The whole process of concrete hardening after it's been positioned known as curing, and is particularly a slow procedure. It usually can take concrete around 4 months to achieve about ninety% of its remaining toughness, and also the strengthening can carry on for up to three เสาไฟฟ้าคอนกรีตอัดแรง decades.
Concrete is characterised by the type of aggregate or cement utilised, by the specific attributes it manifests, or via the approaches made use of to supply it.
