LoCem HLM - Low Carbon Lime Mortar - Masonry Void Infill Lime Mortar

An alkali-activated cementitious material that is lime-based with low compressive strength for use as an infill mortar for transitional steel frame buildings. In its dry form it is an off-white powder containing alkalis and mixes with water to harden as an off-white/ light grey mortar.

LoCem® HLM should be mixed thoroughly with an efficient shear mixer and placed with suitable equipment e.g. pressure pot or helical screw units. Water for mixing the powder should be clean and comply with the requirements of BS EN 1008.

Features and benefits:

• Single component mix.
• Density of 1435 kg/m³: 20 kg will yield 0.014 m³ litres of mortar infill.
• AACM geopolymer lime-based powder.
• Low carbon sustainable material, factory-blended from industrial waste by-products.
• Maximum aggregate size 3 mm.
• Ultra-low compressive strengths (BS 1881) of 1.0-1.5 MPa (seven days) and up to 3 MPa (28 days).
• Initial set time, to BS EN 196: 2 hours; final set time, to BS EN 196: 24 hours.
• All LoCem® products are factory-blended at ambient conditions. They are tested and packaged to quality control
• procedures in accordance with BS EN ISO 9001:2015.
• It is compatible with LoCem® +point® anode mortar for use within the fabric of such buildings for impressed current cathodic protection of structural steel.

Note: compressive strength development, workability and setting times are dependent on temperature and water content. This can be controlled with C-Probe retarders if necessary. Higher or lower temperatures will result in reduced or extended setting times, respectively.
