY SURVEYING BLOG

HT-225D Concrete Test Hammer is an integrated digital concrete test hammer which combines data processor and concrete test hammer into one unit. It is widely used for non destructive testing quality of concrete testing and building materials testing in finished concrete structure or prefabricated blocks.

From its rebound value, the compressive strength of concrete can be calculated out automatically.All testing data can be stored in memory and transferred to PC by USB cable or wireless by Bluetooth.

Key Features

High contrast OLED display
All setup can be made on site
Automatic calculating compressive strength
Automatic correction of impact direction
All data will be stored in memory
All data can be transferred to PC by USB cable or bluetooth (optional)
Dual display for analogue ruler and digital value.

Proceq - Concrete Hammer Test

Non-destructive measurement of the concrete compressive strength and control of the uniform concrete quality (in-situ concrete and prefabricated structures)

• Detecting weak spots

• Data-Transfer to PC/printer

• Data Evaluation with ProVista Software

Concrete Testing with original DIGI-SCHMIDT Hammer, types ND and LD

By entering the depth of carbonation, the conversion of rebound value to the compressive strength is automatically compensated.

The classic ORIGINAL SCHMIDT concrete test hammer is equipped with a sensor which measures the rebound value of a test impact to a high resolution and repeatability. Basic settings and measured values are shown on the display

unit. Operating is menu-guided in different languages.

The DIGI-SCHMIDT is available in two versions:

·Type ND (impact energy 2.207 Nm) - suitable for use on concrete components of 100 mm thickness or more

·Type LD (impact energy 0.735 Nm) - suitable for use on concrete components of thickness less than 100 mm (e.g. precast elements) and on cast stone material

Standards:

ISO DIS 8045, EN 12 504-2, ENV 206, ASTM C 805, ASTM D 5873 (rock) , DIN 1048 Part 2, B-15.225, NF P 18-417,( J6J / T23-2001, JJG 817-1993, both China )
