Vinasse is the main by-product of the sugar and alcohol industry. For each liter of ethanol produced from sugarcane, approximately 12–18 L of vinasse are generated. Being such, its use as a hydration agent in concretes may ...

This paper presents an experimental research on the use of eddy current testing (ECT) and artificial neural networks (ANNs) in order to identify the gauge and position of steel bars immersed in concrete structures. The ...

The purpose of this research was to determine the time-dependent behavior of high performance lightweight concrete and to examine how long-term behavior affects the prestress losses in high strength precast, prestressed ...

This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...

Two high-performance lightweight concrete (HPLC) mixtures with average compressive strengths of 68.5 and 75.4 MPa (9950 and 10,950 psi) were developed. Their air-dry unit weights were 1875 and 1905 kg/m(3) (117 and 119 ...
