Szukana fraza: [Abstract = "In this context, a comparative study was based on the valorisation of marble and ceramic waste as sand in sand concrete made from straw fibres. To carry out this study, we introduced these wastes at substitution rates of 10% and 20%, separated and mixed, and studied the development of the properties of these concretes \(density, workability, air content, compressive strength and bending tensile strength\) and their behaviour with respect to durability \(capillary and immersion absorption and chloride penetration\)."]
