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 ...

Recycled concrete presents a higher porosity than traditional concrete, making it more susceptible to external agents and favoring the development of different pathologies in reinforced concrete structures. In particular, ...

The paper presents a methodology to model three-dimensional reinforced concrete members by means of embedded discontinuity elements based on the Continuum Strong Discontinuous Approach (CSDA). Mixture theory concepts are ...

Cracking is a common failure in concrete asphalt mixtures due to fatigue and low temperatures. For centuries fibers have been used to reinforce materials and short and long fibers have extensive use in Portland cement ...

The paper presents a new methodology to model material failure, in two-dimensional reinforced concrete members, using the Continuum Strong Discontinuity Approach (CSDA). The mixture theory is used as the methodological ...
