Blue Circle® X-Lime is a concentrated powder additive designed to improve the workability and water retention of cement-based mortars used in bricklaying and blocklaying applications. Suitable for use with General Purpose, Builders and Off White Cement, X-Lime helps simplify mortar production by combining multiple mortar-enhancing functions into a single product.
Improved Workability
Provides a smooth, easy-to-use mortar mix that is easier to spread and apply during bricklaying and blocklaying.
Enhanced Water Retention
Reduces water loss from mortar when laying clay bricks and masonry blocks, helping maintain bond strength and improving performance.
Replaces Multiple Additives
Can replace hydrated lime, air entraining agents and other mortar-enhancing additives, simplifying mortar production and material handling.

What is X-Lime?
Blue Circle® X-Lime is a concentrated mortar additive that combines air entraining and water retention properties in a single powdered product.
Many mortar mixes rely on hydrated lime, liquid air entraining agents, water retention additives or clay to improve workability and mortar performance, particularly when using sands with poor grading or particle shape. X-Lime is designed to replace these supplementary materials while helping produce a more workable and consistent mortar mix.
In bricklaying and blocklaying applications, masonry units absorb water from the mortar at the interface between the mortar and the brick or block. This can cause the mortar to dry prematurely and reduce bond strength. X-Lime contains water retention additives that help reduce moisture loss, while its air entraining properties improve mortar workability and handling characteristics.
As a guide, approximately 80g of X-Lime may be used per 20kg bag of cement, although dosage rates can be adjusted depending on sand quality and project requirements.
For convenience on site, one 2kg pail of X-Lime can be used with approximately 25 x 20kg bags of cement. Alternatively, 10kg of X-Lime can replace approximately 1000kg of hydrated lime, reducing material handling and storage requirements.
