Lightweight Concrete with Wastes Used for Hollow Concrete Blocks

In the article are presented the experimental and numerical researches on concrete blocks realized of green lightweight concrete. For preparing the hollow blocks the light weight concrete with wastes type chopped plastic bottles (PET), sawdust and fly ash was used. Experimental study on physical-mechanical and deformation characteristics of green lightweight concrete were done. The hollow blocks were tested in compression. Failure of blocks was ductile for both types of concrete, the blocks of lightweight concrete with saw dust presented a major degradation. The numerical analyses performed with ATENA software indicated a similar type of failure as that from the tests that indicates a good correlation of results.
