Air Entrainment Meter for Mortar (1 Litre Capacity)
NL 3036 X /

Standard: EN 413/2 – DIN 1164

Product Description

The Air Entrainment Meter for Mortar is an equipment used in construction and civil engineering to measure the air content in fresh mortar samples. The 1-litre capacity refers to the volume of the container used to hold the mortar sample during testing. The evaluation of air content in mortar is an important parameter to assess because it affects the durability, workability, and strength of mortar. The presence of air voids in mortar can have significant effects on how well it performs in construction projects, particularly in applications like masonry construction. These voids can weaken the structure and reduce its durability. Connected to a dial gauge directly the air entrainment in range of 0 – 50%. It is cast aluminium built, the test pot and the upper part are air-tight sealed. The product is identical to model NL 3034 X / 001 but the process using an electric mini-compressor that give air pressure and keeping it constant during a test.

Features of Air Entrainment Meter for Mortar

• Pressure Control System to ensure the pressure applied to the mortar testing is being controlled. Provides accurate measurements of air content.
• Pressure Gauge helps in ensuring the consistency and accuracy of mortar testing process.
• 1-Litre capacity to hold mortar sample during the testing prcoess.
• Pressure Gauge & Release Valve to ensure accurate testing and accurate measurement of air content. 

Standard: EN 413/2 – DIN 1164

• EN 412/2 

This European standard specifies in the steps for evaluating the mortar quality, especially by measure the amount of air content in freshly mix batches. It covers from the tools needed, collection of samples, conduct tests, and record findings. Following these guidelines when testing air entrainment helps guarantee the quality of mortar standards is up to par. By complying with this standard, builder can trust that their mortar will be consistent and reliable, which is crucial for making strong and durable structures. 

•  DIN 1164

This German standard focuses on mortar testing methods. It addreseses multiple aspects of testing, including evaluating properties like consistency, density, and air content. The purpose of DIN 1164 guidelines is to aid in the testing of mortar samples to ascertain their suitability for various construction projects. Adherence to DIN 1164 ensures that mortar meets the necessary quality and performance criteria for specific tasks within construction. By following these guidelines, builders can verify that the mortar they use possesses the required properties and characteristics, thereby enhancing the overall quality and reliability of construction projects.

Test Procedure

1. Mortar Sample Preparation: Prepare fresh mortar sampling according to the desired mix design and specifications.
2. Equipment Setup: Make sure to set up the Air Entrainment Meter according to the manufacter instructions.
3. Fill & Seal Container: Place the 1-liter capacity container of the Air Entrainment Meter on a stable surface. Carefully fill the container with the prepared mortar sample, ensuring it is level and free of air pockets. Securely seal it to prevent any air from escaping during testing. This may involve placing a lid or cover over the container and ensuring it is tightly secured in place.
4. Apply Pressure Changes: Use the Air Entrainment Meter to subject the mortar sample to a series of pressure changes. This typically involves applying a vacuum to the sample and then releasing the vacuum in a controlled manner. The pressure changes help to release any entrapped air bubbles from the mortar. 
5. Measure Air Content: The air released from the mortar sample will, it rises to the top of the container. Utilise the equipment's measuring gauge or scale to quantify the volume of air released. This measurement is typically expressed as a percentage of the total volume of the mortar sample.
6. Record Results: Make sure to document the measured air content, noting the date and time of testing, details about the mortar mix used, and any specific conditions during testing. This record helps maintain a thorough history of the test and provides valuable information for analysis and comparison
7. Repeat if Necessary: Repeat the procedure with additional mortar samples to ensure consistency and accurate findings. Only repeat if required by specific testing standards. 
8. Interpret Results: Measured air content should be analyse in order to verify whether its in acceptable range for specific projects or specifications. Adjustment is necessary if measured air content doesn't align with desired target. 
9. Report Findings: A report summarising the test procedure, results and any relevant observations. This report may be used for making sure everything meets quality standards.
