4 Common Factors Which Impact The Workability Of Concrete

Almost every construction activity requires concrete as it has become common building material. It acts as a binder which sets, hardens and binds with other materials. Concrete is often considered to be the best construction material because of its workability.

For someone not aware of the term, workability means the ease of concrete placement. It is a vital property of fresh and raw concrete. You will be surprised to know that every material and process used during the mixing can impact its workability.

Why Builders Prefer Concrete With More Workability?

Builders all over the world prefer concrete with more workability as they can be mixed and transported to construction sites with ease. You can even place them in forms and compact them according to your project requirement. It is easy for construction workers to work with highly workable concrete. No wonder, the demand for ready mix concrete in Surrey is always quite high. It is mixed off-site according to the client’s exact specifications before being delivered to the construction site. The primary advantage of using ready mix concrete is that it saves time for your business and your construction work is completed faster.

Few Factors Which Impact The Workability Of Concrete In Surrey

Cement Content
Since the cement is a very vital material used to make concrete, it can impact its workability. If you want to fill the space between the aggregates easily, use more cement to prepare the concrete and use the paste to coat the aggregates. The friction between the aggregates will reduce and they can move smoothly while you are mixing, transporting, placing or compacting the concrete. Experienced suppliers know the right water-cement ratio and maintain it.

Water Content Of Concrete
The amount of water used to prepare concrete will also impact its workability. If you are looking for good workable concrete, try to maintain the water-cement ratio of 0.45 to 0.6. Avoid using any admixture. If the water/cement ratio is high, you can pour more water when preparing it. Choose concrete with a higher water/ cement ratio if you are planning to mix it manually. More water will make the mixing process easy.

Mix Proportions Of Concrete
Mix Proportions of Concrete refers to the ratio of coarse aggregates and fine aggregates with reference to the amount of cement used. It will become richer if you use more cement. The lubrication of aggregates will also increase and their flow will improve. Less paste will be available for the aggregates and their mobility will restrain if there is a low quantity of cement with reference to the aggregates.
Size Of Aggregates

Consider the size of aggregates used as it impacts the surface area of the aggregates. The surface will be less if the size of the aggregates is large. You will require more cement if the surface area increases as you will need them more paste to cover up the surface of the aggregates. You will also have to add more water to the mix to lubricate the aggregates.
Since you are aware of the common factors which impact the workability of concrete, it’s time you start looking for a reputed supplier.
