Buy Quality Aggregate Supplies from Natural and Recycled Sources
Aggregates are the key ingredients used to produce concrete, along with Portland cement and water. Aggregates are commonly known as inert granular materials, and may actually refer to sand, crushed stone, or gravel.
In order to achieve a good mix, aggregates should be hard, clean, durable particles free of other coatings, chemicals, and fine materials that could deteriorate the concrete. Natural sand and gravel are usually sourced from seabeds, lakes, rivers, or pits. Crushed aggregates are obtained by crushing large gravel, cobbles, boulders, or quarry rock. Once harvested, the aggregate is crushed, analysed, and washed to achieve an ideal gradation and level of cleanliness, and then stored properly to reduce degradation, and avoid contamination.
Understanding the Particularities of Different Kinds of Aggregates
When buying aggregate and gravel supplies, contractor’s judge these products based on several key characteristics, including abrasion and skid resistance, grading, durability, surface texture, and particle shape.

Natural variations – blue metal supply, for instance, known for their specific blue colour, are sourced from Sydney-based quarries – can be quite pricy, considering the reduced local supply linked to years of continuous extraction, and the widespread utilisation of ready-mix concrete. Even though blue metal is expansive, it is still used by plumbers to place around sewerage pipes, due to Sydney Water regulations not allowing the use of recycled aggregates in this situation.
