What is low-chert aggregate and what benefits do they provide ...
Chert, which is found to some degree in most aggregate deposits used to produce concrete in Southeastern Wisconsin, is porous aggregate (sand, gravel, or crushed stone) with low-resistance to weathering. Chert can cause surface defects, known as "pop outs," in exterior concrete flatwork applications. Pop outs are indentations in a concrete slab surface created when porous aggregate picks up moisture, freezes, expands, and fractures, taking a portion of the concrete slab surface mortar with it.Learn More
Different Types & Sizes of Aggregate for Concrete ...
Aug 11, 2018 · Aggregates are one of the most important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 60 to 80 % of total volume of concrete. So, we can say that one should know definitely about the aggregates in depth to study more about concrete. Aggregate may be natural, manufactured or recycled.Learn More
Aggregate Concrete - an overview | ScienceDirect Topics
Preplaced-aggregate concrete is more resistive to shrinkage and creep than conventional concrete is. This is due to the aggregate. The net result is more protection against cracking. This type of concrete can be used on numerous types of structures. The cost involved with using preplaced-aggregate concrete is likely to be more, but it may be worth it in the long run.Learn More

One Thing: Aggregate Moisture Content Testing - NPCA
Monitor Moisture in Concrete Aggregates to Yield Reliable Results
Super dry aggregate piles act like a porous sponge when added into a wet concrete mixture. The air-filled pockets between the aggregates tend to take up water from the concrete paste mix, depleting the water available to allow the particles to slip past each other during mixing, pumping, pouring, placement, and finishing.Learn More
Aggregate in Concrete - The Concrete Network
Aggregates comprise as much as 60% to 80% of a typical concrete mix, so they must be properly selected to be durable, blended for optimum efficiency, and properly controlled to produce consistent concrete strength, workability, finishability, and durability (Photo 1).Learn More
Recycled Concrete Aggregate - an overview | ScienceDirect Topics
Aggregate composed of recycled concrete generally has a lower specific gravity and a higher absorption than conventional gravel aggregate. Lack of widespread reliable data on aggregate substitutes can hinder its use. Aggregate typically accounts for 70–80% of concrete volume.Learn More
