Hello, could anybody tell me how we can state the number of SRI tests on a project? We intend to place gravel on the roof and provide a concrete parking log.
Is one test for the whole concrete or gravel delivery from the same supplier for one roof or parking lot suffiecient or must each delivery be tested?
A quarry has various colors of stones and gravel - how can we decide how many tests of SRI we have to provide for gravel which we intend to place on the roof?
Supposed it should be documented for each batch of gravel - how is a batch determined?
Thanks
