Why is it Necessary to Implement Drying Methods to Increase Concrete Slab Drying Time?

Water is one of the most essential elements required by concrete to achieve optimal strength. However, it becomes a nuisance if it remains in the structure after the curing period.If you intend to achieve your deadlines and save your project from extra costs and mould growth, then you should avoid prolonged drying times.

You can reduce the concrete slab drying time by developing dehumidification conditions on your site by hiring drying and dehumidification equipment from Cross Hire. But first, let us enlighten you about the optimal curing and drying times and what happens to concrete slabs if they are subjected to humidity after curing.

What are Suitable Concrete Curing and Drying Times?

Curing is necessary for concrete to achieve the required moisture content and temperatureso that it can acquire the necessary strength. By required moisture content, we mean that the relative humidity of concrete should be greater than 80%. Similarly, its temperature should be between 10̊ C and 32̊ C in case of conventional curing practices. However, if you are using low-steam curing methods, then you can let this temperature reach up to 60 ̊ C. These conditions are usually maintained over a span of 3 to 14 days, depending upon the strength and design requirements. Curing promotes the chemical activitiesthat cause the fine and coarse aggregates, admixtures and cement to bind into hardened concrete of required strength.

Once the curing period ends, the drying procedure starts during which the water content present on the concrete’s surface is removed. It is commonly observed on the construction sites that the curing procedure of slabs is way easier than the drying process. This happens because the workers fail to remove the humidity present on site. This causes delays in the elimination of water from the slab’s surface and gives rise to multiple issues such as lags.

There are multiple other factors as well that influence the concrete slab drying times such as cement type, water-cement ratio, type of curing compound used, slab thickness and aggregate type and amount.

Adverse Effects of Prolonged Drying Times

Are your concrete slabs facing the issue of prolonged drying times? Have you been ignoring this issue? If yes, then the next few points will be an eye-opener for you as they contain the negative effects that this problem can have on your construction site and the project.

Delayed Construction Schedule

Most of the times, the construction of the remaining structure depends on the dryness level of the slabs. In such cases, Why Should You Use prolonged drying time hinders the construction of other elements and increases the overall construction time of the structure. As a result, the project fails to meet the deadlines and schedules are disrupted.

Increased Budget

The budget of a construction project is heavily dependent on its schedule. This is because the equipment is mostly rented and the workers get paid on a daily basis. Therefore, as the schedule stretches further, the cost of the project also increases. As mentioned above, the delays in concrete slab drying increase the project’s time, and this results in an increased budget.

Project Hold-ups

Sometimes, prolonged drying times can cause even greater problems such as hold-up of a certain activity or even the whole project. This is because the equipment owners have their own rental schedules, and if your equipment owner refuses to provide you with the equipment after your scheduled date,then you will be forced to hold the whole project on that specific activity.

Installation of Floors

Flooring installations require a relative humidity below 80%-75% to ensure proper application of flooring materials. It is also essential to prevent the flooring and the underlayment from expanding in the future. If your slab doesn’t dry on time, then your floor installation contractor won’t be able to perform his work as per the schedule. This will also cause delays and increase the budget.

Microbial Growth

Increased relative humidity levels, porous concrete and high temperatures provide a breeding ground for bacteria, moulds and other organisms. They feed on the dust, pollen, salts and other microorganism trapped in the concrete, release acids that deteriorate the bonds between construction materials and decrease the strength of the structure. Their presence and growth can also pose health threats and degrade air quality.
