Everyone in the construction industry is aware of the importance of concrete strength. It is basically the performance measure used by engineers while designing buildings and other concrete structures. The test helps to ensure that the concrete mixture delivered by your concrete suppliers meets the requirements of the specific strength.
Since concrete strength is so important, it is always advisable to evaluate the strength of the concrete you are using on-site before starting with your construction project. The first thing you need to do is to get in touch with renowned concrete suppliers and they will share with you a few easy tips.
4 Tips By Concrete Suppliers In Croydon To Evaluate The Strength Of Concrete On-Site
- Compression Test For The Cores
Compression test on concrete cores is regarded to be the most reliable solution if you want to test the structure for strength. First, cut the core and prepare the surface. One of the primary benefits of using this method to evaluate the compressive strength of concrete is that it is relatively fast. Just don’t forget or neglect to repair the core after the test has been conducted.
- Pull-Out Test
Early diagnosis of concrete strength problems becomes easier with the pull-out test. Get in touch with experienced professionals as they know how to evaluate concrete strength in existing structures. Small equipment will be attached with the exterior nut, bolt, fixing or screw before pulling it to the designated stress load level. This helps in determining the strength of the fixing. Concrete suppliers opt for this pull-out test as it is relatively easy to use and helps in delivering robust results.
- Rebound Hammer
A spring driven hammer is used to hit the concrete before measuring its rebound. This test is based on the rebound principle. Its primary objective is to evaluate the hardness of the surface. It was introduced in the year 1948 and has since then been widely used. The convenience and simplicity of the method have enhanced its popularity. Some empirical correlations were later established between the rebound number and the strength properties of the structure. The test helps concrete suppliers in Croydon to evaluate the uniformity of concrete.
- Combined Methods
Various NDT methods are combined to evaluate concrete strength online. Several researchers have highly suggested including the rebound hammer method and the UPV method. When various methods are combined, the results delivered are more comprehensive. The accuracy of the prediction can also be improved by using various correction factors like the influence of the cement content, fine aggregate fraction, cement type, aggregate maximum size and petrologic aggregate type. These being said, it’s time to follow the tips stated above and get in touch with renowned concrete suppliers if you want to evaluate the strength of concrete on-site.
