                     What is gravel and how is it used in construction? 
 
 
Gravel is a mixture of small stones, crushed rock, and pebbles used in construction. It is 
important because it improves the strength, stability, and drainage of a structure. Gravel is 
available in different sizes, and the correct size depends on the type of construction work. 
Gravel is commonly used in concrete. When mixed with cement and sand, it forms strong 
concrete for foundations, slabs, columns, and beams. It is also placed below roads, 
pavements, and foundations to improve support and prevent water from collecting under the 
structure.  
This helps reduce the chances of settlement and cracks.There are different types of gravel 
used in construction, such as crushed stone gravel, river gravel, and pea gravel. Crushed 
stone gravel is most commonly used because it provides better bonding with cement. 
Choosing the right type and size of gravel is important for making construction work 
stronger, safer, and more durable.
