Advantages and Disadvantages of Lightweight Concrete

Specific types of lightweight aggregates make varying forms of lightweight concrete. These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a grain of sand. This composition makes AAC highly suitable for pre-casting and reshaping.

aggregate size ranges between 1/4 and 5/16 in 5. Aggregate gradation is important for workability, compactibility and strength of concrete blocks. Fine-coarse aggregate blend is required to fill voids of concrete blocks not occupied by cement paste, thus, placing added significance to gradation. Furthermore, aggregate/cement ratio is adjusted so that adequate amount of cement paste coat
