Exploitation of Particle Migration Mechanism to Promote Economy and Ecology in Concrete Technology

Key Engineering Materials, 2006
The computer simulation study of Portland cement blending confirmed the major mechanism to be size segregation in the Interfacial Transition Zones around the aggregate particles. Fine particles tend to move through the skeleton of larger particles towards the surface of the aggregate grains, improving local density.

olymethylsilsesquioxane Oligomers as Ecologically Friendly Binding Agents for Particle Boards

INEOS OPEN
The possibility of using multifunctional methylsilsesquioxane oligomers as ecologically friendly binding agents for wood chipboards is investigated. The physical and mechanical properties of the resulting particle boards are studied and compared with those of the boards containing a formaldehyde resin as a binder.

Sedimentary particle sizes and the ecological grain of food resources for meiobenthic copepods

Estuarine, Coastal and Shelf Science, 1986
Abstract On average, sand particles larger than 300 μm have at least one large smooth facet on their surfaces on which the epifloral food of meiobenthic copepods is distributed as a coarse-grained ecological resource. Sand particles smaller than 300 μm have irregular surfaces composed of pits, faults and encrustations in which food organisms are ...

Ecological composite material with oil shale ash particles. Mechanical properties

Engineering for Rural Development
The need for “ecological” and “green” materials is increasing because of the strong demand to reduce the speed of climate change and decrease carbon footprint of human activities in nature. In the cement production process high amount of CO2 is obtained as by-product.

Design of ecological concrete by particle packing optimization

2011
The goal of this research project on Ecological Concrete was to reduce the CO2-emission of concrete and to reuse secondary materials form concrete production and other industries simultaneously. This also minimizes the use of natural resources and the production costs.
