What is the most common factor causing problems with concrete during installation?

The most common factor causing problems with concrete during installation is too much water added to the mix. When excess water is introduced to the concrete mixture, it increases the water-cement ratio, which can lead to a weaker final product. This results in several issues, such as decreased strength, increased porosity, and greater susceptibility to cracking and other forms of damage.

A higher water content can cause the concrete to be too fluid, reducing its ability to hold its shape during curing and increasing the likelihood of segregation, where the aggregate sinks and the paste rises. Ultimately, this compromises the overall structural integrity of the concrete. Proper mixing and the correct water-cement ratio are essential for ensuring the concrete achieves optimal performance in strength and durability.
