high early strength concrete mix is ideal for projects that require a faster curing time. This type of concrete is best suited for situations where road and structure repairs need to be completed quickly or when weather conditions prevent the normal curing process from occurring.
This type of concrete can be produced using a combination of techniques and ingredients. The main ingredients include a higher cement content, special cements such as Type III, and select chemical admixtures to improve the water/cement ratio. Adding a low range water reducer, such as a superplasticizer or a concrete set accelerator, to the concrete can also help increase its strength and speed up the curing process.
A recent study found that concrete made with a blend of high quality aggregates and high performance cement achieved a very rapid curing rate. This type of concrete was able to reach a minimum adequate compressive strength in just one day, which is considerably quicker than the 14 days required by regular concrete.
A high-strength concrete is made from a combination of coarse and fine aggregate, cement, a non-chloride water reducer, a concrete set accelerator and fiber reinforcement. The purpose of this article is to test the effects of a non-chloride hardening accelerator with additions of alccofine on the early age strength and durability of concrete. It also discusses how the use of this material can potentially allow for a significant reduction in the overall cost of concrete and provide greater environmental benefits.
