Streszczenie

Artykuł przedstawia wyniki badań próbek betono- wych, wykonanych w technologii druku 3D, mających na celu określenie wpływu efektywności zespolenia międzywarstwowe- go na właściwości mechaniczne próbek oraz mechanizmu ich zniszczenia (wykorzystano technikę tensometrii elektrooporowej oraz metodę cyfrowej korelacji obrazu (DIC)). Badania wyka- zały m.in., że ograniczenie pola sczepności międzywarstwowej doprowadziło do zredukowania wytrzymałości na zginanie o 37,4% oraz na rozłupywanie o 52,2%.

Abstract

The paper presents the results of testing 3D concrete samples, aimed at determining the impact of the effectiveness of interlayer bonding on the mechanical properties of the samples and the failure pattern (electrical resistivity strain gauge technique and digital image correlation (DIC) method were used). The tests showed that limiting the interlayer area led to a reduction in flexural strength by 37.4% and splitting strength by 52.2%.
