In new houses or large home extensions, raft slabs are used in the foundations. Concrete beams are laid down in both directions, along with steel reinforcing to further strengthen a new slab, then the main pour is done. Beams that are placed on the edges of a raft slab are known as ‘Edge Beams’ when... Read MoreWhat is a raft slab?

It means a particular grade of concrete, that is has been left to cure for a full 28 days. After this time it will have an overall compression strength of 25 N/mm – which is where the m25 comes from. Visit: https://www.concretersperth.com/ Read MoreWhat does m25 mean for concrete?
Also known as “concreter finishers” usually a person that works with concrete is called a ‘concreter’. Even someone that only pumps concrete, and not do any of the surface smoothing or stencilling, is still referred to as a ’concreter.’ Visit: https://www.concretersperth.com/ Read MoreWhat is a concrete worker called?
If rain, hail or snow is predicted, concrete needs to be protected if it’s been freshly poured, or in early curing phase.

Concrete that has been cured will be strong, stable and resistant to cracks. If curing isn’t done then it will be weak, crack, split or even collapse under high compressed loads. It is crucial that time is allowed for curing during any concreting project, no matter how small. Visit: https://www.concretersperth.com Read MoreWhat happens if curing is not done?
To achieve the strongest, most durable concrete with the mix used, it needs to go through a curing stage. At least 7 days is needed for concrete to cure, although longer can be better if it’s able to be protected enough. Curing can be done in temps as low as 5º C.

In a concrete mix, the water amount added needs to be just right. If too much water goes in then the overall strength will be lower, with cracks and shrinkage. If not enough is added it will crumble and break. One of the most important things to be monitored, is how much water is going... Read MoreWhat happens if you add too much water to concrete?
