Abstract

Nowadays, concrete roll is used in various fields of civil engineering and architecture. Therefore, improving the mechanical properties of this product is important in order to increase the scope of its using. In this study, the effect of yarn and weave of 3-D spacer fabric was investigated on flexural and tensile strengths of concrete roll. For this purpose, four samples of 3-D spacer fabrics with different yarns and weaves were prepared and the cement was injected into these samples. After hydration of concrete roll, the initial cracking stress, final stress and tensile strength were obtained. The results showed that the number of spacer yarns has a significant effect on the amount of initial cracking stress, and the final stress of flexural strength is also increased almost with increasing the initial cracking stress. The results also showed that the type of yarn used in the 3-D spacer fabric has a significant effect on the tensile strength. The tensile strength of concrete roll is increased with increasing the capillary ability of the samples, due to the better hydration of concrete.
