Sand is one of the most fundamental building materials used for a wide range of construction tasks, from concrete and mortar to foundations and pavings. Its versatility makes it an excellent choice for builders, landscapers and DIY enthusiasts alike. However, not all sand is the same. There are many different types of building sand, each with different characteristics that make them suited for different applications.
In this blog post, we will explore the various types of sand used in the construction industry, their characteristics, and the specific applications where they are most suited.
Building Sand
Building sand is the most basic form of building aggregate, which is commonly used for a number of general construction tasks, like bricklaying and plastering. Its fine, smooth grains make it ideal for cement, creating a mortar that offers a strong bond between bricks. Building sand is often used for general levelling work and minor construction repairs, making it a versatile sand that many builders and contractors like to keep on hand.
Sharp Sand
Sharp sand is a general-purpose sand that has larger grains with a coarser texture than building sand. That makes it particularly well suited for mixing concrete, as the rough edges of the grains help the cement bind together for a more durable mix. Its large grains also make it well suited for laying paving slabs, requiring a dry mix mortar, which provides high strength and low flexibility.
Ballast
Ballast is a mixture of sand and gravel that is commonly used for building foundations and load-bearing structures. It provides a stable base that is strong enough to support heavy loads while still enabling water drainage. Its durability and water drainage properties make it an ideal aggregate for footpaths, roads and railway tracks, where long-term stability and effective drainage are needed.
Recycled Sand
Recycled sand is made from repurposed construction waste, making it a more eco-friendly alternative to primary aggregates. Recycled aggregates like sand are becoming increasingly popular as a way for construction companies to enhance the sustainability of their projects while keeping costs down. Despite being a recycled material, it can be used for a number of jobs, including mortar mixing and as a bedding layer for block paving and patios.
Reject Sand
Reject sand is a coarser byproduct of quarry processing that is often chosen as a low-cost alternative. While it is not suitable for fine mortar or concrete applications, it is frequently used for filling voids and trench backfilling due to its good compaction properties. Reject sand is also a highly practical aggregate for service ducting surround or as a base layer for slabs.
