Re: Best method of curing an exposed aggregate driveway? 10Mar 17, 2011 8:19 am OK, I'm reading this thread back to front (almost) ... jsut noticed that he wants to dowel your dwy into the garage slab??? Is it really warranted?? I would definitely just ask him for the expansion "sponge" to be placed against the old concrete (ie. your house slab) and not let him touch the slab. BTW, from all that you've mentioned, I would also not give him the job. My signature is distracting people from my wise posts ...

Re: Best method of curing an exposed aggregate driveway? 12Mar 17, 2011 11:31 am I need to ask a silly concreting question and don't want to start a new thread just for that, so I will hijack this a little. OK, here it goes: How can we know if the truck driver is adding water to the mix? I mean, is that really easily visible from the outside, or does he have a 'secret' pipe passageway hidden or more protected from external view, where the water pipe plugs directly into the mix 'drum'? I found this doco http://www.concrete.net.au/concrete_structures/residential_documents.php?id=176&page=1 where it says: "3. If additional water is requested, the driver has been instructed [by who?? the concretor??] to obtain a legible name and signature from an authorised person on the delivery docket before adding any water." Onc, so dowelling is OK? What is 'sandjacking' - escape of sand in between the heavy concrete and the sponge? Or not ... My signature is distracting people from my wise posts ... Re: Best method of curing an exposed aggregate driveway? 13Mar 17, 2011 12:50 pm Sand jacking is where water enters the 'joint' and either washes away(compacts) sand from under the concrete 'without' a footing. Water added is upto the grano... ... if the grano is any good they will know exactly how much water to add to bring the mix upto 80 slump or more if needed(& within spec). Some will add more, some will struggle with less and the concrete will suffer as the surface could be difficult to 'close' & and compaction might be under done. The water adding pump and hose is at the back of the truck and the water goes through a meter, so that and exact idea of added water is known. The whole thing is too complex to discuss here.. but I have NEVER been asked to sign for adding water.. in 25+ years and we go to very highly specified jobs. Added water is not the responsibility of the driver, they are drivers NOT concretors(Granos) Where you are coming from is where you are going to... Re: Best method of curing an exposed aggregate driveway? 14Mar 17, 2011 12:58 pm Thanks, onc ... So, I can easily see if some water-adding action is happening?? Also, would you agree that it is easier for the grano to work with a higher strength concrete, 32 and above? My signature is distracting people from my wise posts ... Re: Best method of curing an exposed aggregate driveway? 15Mar 17, 2011 1:31 pm Some will complain, some will be happy. For me it is about the needs(engineering of the job) neither are easy, The grey lady is a strange beast, treat her well and you are in front, poorly treated the she will control you and that is where the problem arises. The more cement the faster hydration occurs and becomes 'plastic... bleed water then cure' in a hurry. Closing the surface becomes problematic and why chips, blowout, crazing and cracks happen.

Re: Best method of curing an exposed aggregate driveway? 18Mar 18, 2011 7:44 am Aiah So much fear and distrust associated with the placement of concrete, We need a thread with positive concrete stories complete with pics of the awesome and unusual applications it can be used for. ... I always wonder how come most of the threads I read go like "Our installer / concretor / trader took care of everything ... he took care that xxxxxx, so the finished job was beautiful ..." and so on. We had no such experiences (yet). Therefore all the fear and anxiousness. Another really bad thing for the owner - the more you know about the steps or materials, etc., it simply doesn't help in the end. Just gets you more frustrated when you see how and what they do. We're talking about things that are so simple and common sense, not worth discussing, as they are a given in specific trades. Still, opposite happens.
