How to choose a concrete compression machine?


    A concrete compression machine uses compressive pressure to load various concrete specimens to ensure that the material meets structural integrity and design requirements. These multifaceted machines are the core of any cement testing lab. Several compression machines allow modifications that help them adapt to a variety of specimens, and the appropriate one can shape the effectiveness of your testing program.


    Perks offered by a compression machine

    Technical advancements have led to enhanced efficiency, repeatability, performance, and accuracy for testing mortar, grout, and concrete strengths in a wide range of sample types. The cement testing lab equipment manufacturers in China equip these machines for a single specimen type. But these manufacturers can furnish them with adaptive amenities for testing multiple specimen varieties and sizes.


    Selecting a concrete compression machine

    Here you have a purchasing guide to help you choose the most suitable adaptive accessories and concrete compression machine for your cement testing needs.

    • Frame Stiffness andCapacity-The National Ready Made Concrete Association says that the integral strength of concrete is the key parameter checked by the engineer when designing buildings and other structures. Secondly, only those cement testing lab equipment suppliers in China can meet your requirements whose concrete compression machine complies with ATSM, AASHTO, and ASTM C39 standards.


    • Sample Strength and Types - The size of samples influences the maximum testing capability of the machine. A compression machine with a capacity of 260,000-pound-force can test 6x12in cylinders with estimated toughness up to about 7,000 pound-force per square inch.


    A few other variables to be kept in mind while purchasing from cement testing lab equipment suppliers in China are as follows:

    • Compatibility:  As stated earlier, there are multifaceted accessories to modify your compression machine for more than one type of testing. Testing concrete samples means ensuring that the machine has consistent accuracy with lower loads.

    • Strength:  Explosive failures can be perilous due to flying fragments and may shock the hydraulics and electronic systems of the machines. You must ensure that the compression machine is furnished with fragment guard doors and other safety equipment.

    • Type of Test:  In addition to ASTM and AASHTO, a few other industry standards followed by cement testing lab equipment manufacturers in China include BS 1881, BS 1610, AASHTO T 22, ASTM E4, ASTM C78, and ASTM CLO09.

    • Features:  Look for reliable hydraulic valve controls and two-stage hydraulic systems. A costly operational error is allowing the hydraulic ram to exceed its capacity. So you must select a design with a bleed hole to balance pressure – and ensure precise surveillance on the maximum extension. 

    • Multifaceted adaptive equipment

    Once you have assessed capabilities, capacities, and other features, choose accessories that allow modification according to your applications. Several accessories are multifaceted that facilitate the effectiveness of each compression testing machine by furnishing it with devices that raise the testing capability.



    We are sure that the information within this blog will help you choose a suitable compression testing machine that maintains quality assurance protocols and quality control, adheres to industry recommendations and standards, and gets the job done the first time.
