Good concrete –bad concrete: Code vs. Reality


If you are a contractor, testing agency or a supplier, you are all too familiar with ‘concrete didn’t show up on time’ problem. To give each party a say, we have put together a group of experts to discuss several ‘crossing-the-fine-line’ situations with concrete deliveries. They will discuss basic questions which fall in the grey area between code vs. practicality; questions most inspector/testing agencies would rather respond to with a ‘Well…depends’. To use that truck or send it back? How many minutes do I really have from batch time, its definitely not exactly 90min? What is the tolerance on slump? How do concrete suppliers plan trucking based on day of the week and time of day. Low breaks: who’s fault is it anyways and what are my tolerances? And many more. Bring your burning questions along we will have answers from all sides…
