In the world of construction, the term “cold joint” refers to a discontinuity in a concrete structure that occurs when one batch of concrete hardens before the next batch is placed, resulting in a weak bond between the layers. This can compromise the structural integrity, durability, and aesthetic quality of the concrete element. Understanding cold … Read more
Concrete is the backbone of modern construction, with versatility that spans across everything from skyscrapers to residential projects. Traditional wet concrete mixtures are often the go-to for builders, but an alternative, dry concrete, is gaining attention in certain applications. Dry concrete refers to a concrete mix with little or no water added during batching, allowing … Read more
Low-slump concrete, known for its high strength and durability, has become essential in various applications requiring reduced fluidity, such as highway pavements, structural elements, and pre-cast products. Unlike conventional concrete, low-slump concrete minimizes water content while maintaining workability, reducing the risk of shrinkage, cracking, and segregation. Below is an exploration of the essential practices that … Read more
Calculating the correct amount of ready-mixed concrete to be delivered to a construction site is essential for maintaining project efficiency, cost control, and ensuring adequate supply. Suppliers use precise methods to calculate the yardage or volume required based on project specifications, and this article dives into these techniques. Understanding how suppliers calculate concrete yardage can … Read more
When fresh concrete is poured onto an existing hardened concrete surface, the bond between the two layers is critical to ensure structural integrity and prevent delamination or cracking. This article will guide you through best practices to create effective adherence between fresh and old concrete. 1. Understanding the Challenges of Bonding Fresh and Old Concrete … Read more
How is Concrete Affected by Being Dropped Vertically? Concrete is a widely used construction material known for its strength, durability, and adaptability. However, like all materials, its quality and performance can be compromised if it isn’t handled properly during the placement process. One such scenario is when concrete is dropped vertically from significant heights. This … Read more
Concrete technology is the study and application of the properties, behavior, and usage of concrete in construction. Concrete is one of the most commonly used construction materials worldwide, known for its versatility, durability, and relatively low cost. This field encompasses everything from the ingredients that go into making concrete, to the methods used for mixing, … Read more
Concrete is a versatile construction material used globally for various projects, from infrastructure to residential buildings. Its success in any project depends on proper handling, especially when it comes to timing. One critical aspect is the time concrete can be left in a hopper or barrow before being placed into formwork. This article will explore … Read more
In construction, concrete test cylinders are a widely accepted method for assessing the quality of concrete, particularly its compressive strength. These cylinders are cast under controlled laboratory conditions and are tested at specific intervals, such as 7, 14, or 28 days, to determine the strength of the concrete mix. However, the real question that engineers, … Read more
Achieving high-quality exterior concrete finishing requires attention to detail, the right mix, and proper execution during the construction process. Concrete is renowned for its strength and durability, making it a go-to material for outdoor structures such as patios, driveways, sidewalks, and facades. However, its aesthetic and functional qualities depend heavily on how it is finished. … Read more
