Andhra Pradesh has a diverse range of sand types, primarily sourced from rivers, coastal areas, and manufactured sand (M-Sand). Here are the main types of sand available in the state:
1. River Sand
– Source: Extracted from major rivers like Krishna, Godavari, Penna, Tungabhadra, and Vamsadhara.
– Characteristics:
– Fine to medium grain size.
– Smooth texture, suitable for construction (concrete, plastering).
– Natural and widely preferred but regulated due to environmental concerns.

2. Manufactured Sand (M-Sand)
– Source: Produced by crushing granite or basalt rocks in crusher units.
– Characteristics:
– Coarser than river sand but better for strength in concrete.
– Eco-friendly alternative to river sand (reduces illegal mining).
– Used in RCC works and road construction.
3. Sea Sand (Coastal Sand)
– Source: Found along coastal districts like Visakhapatnam, Nellore, and Prakasam.
– Characteristics:
– High salinity content (requires washing before use).
– Used ma.jpg)
y for non-structural purposes like land reclamation and beach projects.
4. Filter Sand
– Source: Available near riverbeds and industrial suppliers.
– Characteristics:
– Coarse-grained with high silica content.
– Used in water filtration systems and industrial applications.
5. Silica Sand
– Source: Found in some districts like Nellore and Prakasam (used in glass manufacturing).
– Characteristics:
– High purity quartz content (>95% SiO₂).
– Used in glassmaking, foundries, and ceramics.
6. Pit Sand (Quarry Sand)
– Source: Mined from inland pits rather than rivers.
– Characteristics:
– Angular grains with good binding properties.
– Used for masonry work but less common than river sand or M-sand.
Regulation & Availability:
– The Andhra Pradesh government regulates sand mining through the AP Mineral Development Corporation (APMDC) to prevent illegal extraction.
– M-Sand is increasingly promoted as a sustainable alternative due to restrictions on river sand.
