In deciding on a method for monitoring and measuring the strength of concrete It is important that project managers consider the impact that each technique will have on their timetable. While certain tests can be carried out on site while others call for additional duration for Third-Party facilities in order to provide the strength information. It is not the only factor contributing to decision-making by project managers. The precision that the test process has is as important because directly affecting how well the structure is constructed.
The most popular method for testing the strength of in situ concrete is to use field-cured cylinders. This method has remained largely unchanged from the beginning of the 19 century. century. The slabs are casted and then cured in accordance with ASTM C31 and tested for compressive strength by a third party lab at various times. Typically, when the slab is at 70% of intended strength, engineers approve their team to proceed to the next step in the process of construction.
There have been numerous improvements to speed up curing since the method of testing was first made available. It includes heating blankets, add-ons and vapor retarders, for instance. However, contractors are still waiting three days following the pour before testing the strength of their product, even though their goals are usually attained sooner than that..
Even though they know this most project managers would choose to stick with this method of testing as this is “the way its always been done.” But it doesn’t mean that it’s the fastest and most precise method for test the durability of their pours. There are a variety of methods apart from the cylinder break test and cylinder break tests, that are able to be used. Here are seven methods to think about when selecting the method for strength testing:
