Since 2001, Zumtest has been manufacturing concrete cube and cylinder specimen molds. What began as a mission to meet our own laboratory needs quickly evolved into a growing production capacity and expanding product range—making Zumtest a trusted choice for private and public laboratories both in TÜRKİYE and internationally.
Zumtest concrete specimen molds are successfully used in the laboratories of many leading institutions, including the Ministry of Environment and Urbanization, the General Directorate of Highways, DSİ, universities, and ready-mixed concrete companies. Beyond TÜRKİYE, they are also an integral part of concrete testing processes in countries such as Australia, South Africa, Hungary, Poland, Russia, Bulgaria, Romania, Serbia, North Macedonia, Iraq, Iran, and Azerbaijan.
Our molds are manufactured using two different materials—BMC (composite) and polyurethane—fully compliant with TS EN 12390-1 standards and supplied with calibration assurance.
Our composite products are locally manufactured, offering greater durability than plastic molds while being lighter and more cost-effective than steel molds.
Quality Processes
R&D Studies and Tests conducted to produce the best concrete molds in Türkiye
Non-Destructive Compressive Strength Test
This is one of the most commonly used tests to determine the strength of concrete. In this test, cylindrical concrete specimens of standard dimensions are formed in a laboratory environment, and pressure is applied to these specimens after a certain period of time. The strength of the concrete is determined by measuring how much pressure the specimen withstands until its fracture point.
Hardness Test
The surface hardness of concrete is an important factor affecting the durability of the structure. A hardness test is performed by applying a specific load to the concrete surface and scratching or crushing the surface. This test is used to check whether the concrete mix has been prepared correctly to provide the appropriate hardness for the structure.
Water Permeability Test
The water permeability of concrete indicates its ability to protect the structure from moisture and water damage. In this test, water permeability is measured by applying a certain water pressure to the concrete sample. Lower water permeability means more durable concrete.
