Chemical Attack Resistance Characteristics of Polymer Impregnated Concrete

Rheological Behaviors of Polymer Impregnated Maple Veneer

The objective of this study was to determine rheological behaviors of maple veneer plastic composite (MVPC) prepared by full cell preparation technology through the use of a rotational rheometer. The results showed that at 25 to 105 °C, the storage modulus G' and loss modulus G'' of the MVPC were apparently higher than that of the control. In the range 105 to 210 °C, the storage modulus G' of t...

TAPPIR® - Tunable Aqueous Polymer Phase Impregnated Resins

However ATPE has no large-scale industrial applications yet. This is based substantially on very long phase separation times resulting from low interfacial tensions and low density differences between the phases producing intensive and stable emulsions. This causes an increased footprint of the required mixer/settler devices or the application of additional equipment such as energy consuming ce...

Implications of WTC Attack on Concrete Research

The terrorist attacks on the World Trade Center and the Pentagon have changed the world as we knew it. Although there is clearly an immediate need for reconstruction of Lower Manhattan, it is too early to predict what all of the implications on the construction industry nationwide will be. Yet, the very real terrorist threats we have to learn to live with will have repercussions on the types of...

Chloride Resistance of Concrete

Chemical concrete machine

The chemical concrete machine is a graph rewriting system which uses only local moves (rewrites), seen as chemical reactions involving molecules which are graphs made up by 4 trivalent nodes. It is Turing complete, therefore it might be used as a model of computation in algorithmic chemistry.
