When working with ready mixed concrete, avoiding common mistakes is crucial to ensuring the integrity, durability, and aesthetic quality of your project. Below are some of the most frequent pitfalls encountered in handling and applying ready mixed concrete, along with strategies to avoid them.
Site Preparation
One of the most common mistakes is poor site preparation. Before the concrete arrives, ensure the site is properly graded, compacted, and free from debris. Inadequate preparation can lead to uneven surfaces, cracking, and an unstable foundation.
Proper Formwork
Incorrect or inadequate formwork can lead to concrete leaks, bulging, or misalignment. Forms should be rigid, watertight, and anchored securely to withstand the pressure of fresh concrete.
Weather Considerations
Ignoring weather conditions can have serious implications. High temperatures can lead to rapid moisture evaporation, causing cracks, while low temperatures can slow curing and lead to freeze-thaw damage. Plan your pour according to the weather forecast and take necessary precautions, such as using curing blankets or windbreaks.
Incorrect Water Ratio
Adding too much water to the mix is a common error that can compromise the strength and durability of the concrete. It’s vital to adhere to the water-to-cement ratio specified by the manufacturer to maintain the desired properties of the concrete.
Delayed Delivery or Placement
If there are delays between mixing and placing, the concrete may begin to set, making it difficult to work with and potentially affecting its structural integrity. Ensure that your schedule is well-coordinated to minimise any delays, and have a contingency plan in case of unexpected hold-ups.
Improper Mixing at Site
Though ready mixed concrete is prepared off-site, it may require mixing at the site to adjust consistency. Over-mixing or under-mixing can lead to segregation of the aggregates or inconsistent texture. Follow the manufacturer’s guidelines for any on-site adjustments.
Insufficient Compaction
Failing to adequately compact the concrete can result in air pockets and a weaker structure. Use appropriate tools like vibrators to ensure proper compaction, particularly in areas with complex forms or reinforcements.
Incorrect Layering
Pouring concrete in layers that are too thick can prevent proper curing and create weak points. For thick sections, pour in manageable layers and allow adequate time for each layer to settle before adding the next.
Overworking the Surface
Excessive troweling or finishing can cause the concrete to become too smooth, leading to a weak surface prone to cracking and dusting. It’s important to achieve the right balance between enough finishing to ensure a flat, even surface and overworking it.
Improper Curing
Curing is a critical phase in the concrete process that is often neglected. Concrete needs adequate moisture over time to develop its full strength. Use curing compounds, water-retaining covers, or continuous water applications to ensure proper curing.
Rushing the Process
Attempting to accelerate the curing process can lead to structural deficiencies. It’s crucial to respect the setting time specified by the concrete supplier and avoid any interventions that could disrupt the curing process.
Delayed Finishing
On the other hand, waiting too long before finishing the surface can make the concrete difficult to work with. Determine the right time to start finishing by testing the concrete’s surface for readiness—when it can support foot pressure without significant indentation.
