My kid asked me why concrete is gray and I had no good answer
So my 8 year old was watching me patch the driveway last weekend and just hit me with it. 'Dad, why is concrete always gray?' I froze. I started mumbling about cement and aggregates, but she just looked at me and said, 'But we can make paint any color. Why not concrete?' It hit different coming from a kid, you know? I've been doing this for 12 years and just accepted it as a fact. Now I'm down a rabbit hole looking at colored hardeners and integral pigments. Has anyone here done a legit colored slab for a residential job, like a patio or something? What's the real cost and hassle factor compared to regular gray?
