This is a very important property that determines the performance and durability of concrete in construction projects. In particular, the 7-day of concrete strength is a key parameter that is often specified and tested to assess the early rate of concrete strength gain. Concrete gains strength over time through the process of hydration, whereby cement…
Air Meters for concrete measure the air content of fresh concrete in accordance with ASTM and AASHTO standards test methods. Gilson offers a selection of air meters for concrete for use in testing fresh concrete specimens or concrete mixes, lightweight aggregate concrete, or other lightweight mixes. Measuring the air content of fresh concrete is a critical…
Serving as robust structural supports worldwide, deep foundation pile systems allow transferring of superstructure loads through weak or unstable soils to reach stronger strata dozens of meters underground. From skyscrapers to offshore platforms, many ambitious building projects rely on piles extending deep into the earth. Engineers choose among numerous pile types and installation techniques like…
The Proctor test, also known as Proctor compaction test, is a long-established method for determining the optimum moisture content and maximum dry density of soils. This vital information allows assessment of a soil’s suitability for construction projects and helps establish the specifications needed to achieve the required strength and stability through engineered fill placement and…
An important physical property that engineers and contractors continually evaluate is the specific weight of concrete. Among the most pivotal properties specified for structural concrete is the all-important specific weight – measured as force per unit volume typically in pounds per cubic foot (lb/ft3). This specific weight of concrete quantifies the density of concrete once…
Hardened concrete refers to the state of concrete after it has undergone the curing process and has gained its desired strength and durability. Concrete is one of the most widely used building materials in the world, valued for its strength, durability, and versatility. However, concrete by itself is relatively brittle and prone to cracking under pressure or…
