Concrete blocks are available in different forms to be used as construction material, such as
- Solid concrete blocks
- Hollow concrete blocks
- Solid & hollow light weight concrete blocks
- Autoclave aerated concrete blocks
- Concrete stone masonry blocks
While storing these concrete blocks at site, following guidelines should be followed.
Guidelines to Follow While Storing Blocks on Site
- Do not dump concrete blocks at site.
- Store the blocks close to the site of work so that least effort is required for their transportation.
- Unload one block at a time and stack it in regular tiers to minimize breakage and defacement.
- The height of the stack should not be more than 1.2 m. the length of the stack should not be more than 3 m. and width of the stack should not be more than 2 to 3 blocks.
- If blocks are cured for less than 28 days, then stack these blocks separately.
Note: Generally all blocks should be water cured for 10 to 14 days and air cured for another 15 days; thus no blocks with less than 28 days of curing is used in building construction.
- If blocks are manufactured at site, then mention date of manufacture of the blocks on the stack of blocks.
