• To increase plasticity and water-retentivity

What is the main component of lime mortar?

• Sand

• Cement

• Lime

• Water

What is the function of a plasticizer in concrete or mortar mix?

• Increase free-alkali content

• Make the mix workable with little water

• Increase compressive strength

• Reduce plasticity

What is the recommended use for Type O mortar?

• Foundation walls

• Exposed masonry above grade

• Interior non-load-bearing walls
