5 Common Mistakes to Avoid While Using Ready-Mix Concrete

Ready-mix concrete is a popular choice in modern construction because it saves time, ensures quality, and is easy to use. However, many people unknowingly make mistakes while handling or using it. These mistakes can lead to cracks, poor strength, or even damage to the structure.

In this blog, we’ll discuss the 5 most common mistakes to avoid while using ready-mix concrete to ensure a strong and durable construction.

1. Wrong Concrete Mix Selection

One of the biggest mistakes is choosing the wrong mix grade for your project. Ready-mix concrete comes in various grades (like M20, M25, M30, etc.) based on the required strength.

🔹 Solution:
Always consult with your civil engineer or supplier to choose the right mix based on your structure type-be it a foundation, column, slab, or road.

2. Delays in Pouring Concrete

Ready-mix concrete must be used within a certain timeframe (usually 90 minutes) after it's mixed. Delaying the pour can cause it to set early, which affects the strength and bonding.

🔹 Solution:
Plan your worksite in advance. Make sure the workers and tools are ready before the truck arrives so the concrete can be poured without delay.

3. Poor Site Preparation

If the surface isn’t properly cleaned or leveled, the concrete might not set evenly. Also, debris and dust can reduce the bonding between the concrete and the base.

🔹 Solution:
Clean the site thoroughly and prepare the formwork and reinforcement as per the design to avoid wastage and weak structure.

4. Improper Curing

Curing is a critical step after concrete is poured. Not curing properly or stopping it too soon can lead to cracks and low strength.

🔹 Solution:
Cure the concrete surface with water or a curing compound regularly for at least 7 days (preferably 14 days) to ensure durability.

5. Ignoring Weather Conditions

Hot weather can cause the concrete to dry too fast, while rain can dilute the mix. Both can lead to poor quality and weak results.

🔹 Solution:
In hot conditions, cover the area with wet burlap or use a curing compound. In rainy weather, protect the poured concrete with waterproof sheets or delay the pour if needed.

Final Words

ready-mix concrete can make construction faster and more efficient, but only when used correctly. By avoiding these 5 common mistakes, you can ensure a longer-lasting and high-quality structure.

• Always work with a reliable ready-mix concrete supplier.
• Follow best practices for mixing, pouring, and curing.

FAQs

Q1. What is the ideal Time To Use Ready-mix Concrete After Delivery?
A: Ideally within 90 minutes of mixing, but this can vary slightly based on temperature and mix type.

Q2. Can Rain Affect Freshly Poured Concrete?
A: Yes, rain can weaken the surface and disturb the setting. Always cover it properly during rain.

Q3. Why is Curing Important After Using Ready-mix Concrete?
A: Curing helps the concrete gain strength and prevents cracks by maintaining moisture content.
