Cars with materials start out from the warehouse and go along the road E to distribute the materials.
After all materials are distributed they return to the warehouse.
The capacity for distributing cars is Q, time windows for each station to accept materials is Ti(i∈N).

Therefore, these materials are key alternatives to traditional construction materials for the energy-efficiency renovation of existing buildings.
Up to now, biobased construction materials are mostly used for their insulating properties than for structural purposes.
The final objective of this project is to define an indicator to predict the compatibility between a mineral binder and vegetal particles in order to generalize the production of plant-based concrete based on local resources. 2 MATERIALS AND TECHNIQUES 2.1 Materials The mineral binder is a Portland cement CEM I.

The materials were SiO2, B2O3 and soluble glass as binder.
The sample was the graphite anode used in molten salt electrolysis of calcium; the raw materials were boric acid, SiO2 which can be replaced by common glass and soluble glass as binder.
Table 1 Results at different condition of the ratio of raw materials according to the first method (sintering time was 1h) No.
And because coating materials can permeate to fill graphitic pores, the diffusion of oxidative gas is prevented.

Laser cutting is a thermal process which is used contactless to separate materials.
During laser beam machining, the resultant thermal effect depends on the concentration of the beam and the physical properties of materials.

LCA is not only applied to technological sciences and natural science, but also is applied extensively to social science, economic science, management science and international relationship etc.
For instance, a series of equipment activity, such as manufacturing of the tank, overhauling repairmen of naval vessel, maintenance of fighter plane, accession of fuel of rocket guided missile, warehousing and transportation of Military Materials etc, may all cause polluting to the surrounding environment seriously.
Resource Index material kind, material utilization and recycle ratios, material quantity, the proportions of poisonous material, material consumption, part can dismantling and recycle rate, etc.

The grinding force ratio, tn FF /=λ , is an important parameter used to evaluate the grindability of materials.
So the grindability of materials can be improved during NUAG process.
