Disposable diapers, which everyone throws away after use for hygienic reasons, they can get a second life. This has been verified by a study that suggests soThis material can replace part of the sand in concrete and mortar in construction..
A research team from Japan’s Kitakyushu University has already built a 36-square-meter house, partly with previously disinfected used diapers.
That explains the study, published in the journal Scientific Reports up to 8% of sand for concrete and mortar could be replaced with disposable diapers used crushed without significantly reducing drag. It is an alternative to low-cost housing materials in low- and middle-income countries.
The reason is that disposable diapers are often made from wood pulp, cotton, viscose rayon and plastics such as polyester, polyethylene and polypropylene, and then go to the landfill where they are incinerated or landfilled.
But those same materials can be combined to form the sand needed for concrete.
The researchers prepared concrete and mortar samples by combining washed, dried and crushed disposable diaper waste with cement, sand, gravel and water, which were allowed to cure for 28 days.
They then tested six samples with varying amounts of diaper waste to measure how much pressure they could tolerate without tearing.
As a result, diaper waste could replace up to 10% of the sand needed for the concrete used to form columns and beams in a three-story house.
That ratio rose to 27 percent of the sand needed for concrete columns and beams in a single-story home, the publication notes.
