When selecting aggregates for a project, there are many properties that you should know about so that you choose the right product. The success of your projects depends on working with an experienced provider of aggregates that will ensure your delivery adheres to the classification properties you need. Here are just a few of the properties to consider:
- Size and shape – You will need to ascertain whether you need fine or coarse aggregates for your project as this decision impacts the durability and strength of the concrete. In addition, be sure the shape doesn’t increase voids or reduce bondage that could increase your costs and reduce the strength of your concrete.
- Texture – Aggregates that are rough in texture will bond better than those that are smooth.
- Water absorption – Be sure to know the water absorption ratio between dry and saturated weight so you can utilize the right water to cement ratio.
- Porosity – Choose aggregates with low porosity so they will not disintegrate under a load.
- Composition – Testing for chemical particles should be done to be sure they will not react with the cement, resulting in cracks.
- Compressive strength – It is critical that the aggregates you use for concrete work have the appropriate crushing value or your structure will not have the overall strength desired.
It is clear that the quality and properties of aggregate are of extreme importance for any concrete project. Working with an aggregate supplier you can trust for quality materials that meet your minimum requirements is imperative if you are to satisfy the project’s needs and maintain the structural integrity expected.
