Abstract/Summary
Disposable face masks are one of many single use products that are detrimental to the environment. The construction industry has been introducing new ways to incorporate recycled products into their materials. This paper addresses one possible way to use more environmentally friendly materials in the construction industry. 16 concrete cylinders were prepared using 4x8 forms. The mix was manipulated to test the impact of incorporating varying levels of disposable shredded face masks. Compressive strength and workability were measured in these cylinders. Eight cylinders were prepared for the control batch. Four cylinders were prepared using 10 oz. of shredded face masks and four cylinders were prepared using 30 oz. of shredded face masks. The workability for all batches was tested on day one. The compressive strength testing occurred at seven days and 28 days after the cylinders were poured. Honeycombing can be seen on most of the cylinders that include shredded face masks. The addition of shredded face masks in to the concrete resulted in a decline in workability and compressive strength. This can be overcome by decreasing the amount of shredded face mask material in each batch. Introducing plasticizer will also help increase workability of the concrete containing shredded face mask.
