Applications & Material Features
This product is suitable for a variety of professional applications, ranging from masonry to industrial processing. Common uses include:
- Incorporation into mortar and stucco mixes.
- Blending with Portland cement for masonry applications.
- Application in scratch and brown coats.
- Addition to Portland-cement concrete mixes.
- Fly ash treatment and wastewater treatment.
- Other industrial or agricultural processes where dolomitic hydrated lime is specified.
50 lb Hydrated Lime features a dry-hydrate form produced by the controlled hydration of dolomitic quicklime, yielding a dry powder containing Ca(OH)2 and Mg(OH)2. Consequently, this dolomitic hydrated lime contains a higher percentage of magnesium relative to high-calcium hydrated lime. It is processed to achieve the specific water-retention and air-entrainment characteristics required for Type S and Type SA product variants.
