The density of different types of lime

The apparent density of the two types of lime used for soil stabilisation are different: hydrated lime has a density of between 300 and 600 kg/m while quicklime is between 800 and 1200 kg/m. These different densities determine both their transportation – depending on the cargo capacity of the tanker, the amount of product shipped can vary, depending on its nature – and the dosing operations on site. The dosing factor needs to be altered (by a factor of 1.32) to go from slaked lime to quicklime (divide by the factor).

 
 
 

Packaging and transport of lime

The transport of lime, being a powdery product, should be done by tanker trailers connected to cab. Only for small operations or where the environment is a factor (farm or forest roads and tracks) is it advisable to use packaging such as sacks and big-bags.

Lime on site

Once the lime has been taken to the site, the product should be transferred to the spreader units. The product is unloaded by compressed air pressure.
In some cases, the use of silos or supply tankers on site may be advisable to regulate any possible incidents relating to the transport and spreading of lime.The implications in work prouctivity of bad weather conditions will be minimized by the use of these tanker.
The success of a supply operation is based on optimum coordination between the supplier and the people in charge of receiving the shipment on site.
