Polyethylene sheeting has been a staple of residential construction in cold climates for decades. Often referred to as the “poly vapor barrier,” this thin plastic membrane was widely installed on the interior side of exterior walls to control moisture movement. However, the role of polyethylene in modern building assemblies is more nuanced than many builders […]
Dry mix process and wet mix process are the two methods of shotcrete construction which are based on the time at which the water is added to the mortar or concrete mix. in Dry mix process, water is
Self-sensing concrete is a smart concrete technology that can sense the stress, strain, and damage in itself. It is also called as self-monitoring or piezoresistive or pressure-sensitive or intrins
Quality control of foam concrete is essential to obtain required properties of concrete mix. Applications of foamed concrete and its quality control is discussed in this article.
Introduction A water-resistive barrier (WRB) is one of the most important but often misunderstood components in modern wall assembly construction. Positioned behind the exterior cladding and over the sheathing, a WRB serves as the secondary line of defense against moisture intrusion, ensuring that any water that penetrates the siding drains away from the structure rather
What is Pumped Concrete? Pumped concrete is the concrete which is transported to heights by means of pumping using concrete pumps. This method is used where large quantity of concrete work is invol
What is pullout tests on hardened concrete? The fundamental principle behind pull out testing is that the test equipment designed to a specific geometry will produce results (pull-out forces) that
The protection of freshly placed concrete, especially in the first 12-24 hours after its placement, is critical. This is because of the initial setting phase of the concrete. If the concrete is not
Water intrusion is one of the most persistent threats to the durability of a building. Moisture that gets trapped inside wall assemblies can lead to rot, mold, reduced insulation performance, and costly structural damage. Over the past two decades, the building industry has moved far beyond basic felt paper to a diverse range of engineered
Water-resistive barriers (WRBs) are a critical component of any well-designed building envelope. Positioned behind the exterior cladding, these materials form the primary line of defense against moisture intrusion into the wall assembly. While the terms “weather-resistive barrier” and “water-resistive barrier” are often used interchangeably, building professionals increasingly prefer the more specific term WRB to emphasize
