this paper is based on an experimental research that examined the effects of concrete`s major parameters on durability of concrete pavements and curbs under freezing and thawing cycles. these parameters include concrete mix design parameters such as water-cement ratio, fine aggregate percentage and using air entraining admixture and simulating real freeze-thaw cycles that infrastructures underg...

Concrete is a material that often used in the construction industry due to its strong compressive strength and durability. Currently, lot of research being done find new ways increase performance. One these ideas what led creation self-compacting. accepted as most cutting-edge development concrete building industry. Self-Compacting becoming more popular for usage overloaded reinforced construct...

In late 2012 and early 2013 the discrete logarithm problem (DLP) in finite fields of small characteristic underwent a dramatic series of breakthroughs, culminating in a heuristic quasipolynomial time algorithm, due to Barbulescu, Gaudry, Joux and Thomé. Using these developments, Adj, Menezes, Oliveira and Rodŕıguez-Henŕıquez analysed the concrete security of the DLP, as it arises from pairings ...

A short review for design consideration of two common materials used in facade and curtain walling is presented. The characteristics of light-weight facade enveloping a building are different from the conventional steel or concrete structures. Glass cannot crack like concrete and it is much more brittle than steel. Aluminum involves many buckling modes similar to but more common than steel. Owi...

The objective of this research is to investigate the advantages of using large-diameter 0.7 inch prestressing strands in pretention applications. The advantages of large-diameter strands are mainly beneficial in the heavy construction applications. Bridges and tunnels are subjected to a higher daily traffic with an exponential increase in trucks ultimate weight, which raise the demand for highe...
