ABSTRACT An anisotropic damage mechanics model is presented to describe the behavior and failure of concrete under biaxial fatigue loading. Utilizing the approach of bounding surfaces, the limit surface becomes a special case when the number of loading cycles is set to one. By increasing the number of loading cycles, the strength of concrete gradually decreases and the limit surface is allowed to contract and form new curves representing residual strengths. The magnitude of loading, load range, and the load path are known to influence the fatigue life a...

ABSTRACT Existence is concrete discerned bodily, thinking considers existents, and so concrete thinking is primal, at the base of logical thinking. Still, concrete actuality is reasonable beyond logical analysis. So, concrete thinking is “illogical” bodily reasonable. Thus this essay explores 1) concrete thinking various and 2) concrete thinking concretely . All this concrete thinking culminates in kids’ joys alive.   KEYWORDS Thinking , Concrete , Body , Logic , Living , Kids , Joy Cite this paper Wu, K. (2015) Concrete Thinking.

ABSTRACT This paper compared the rheological properties and compressive strengths of self-compacting concrete (SCC) and conventional cement concrete. The flowability and segregation resistance of freshly mixed concrete specimens were examined by the V-funnel apparatus, while the characteristics of passing ability were investigated with the L-box apparatus. Cylindrical concrete specimens of 100 mm diameter × 200 mm length were investigated for compressive strength. The rheological properties of SCC are incomparable with those of the conventional concrete due to their diverse testing methods and characteristics of ...

ABSTRACT This paper used the existing formulae in estimating resistance parameter of reinforced concrete structure to assess the effect of concrete produced from pit-sand in Akure metropolis, on the resistance parameters of a collapsed building in Oba-Ile, Akure. Site inspections were carried out on the collapsed building, and concrete samples were taken. Both destructive and non-destructive methods were used to determine the structure’s concrete stren...

ABSTRACT The adoption of performance indicators promotes knowledge of quantitative and qualitative material wastes in businesses and, when inserted in a collaborative process, provides a comparative evaluation of results between companies and, thereafter, an identification of best practices (bench-marking). The purpose of this paper is to present the best practices identified by performance indicators, related to the measurement...

ABSTRACT The present study addresses the global concern of sustainability in building and construction engineering and how to an extent the use of demolished aggregate wastes in concrete production contributes towards ameliorating or minimizing the problem. The influence of demolished aggregate waste on the mechanical strengt...
