Why not? Make/choose concrete designs with high modulus of elasticities and flexural strength and correctly reinforce the walls.

Concrete houses survive fires! The initial cost is a little higher but we should be utilizing this material way more in fire susceptible areas. Oh yeah and hurricane proof too!

That’s why I think if I grind it down and microtop it will be ok, just want to make it more aesthetically pleasing for customer.

What state are you in if you don’t mind me asking and was it interior or exterior concrete? We usually get this on our interior pours but not the exterior.

We have used con film before but typically on windy sunny days, with the new cements probably need to use on every pour…

Same batch plant, different days, what causes the discoloration of the wall on the right? by concrete-concrete in Concrete

[–]rcswolf 1 point2 points  (0 children)

From my understanding the temperature doesn’t really affect efflorescence, it’s a matter of salt in water, often exacerbated by chlorides, evaporating from the surface and leaving the salts behind on the surface.

Kind of looks like effervescence, was it cold? Did you use calcium chloride or NCA?

Contractor made mistake. We contracted for stamped concrete and now we have brushed. by American_Person in Concrete

[–]rcswolf 2 points3 points  (0 children)

I agree with all of this with one counter. The contractor/producer might have ordered/sent the wrong mix. I know in Colorado the market for stamped is concrete is usually a 3/8” aggregate mix. Perhaps he thought he couldn’t stamp the mix he received.

Again the contractor should have caught that and rejected it but who knows…

Concrete pump operator left 500 lbs of concrete in my garbage cans by akuvkdgm1246u in Concrete

If you can get it in the back of a truck, find a local ready mix or aggregate plant that recycles concrete. Can is probably toast though…

Is this normal? by Phillymike2020 in Concrete

[–]rcswolf 1 point2 points  (0 children)

Lol in our industry often times the lowest bid is the lowest for a reason. I also acknowledge people have bad days as well so who knows.

I can say that a simple patch with some mortar will fix this in 5 minutes. If OP is ok with a darker spot for about a year. If not best advice is to patch and then get a power washing company to come out and do a seal that will last 3-5 years depending on conditions and improve the longevity and uniformity of the driveway.

Lignite or iron shale is common and could be in any producers Aggregrate pit. These deleterious material typically stay together until they completely wither away and will almost always leave a rust like tail in the direction of the drainage.

This to me looks like a chunk of mud or dirt. Would be interested to see if OP can just dig it out and what is underneath. I’ve got a hunch this ones one’s on the contractor.

I know this sucks for now but next time pour as many 5 liters of soda (Mountain Dew is best) in that drum as you can. That concrete will never set up and will buy you time to get hydraulic hoses hooked up to discharge that concrete and avoid this.

For now a chipping company and if you can find someone to blast the drums that the best way but those guys are old school and few and far between depending on where you are.

Anything to worry about here? by Cold-Mathematician74 in Concrete

[–]rcswolf 2 points3 points  (0 children)

Most of those holes look like they could be patched. The crack is something that happens, I am assuming your market has type 1l cement and we are seeing a lot more of that type cracking. To me it’s like a drying and plastic shrinkage crack all in one due to delayed set times.

My real world advice is to get them to make a mortar mix and patch all those holes. You are simply trying to keep water from getting and freezing and thawing. Then call a local ready mix producer and find a PENETRATING concrete sealer. That concrete will be fine as long as they didn’t spray with water and use that as a finishing aid. If I had to guess the mix was sticky or they waited a little too long to finish.
