Publication number: 20240051870Abstract: A mortar mixture reduces crack formation by using microfibers in pool plasters in order to increase flexural and compressive strength. A waterproof fiber reinforced mortar mixture reduces crack formation by increasing the flexural and compressive strength of pool plasters. By means of the fiber reinforced mortar mixture, workmanship errors (water added more than required due to weighing the material wrong, surface finishing, etc.) and adverse effects due to the external environment (extremely hot and/or windy weather) are minimized.Type: ApplicationFiled: November 5, 2021Publication date: February 15, 2024Applicant: KORDSA TEKNIK TEKSTIL A.S.Inventors: Burak ERDAL, Ugur ALPARSLAN
