They work by maintaining the heat of hydration in the early stages of the curing stages.

Using concrete blankets to speed up curingĬoncrete blankets are very successful when speeding up the curing process. Although accelerants will reduce the overall strength of the concrete upon completion, the difference in strength is not noticeable and will not affect its structural integrity. In some jobs where the concrete must be used as soon as possible, concrete contractors will use accelerants to speed up the setting time. Understanding how to mix concrete is essential in order for you to get the most out of it. Too much water will see the concrete cure too fast, resulting in poor overall structural integrity and strength, too little and the concrete will be much harder to work into place. Concrete needs the right amount of moisture in order to set at maximum strength. One of the most important factors to address in concrete hardening is the role moisture plays. Other factors that affect concrete setting time In turn, this makes the mix stronger, hardening as long as moisture is present (although, it is far slower). However, while concrete does continue hardening, it doesn’t necessarily benefit its structure, as it essentially becomes unnecessary.Ĭement and water are mixed together (along with aggregates) to form concrete and during this, the cement particles begin muxing with the water which forms bonds. While its optimum strength is known to peak roughly a month after its installation, concrete will continue to harden and develop as time goes on. However, concrete will continue curing for years

However, the concrete will only be at around 70-70% of its full strength, so driving heavy machinery on it is not advised during this time. You should be able to walk and perform normal tasks on concrete one week after its application. However, concrete reaches its full strength after approximately 25-28 days. In most cases, standard concrete (or full strength concrete) has a setting time of around one day, sometimes two days depending on the environment in which it is set.
