CONCRETE TESTING
West-Test’s Concrete testing service specialises in tracking the compressive strength of concrete.
The testing is required for any concrete mixture that is to become a supporting structure. For example the foundations of retaining walls, sheds, houses, swimming pools, bridges and buildings.
Concrete Sampling and Compression testing is important to;
- Verify concrete mixture proportions
- Ensure concrete meets the requirements of job specifications
- Allow concrete producers to make informed and responsive decisions on concrete/building projects
- Provide quality control
- Conform to accepted Australian Standard Practice
- Determine the appropriate time when structure is permitted to put into service
- Evaluate the adequacy of concrete
The Process:
West-test provides a field testing service. This involves a trained technician to visit your project site to take fresh concrete samples (3 minimum) directly from the concrete pour. During sampling, the technician will record all potential variables such as temperature, air content and density, and perform a slump consistency test. This slump test will measure the water to concrete ratio of mixture which needs to comply with Australian Standards, as it will affect the strength of the concrete. If test result is negative,Client or concrete producers are informed and can act immediately to rectify proportions. The fresh concrete samples are made and cured into test specimens inside specialised cylinders and left overnight at the site. The next day, the technician will collect test specimens and bring to the laboratory to cure in temperature monitored containers. Then, in specified interval periods (Generally 7 days, 28 days, 28 days), each test specimen is retrieved from curing enviorment and crushed using a calibrated NATA certified, A grade compression machine. After each sample is compressed, a report is sent to the client or concrete producer to check if results meet their job specification and allow them to make informed decisions on the process of the project.
West-Test also can test in and out of metropolitarian areas. Please contact Maurice on admin@west-test.com.au for more details.
