Introduction The fiber-reinforced composite materials using on the reinforcement of concrete structures are now mainly carbon fiber and Kevlar.
The basalt fiber is the preferred alternative to carbon fibers and aramid fiber reinforcement materials.
Other mechanical properties of materials are stated in Table 1 and Table 2.
Basalt fiber materials application prospects [J].

In plate-cone reticulated shell of composite material, the stress of cone unit is far less than intensity limit of materials, due to the low modulus of elasticity the composite (GFRP) and thinner thickness of laminated plate, local buckling is the main controlling factor for design.
Composite modeling is difficult to mould design, laminated floor layer in ANASY software, the material is to determine the coordinate direction of material attribute, by unit is the only sure, coordinate, coordinate to ensure materials determine the coordinates of the composite Shell element, the unit is default coordinate basis I - j edge coordinate system.
Considering the production cost of materials and the man-hours, overmuch layer number is unfavorable, total layer number of 4 layers is the best in the premise of reasonable laying way.

The present study is focused also in the mechanism of chloride penetration in cementitious materials.
Chloride ions penetration in cementitious materials is one of the processes widely responsible for the degradation of concrete structures.
Materials The materials used in this investigation were Portland cement, GGBS, aggregate, water and super plasticizer.
Portland cement (CPA-CEM-I / A 42.5) conforming to the Algerian standard NA 443 and GGBS were utilized as cementitious materials.

Operating cost function of logistics transportation network The function and composition of logistics transportation network While providing transportation service to its clients, in order to minimize the logistics cost, the enterprise will firstly package, process and distribute goods and materials for different customers in the logistics center, and then organize the transportation; finally based on the clients’ need finish the evacuation and allocation in distribution centre or logistics centre near the clients.
(1) the cost of the sub-system ,“collection” For appropriate transportation of the goods, we set the sub-system, “collection” .Its fuction is to collect the materials.
