If you’re planning a building or landscaping project this summer that involves paving, there’s more to the process than just mixing and pouring the material. Incorrectly prepared concrete is subject to numerous problems — especially in the heat. Here, you’ll learn how you can avoid some of the most common pitfalls.
Segregation is when the different particles in your concrete mix — such as gravel, sand, and cement — begin to separate into different sections or layers based on their size and density. If you lay segregated concrete, it will create regions of various textures on the surface of your slab — and you’ll also have some sections which shrink more than others, weakening the slab structure overall.
To avoid segregation, resist the urge to mix your concrete for too long. More stirring won’t even out the mixture; it will cause it to separate further. Mix until the components are combined, then pour your concrete quickly to avoid settling.
Also called chalking, this is the formation of a layer of fine cement dust on top of your slab. Dusting occurs due to traffic when the cement is weak — and weak cement is most often due to excessive water in the mixture.
When you mix your concrete, use as little water as possible. The resulting mixture will be thicker and less workable; but, when it hardens, it will be significantly stronger than a mixture with more water content. If you’re worried about getting the proportions right, order a delivery of ready-mix concrete from a local supplier.
