graded aggregates

4 Remarkable Benefits of Using Graded Aggregates in Construction Projects

Graded aggregates are aggregates that have been specifically sorted by size into appropriate classifications. The sorting of aggregates by size is known as grading. A well or properly graded aggregate will have a range of particle sizes that allow for strength, workability, and other properties needed for construction applications. Graded aggregates are used extensively in…

7-day concrete strength

Significance of 7-Day Concrete strength, Performance and Quality Control

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 Quality Control

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…

7 Powerful Protection Features of Hardened Concrete

7 Powerful Protection Features of Hardened Concrete

 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…

sieve shaker

Sieve Shaker – a Precision Screening Instrument 

Sieve shakers are devices designed to help promote particle movement through a stack of sieves, facilitating accurate particle separation. As the particle separate, they are retained on the various sieves depending on their size, providing insight into the average particle size of your sample. Sieve analysis is a long trusted method for accurately determining particle size…

concrete honeycombing repair

5 Concrete Honeycombing Repair and Detection Techniques

Concrete Honeycombing Repair is required to treat rough and stony surface that appears on concrete when there are air voids between the course and the aggregate. This happens when insufficient fine material gets into the concrete mixture due to poor mixing or incorrect aggregate grading When poured concrete does not completely fill the formwork, voids…
