As early as 4000 BC the ancient Egyptians used quicklime, after mixing it with water, as a construction material for building pyramids. Today, quicklime is a widely used chemical compound. The use of lime surrounds our everyday life making the water we drink safe, the air we breathe cleaner, our steel purer and construction projects more stable. It goes into glass production, paper manufacturing, agricultural practices, chemical processes, plaster, mortar and other building materials, to name a few.
In construction applications, lime and lime-based reagents can dry wet soils to eliminate downtime, increase productivity and keep projects moving. They quickly modify weak soils to make work cleaner, safer, faster and easier. Soil modification provides an improved working platform that keeps materials coming to the job site. Lime derived products can also be used to stabilize soils providing long term, permanent strength gains. These strength gains can result in a thinner pavement layer if considered in the design saving contractors money and allowing DOT’s, General Contractors and Project owners to use funds elsewhere.
In environmental remediation applications, lime and lime-based reagents dry, solidify and fixate hazardous & non-hazardous waste streams. They adjust pH to grip heavy metals, reducing solubility. Lime derived products develop a pozzolanic matrix that prevents the mobility of metals and high pH adjustment grips heavy metals reducing solubility. Waste streams can be dried and strengthened using lime products to meet landfill (RCRA) requirements for landfill disposal.
