Advantages and Disadvantages of Lightweight …

Lightweight concrete (foamed concrete, AAC, etc.) costs more to produce than traditional concrete, but it can save contractors more money in the long term. Learn more about the advantages and disadvantages of lightweight concrete.

Understanding Different Types of Lightweight …

Obviously, weight gains vary widely from product to product but the potential of “green” uses for by-product and recycled materials have become a focus for this type of aggregate. Cellular or Aerated Concrete. This type of lightweight concrete is the result not just of the product, but also of the process.

Lightweight Aggregate Concrete | ScienceDirect

Lightweight aggregate concrete differs from the normal weight concrete because of its porous nature and lower strength. This fact is reflected on most of the properties; for example, on physical and mechanical behaviors. Normally all concrete types are designed according to what concrete is sought.

PUMICE AGGREGATES FOR STRUCTURAL LIGHTWEIGHT AND ...

for producing structural lightweight and internally cured concretes. Mixture designs were developed for lightweight concrete containing both partially saturated and fully saturated pumice aggregates. A vacuum saturation system was developed to completely saturate the normally partially saturated aggregates and

The Pumice Store: Lightweight Concrete Aggregate

LIGHTWEIGHT CONCRETE AGGREGATE (CRAFT) Lightweight pumice aggregate for craft-type precast concrete projects—including statuary, containers, pavers—where a smaller aggregate size is desirable. NOTE: the addition of pumice pozzolan (a microfine powder) will provide additional density and strength to cast concrete as well as mitigate ASR.
