Waterproof concrete mix –  An overview

Waterproof concrete mix – An overview

What is Waterproof Concrete Mix? Waterproof concrete mix is a type of concrete designed to be impervious to water and moisture. It is created by adding waterproofing admixtures to standard concrete mix during batching. These admixtures work by reducing the capillary flow of water through the concrete. When conventional concrete is exposed to water over…

10 Steps and Types of Slump in Concrete Test

10 Steps and Types of Slump in Concrete Test

The slump test concrete is a simple and commonly used method for measuring the consistency and workability of fresh concrete before it sets. Developed by Edgar D. Coolidge in 1918, the test is crucial for ensuring the concrete’s quality and its performance in construction. The process involves filling a cone-shaped mold with freshly mixed concrete,…

10 Remarkable Benefits of Grading of Coarse Aggregate in Concrete

10 Remarkable Benefits of Grading of Coarse Aggregate in Concrete

Graded coarse aggregate refers to the determination of the particle size distribution. They are sorted into groups by passing through a series of stacked sieves with progressively smaller mesh openings. The sieve sizes and percentage of aggregates falling into size fractions are key to the selection and performance of aggregates for different uses. Coarse aggregates…

4 Remarkable Benefits of Using Graded Aggregates in Construction Projects

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…

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

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 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…
