One amazing building product is concrete. Concrete is a mix of cement, sand, stone and water, and then mixed into a paste. Many people confuse the difference between cement and concrete, concrete is like a cake mix and cement is the flour. The Romans invented concrete over 2100 years ago; they revolutionized the building of large structures. Today’s advances in production processes and quality control of materials produce a better, stronger mix then back in the day. The alternate products other than straight portland cement create performance mixes the offer better finishing characteristics as well as the opportunity to use recycled products.
Two of the most common cementitious products are slag cement and fly ash. According to the Slag Cement Associations web site, slag cement has been used in concrete projects in the United States for over a century. The replacement of the typical cement with slag cement offers some different performance and finishing properties such as a lighter color, better workability, higher compressive and flexural strength and improved resistance to chemicals. The Portland Cement Association reveals that fly ash is a by-product of burning pulverized coal in electrical generation. It is unburned residue collected on mechanical or electrostatic separators. The material is processed into a powder and added to portland cement concrete. Fly ash has a retarding effect on the concrete mix and in large doses can increase set time as well as slow strength development.
The flexible uses of concrete make it a favorite for the new home building industry. The many area’s that concrete is used include the foundation, driveway, sidewalk, patio, roads and parking lots. Concrete is really somewhat irreplaceable in longevity and durability. Of course new homes have been built with wood foundations but were not accepted well in the Fort Wayne market. Walks, drives, and patios could be done with asphalt or pavers but for the most part concrete is the choice most of the time. For roads the concrete is the most durable but is more difficult to repair. Thank you for checking out my post, Matt Lancia Signature Homes.
