Qayta ishlangan polikarbonatning morfologik xarakteristikalari silindrsimon zarrachalarni 
aniqlandi, ularning o'lchamlari 1,5 mm dan 3,0 mm gacha, silliq va porloq sirt, shuningdek, qo'pol 
tuzilishga ega; bunday xususiyatlar polikarbonatni betonga aralashtirish uchun javob beradi.

stokiometriyasini taklif qiladigan EDS tomonidan tasdiqlangan.
Bundan tashqari, chiqindi polikarbonatning funktsional guruhlari FT-IR spektroskopiyasi 
orqali aniqlandi. Kutilganidek, bosim kuchi qiymatlari va betonning muvozanat zichligi 
polikarbonat zarrachalarining o'lchamlari va uning konsentratsiyasiga bog'liq; eng yuqori bosim 
kuchi qiymatlari 3% kichikroq zarralar bo'lgan beton uchun olingan, bu qiymatlar polikarbonat 
zarralari bo'lmagan betonga nisbatan 20% yuqori edi. 
Kichikroq polikarbonat zarrachalari betonda kamroq bo'sh joy yaratadi va natijada bosim 
kuchi oshadi. Bundan tashqari, qayta ishlangan polikarbonat konsentratsiyasi oshganda, betonning 
muvozanat zichligi zarracha o'lchamidan qat'i nazar, pasayadi. Polikarbonatli beton ACI 213R 
standartiga mos kelishi istiqbolli.
