There are several advantages of high performance concrete (HPC) application in building construction which are not achievable using conventional concrete. The strength, durability, resistance to ch
Types of Advance Cast-in-Place Concrete for Structure Repair Cast-In-Place Fiber-Reinforced Concrete When metallic or polymeric fibers (made up of steel, glass or synthetic and natural plastics) ar
Durable concrete construction requires selection of durable construction materials. Selection and properties of these construction materials are discussed.
Freezing reduces strength of concrete by 20 to 40 % when fresh concrete is subjected to freezing. Antifreeze admixtures of concrete, its properties and uses in cold weather concreting are discussed
Alkali aggregate reactions (AAR) occur when aggregates in concrete react with the alkali hydroxides in concrete producing a hygroscopic gel which, in the presence of moisture, absorbs water and cau
Alkali-activated concrete (AAC) is defined as a class of cement-free concrete that is an alternative to Portland cement concrete (PCC). In AAC, the cement is entirely replaced by an alternative bin
Air-entrained portland cement is a special cement which has air bubbles introduced in the cement or concrete that provides the space for expansion of minute droplets of waters in the concrete due t
Measurement of Air Content in Concrete Air content of concrete is measured by the pressure air measurement method which is based on the principles of The Boyle’s law. The Boyle’s law st
The purchase of land is arguably the most consequential financial decision a home builder can make. The amount paid for a lot directly determines the profit margin available on every home built on that land, and paying too much creates a financial hole that is extremely difficult to escape. Industry benchmarks indicate that the cost
Identifying and Sealing Major Thermal Bypasses: Essential Guide for Energy-Efficient Homes Thermal bypasses are unintended pathways in the building envelope that allow heat to bypass the insulation layer, dramatically reducing the effectiveness of the building’s thermal control. While many homeowners focus on sealing small cracks around windows and doors, the largest energy losses in most
