The answer to this question is that it is a mix that hardens faster and gains strength sooner than normal mixes. This is a chemical process that happens when cement and water combine. Normally this process takes years to happen.
There are a few ways that you can make your concrete mix high early strength, including accelerating the chemical admixtures and using a low water to cementing material ratio by mass. During the hardening phase, it also helps to use steam from an autoclave curing machine.
The main advantage of using high-strength concrete is that it can carry loads that conventional concrete cannot. This allows for a reduction in the overall weight of the structure and can lower the cost of the building.
The primary application of high-strength concrete is for structural supports that require a high level of load bearing capacity. These can include floors, walls, roofs, columns, piers, bridge abutments and decks among others.
The main disadvantages of using high-strength and rapid-strength concrete is that it is more expensive to make, more difficult to place and requires additional finishing to ensure its quality. Moreover, it is not as environmentally friendly as normal concrete. In addition, it may be difficult to transport, place and finish the concrete in a timely manner.
