Lightweight Concrete vs. Normal Weight Concrete

By Jason Spangler in Lightweight Concrete Concrete Information & Knowledge Base | 17 Comments

Standard concrete mixes typically use crushed natural stone as the coarse aggregate in the mix (along with Portland cement, water and sand). The actual weight may vary slightly according to local stone availability, but generally natural stone is relatively dense for its size, adding to the weight of the concrete mix. (This also adds to increased transportation and equipment costs.)

6 Outside Sources for Concrete Moisture

By Jason Spangler in Troubleshooting Floor Failures Concrete Information & Knowledge Base | 10 Comments

Concrete, like the majority of building materials, constantly interacts with the conditions around it. Temperature, humidity, and other factors all have an impact on the internal moisture levels in concrete – even when it has been deemed “dry” or has been successfully finished with a flooring or sealant. Problems can occur when external sources of […]

What Is Kiln Drying? The Reasoning Behind Drying Wood

By Tony Morgan in Forest Products Industry Information for Lumber Companies & Kiln Dryers | 36 Comments

Kiln drying is a standard practice in wood production mills and serves to efficiently bring green lumber moisture levels down to “workable” range–moisture content levels that will not end in the myriad of problems that can be caused by excess moisture levels in wood. These problems include warping and twisting in dimensional lumber, binding or […]

Managing Moisture Between the Flooring and the Concrete Slab

By Jason Spangler in Subfloor Moisture Concrete Information & Knowledge Base | 132 Comments

Water is an inherent part of the hydration process of concrete. However, allowing excess moisture to leave the slab after it’s poured is crucial to a successful flooring installation. Once the slab is poured, the excess moisture must leave the slab in order to strengthen the concrete bond. The slab must also dry to a […]
