G82-626 Air Properties: Temperature And Relative Humidity, David P. Shelton, Gerald R. Bodman
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes how to use a simplified psychrometric chart to better understand the relationships between air temperature and relative humidity.
Air is a vital component of our everyday lives. Air properties are important whether we are ventilating a livestock housing unit, drying grain, or determining relative humidity in the home. In a livestock building, temperature, moisture, odors, and toxic or noxious gases must be controlled. Since the moisture holding capacity of air increases with increasing temperature, heat may be added in grain drying to aid in removing moisture from the grain kernel. In the home, moisture can either be …

G82-623 An Overview Of Concrete As A Building Material, David P. Shelton, James M. Harper
University of Nebraska-Lincoln Extension: Historical Materials
The general properties of concrete are discussed, as well as its components and their proportions. Includes decisions customers should consider before using concrete.
Concrete, specifically portland cement concrete, has the qualities of strength, durability, versatility, and economy, and can be placed or molded into virtually any shape and reproduce any surface texture. It is the most widely used construction material in the world. In the United States almost twice as much portland cement concrete is used as all other construction materials combined.

G82-630 Concrete Construction: Obtaining Quality Results, David P. Shelton, James M. Harper
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes the prior planning, site preparation, forming, ordering, placing, finishing, jointing and curing needed for successful concrete construction projects, especially slabs or flatwork.
Concrete is an excellent construction material for many agricultural applications. By paying careful attention to some major considerations, quality concrete construction can be achieved. The result can be years of reliable service.
