Standard: EN 196-1, ASTM C 305, AASHTO T 162, ISO 679

Product Description

Automatic mortar mixers are machines designed specifically to streamline the mixing process. In construction, mortar is a vital material used for binding bricks, stones, or other building units together. It's essentially a mixture of cement, sand, and water. Mixing mortar manually can be time-consuming and physically demanding, especially for larger construction projects. That's where automatic mortar mixers come in. They typically consist of a rotating drum or paddles where the ingredients are loaded. Once the ingredients are added, the mixer automatically rotates or agitates them to ensure thorough blending. This automation saves significant time and effort compared to mixing by hand. This apparatus has specially been designed to prepare cement mortar for strength determination as specified in standard. It can also be used in mixing lime with pozzolanic materials for determination of lime reactivity (as per IS 1727) & for uniform mixing of soils with additives such as lime, cement, etc. New Mortar Mixer comes with built in door for better safety.

Features of Mortar Mixer 

  • Automatically mix mortar ingredients, such as cement, sand, and water, without requiring manual intervention.
  • Efficient loading and unloading mechanisms, such as tilting drums or removable mixing paddles, make it easier for operators to add ingredients and extract mixed mortar.
  • Automatic mortar mixers can be powered by electricity, gasoline, or diesel, providing flexibility for use in various environments and situations.
  • Offer variable speed settings, allowing users to adjust the mixing speed based on the type of mortar being prepared and the desired consistency.

Standard: EN 196-1, ASTM C 305, AASHTO T 162, ISO 679

  • EN 196-1

This standard is indeed crucial for assessing the strength and quality of cement, which is vital for ensuring the safety and durability of construction projects. By covering procedures for various strength tests and properties assessment, EN 196-1 provides a comprehensive framework for quality control in cement production and construction. The widespread adoption of EN 196-1 in Europe and other regions that adhere to European standards highlights its significance in upholding uniform quality and reliability standards within the cement industry.

  • ASTM C 305

This standard establishes mechanically mixing hydraulic cement pastes and mortar with a plastic consistency. Guidelines are provied for the mechanical mixing of cement pastes and mortars to make sure the consistency and accuracy in laboratory testing. Unites States and other region where ASTM are recognised uses this standard. This is to ensure the consistency in how cement-based materials are being used for testing and research objectives.

  • AASHTO T 162

This standard specifies in the particle-sized analysis of soils. It outlines the steps of perfroming particle-size distribution analysis on soil samples through mechanical sieving techniques. This standard holds particular significance in soil examination within transportation infrastructure challenges, aiding engineers and geotechnical experts in comprehending soil characteristic essesntial for designing.

  • ISO 679 

This standard, ISO 679 outlines a procedure for assessing the water requirement, setting time, and soundness of hydraulic cement. It provides guidance for conducting tests to measure these properties, ensuring consistency and reliability in construction materials. Its utilised worldwide, ISO 679 serves as a standard method for evaluating the performance and quality of hydraulic cement. 

Test Procedure

  1. Preparation: Make sure the Mortar Mixer is placed on a flat surface. Check the power source and ensure its connected and functional. Inspect the Mortar Mixer for any defects before use. 

  2. Ingredient Management: Measure the appropriate amount of dry mortar mix and water as per the manufacturer's instructions before loading the dry mix and water into the mixing drum of the mortar mixer.

  3. Loading: Open the mixer's access point, whether it's a hinged lid or a tilting drum, and carefully pour in the measured ingredients in the recommended sequence, typically starting with sand, followed by cement, and then water. Once all the ingredients are added, ensure the access point is securely closed to avoid any spillage while the mixing process is underway.

  4. Setting Parameters: Set the desired mixing parameters on the mixer's control, such as mixing speed, duration and other relevant setting.

  5. Mixing: Commence mixing following the guidelines provided by the manufacturer. Keep a close eye on the blending process to confirm that all ingredients are thoroughly incorporated and that the mixer functions without issues. If needed, modify the mixing settings to attain the desired texture and uniformity in the mortar mixture.

  6. Sampling: Throughout the mixing process, intermittently collect mortar samples to evaluate its consistency, workability, and other characteristics. Conduct necessary assessments on these samples, including slump tests or compressive strength tests, to gauge the mortar's quality and suitability for the intended application.

  7. Completion: After finishing the mixing, halt the mixer when the mortar achieves the desired texture. Unfasten the loading mechanism and extract the blended mortar from the mixer. Thoroughly cleanse the mixer to prevent any contamination and ensure its optimal performance for subsequent use.

  8. Documnetation: Document all aspects of the mixing procedure, such as the ingredients employed, mixing settings applied, test outcomes, and any observations or modifications enacted during the process. Maintain comprehensive records to facilitate quality assurance, project documentation, and reference purposes in the future.

  9. Safety Precautions: Follow all safety protocols and guidelines outlined by the manufacturer and applicable regulations consistently throughout the testing process. Verify that all individuals participating in the testing are adequately trained in the safe utilization of the mortar mixer and associated machinery.
