Carmeuse High Calcium Lime

Carmeuse’s High Calcium Lime Product Description

Carmeuse’s High Calcium Lime (Calcium Oxide) is produced from limestone containing over 98% calcium carbonate.

Made from high-quality, natural deposits of limestone, and meeting exacting chemical and physical properties, Carmeuse’s quicklime products provide high-performance, cost-effective, and environmentally friendly attributes and benefits for a broad range of industrial applications.

Carmeuse’s High Calcium Benefits and Uses

• Carmeuse High Calcium Lime is a hydrated lime that is typically used as an additive in type M, N, S, O, K mixes
• Can be slaked to create an aerial Lime Putty
• Carmeuse High Calcium Lime can be used to create interior plaster or to make an inexpensive whitewash
  • These are suitable applications for Carmeuse and can help cut the expense of NHL binders, however, performance data is not offered outside the known M,S,N,O,K criteria

The high calcium quicklime is produced by heating raw limestone deposits in a kiln up to temperatures of 900 degrees. This process is referred to as the “calcination process.”

High Calcium Lime products are often ground into a fine powder referred to as “Pulverized Quicklime” that is ideal for mixing with additives or other materials to result in specialized blended composites. Due to the chemical nature of some additives, the quicklime can become “Fluidized,” that is, having properties of being highly fluid. The fluidized quicklime is ideal for use with special material handling systems for optimum flowability and to avoid clogging.

Carmeuse’s High Calcium Application

Mist the substrate and any previous cement mortar application with water immediately before a new application but only as a slight dampening to control absorption. No standing water should remain during a new application. If any substrate is retaining inordinate amounts of moisture due to rising damp, bad flashing or moisture from a chimney cavity, this must be corrected before new work begins. ASTM has reports on normal absorption rates for most building materials not explicitly covered by individual manufacturers. Wait 24 hours between coats of stucco at 1:1:6 ratios.

Protect the new work for 24 hours from wind, direct sun,
freezing temperatures, excessive heat, and rain.
