Concrete Strength Testing and Laboratory Analysis
Comprehensive laboratory tests are performed to evaluate the quality of concrete elements and pipes. Mechanical performance is analyzed through compressive strength, air content, elasticity modulus, and composite reinforcement tests. Advanced testing machines and precise sensors verify standard compliance, load-bearing capacities, and structural durability.
Axial Extensometer (Compressometer)
Axial extensometer is designed for the determination of the modulus of elasticity in compression of mortar, cement, concrete, rock and other materials.
Test Samples
Test specimens after testing still equipped with the extensometric cage. Laboratory tests are performed to evaluate the durability and performance of epoxy resins; often used to re-evaluate all or part of the epoxy resins after testing
Air Meter
Checking the air content of concrete elements with an air meter is a vital test used to ensure durability against freeze-thaw cycles and proper structural integrity in construction projects.
Compressive Strength Test
The concrete cube compressive strength test is a mechanical method that measures the maximum load that a cube or cylindrical specimen can withstand before cracking inside a testing machine.
Concrete pipe machine testing
Concrete pipe testing machines feature a hydraulic power pack, a two-column frame, and an upper beam actuator equipped with an anti-rotation system.
Strength of concrete
The strength of concrete is the most important indicator that determines the properties and performance qualities of concrete and reinforced concrete structures.
Installation of test piece and cage on the machine.
Once the test is completed, the spacers are put back in place and the specimen and cage assembly removed from. Specimens after testing still equipped with the extensometric cage
Reinforcement with Composite Material
Reinforcement of concrete with composite materials. Composite materials are used to strengthen concrete for both shear and flexure. This method is aimed at improving the mechanical behavior of concrete elements.

Concrete Compression Testing
A lightweight and low-strength concrete cylinder is being subjected to a load of approximately 25,000 lbs by a testing machine while attached devices measure its length reduction. The rust-colored material is a sulfur cap used to ensure flat ends.
Specimens during the compression test
Concrete pipe test values verify minimum pressure limits. In the negative air pressure test, both ends of the pipe are sealed and the internal pressure is reduced to -3.5 psig.
Chemical additive for concrete,
thanks to superplasticizers, you can use up to 30% less water and up to 10-15% less cement without changing the grade strength of concrete.
Mechanical Strength Specifications by Concrete Class
This table details the mechanical strength specifications by concrete class, covering BS 14 through BS 50. It outlines characteristic compressive and tensile strengths, design values, and cube strength equivalents essential for structural calculations, verifying load-bearing capacity and ensuring full compliance with engineering standards.
