What is builders lime and how is it different from other types of lime?
Builders lime, also known as hydraulic lime, is a type of lime that is derived from limestone and is used in a variety of construction applications. It is different from other types of lime, such as non-hydraulic lime, in that it can set underwater and is more durable and resistant to weathering. This makes it an ideal choice for use in applications where exposure to moisture is a concern, such as in foundation work, basements, and exterior plastering.
The unique properties of builders lime are due to the presence of impurities, such as clay and silica, which are naturally present in the limestone from which it is derived. These impurities react with water to form a hard, compact cement that is capable of withstanding significant stress and strain. In contrast, non-hydraulic lime is derived from pure limestone and does not contain these impurities, making it less durable and more prone to erosion. As a result, builders lime is generally preferred for use in construction applications where strength and durability are critical.
What are the main applications of builders lime in construction?
Builders lime is a highly versatile material that can be used in a wide range of construction applications, including masonry, plastering, and rendering. It is often used to make mortar, which is used to bond bricks and stones together, and can also be used to create a hard, durable plaster that can be applied to walls and ceilings. Additionally, builders lime can be used to make a type of concrete that is similar to modern portland cement concrete, but has a more natural, breathable quality.
The use of builders lime in construction offers a number of benefits, including improved durability, reduced maintenance, and enhanced aesthetic appeal.
