PERFOMANCE EVALUATION ON LIGHT TRANSMITTING CONCRETE (TRANSLUCENT CONCRETE)

Computational Modeling of Translucent Concrete Panels

The last decade has witnessed a heightened interest in making buildings more sustainable, which has been fueled largely by the increase in energy costs and advancements in manufacturing technology. Lighting consumes a substantial amount of this energy, making it necessary to look for alternative technology that depends more on natural lighting. This study investigated a novel building envelope ...

Effect of the Concrete Strength on the Concrete-Steel Bond in Concrete Filled Steel Tubes

In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

Research on Concrete Aggregates

Portland cement concrete has been used extensively for many years as a construction material in bridges, buildings, highway pavements and other structures. Numerous structures and pavements that have been in service for decades illustrate the good durability and value of con­ crete when properly used in engineering construction. For example, the first concrete pavement built in the United State...

Reflections on Concrete Incompleteness

How do we prove true, but unprovable propositions? Gödel produced a statement whose undecidability derives from its “ad hoc” construction. Concrete or mathematical incompleteness results, instead, are interesting unprovable statements of Formal Arithmetic. We point out where exactly lays the unprovability along the ordinary mathematical proofs of two (very) interesting formally unprovable propo...
