For its high natural water content (approaching or exceeding liquid limit), large void ratio (normally more than 1), high compression, structural tendency and being easy disturbed, low permeability and shear strength, and small deformation modulus, it’s necessary to control it for overcoming its bad engineering character and meeting some needs.
Based on the existing engineering experiences and theory research theory, Rao Weiguo[2] defined pile-net composite foundation, revealed its property and application vista, and analyzed its formation and work mechanism.

However, the reuse of RCA to manufacture structural concrete is necessary to decrease the environmental impact of buildings and civil engineering works as well as to minimize the consumption of natural resources.
For this aim, the main objectives of this work are to compare experimentally and analytically reinforcing and repairing concrete with 3 different FRP composites in order to develop its application in the civil engineering field. 2 MATERIALS: FORMULATION, ELABORATION AND CHARACTÉRISATION 2.1 Concrete The raw materials used to formulate concrete were: Cement type CEM II/A-L 42.5N, Betocarb HP-OG Limestone fillers manufactured by OMYA SAS, MC PowerFlow 3140 superplasticizer and aggregates: natural river sand called NS 0/4, two crushed natural gravels NG1 4/10 and NG2 6.3/20 and recycled aggregates provided from construction demolition wastes designed by RS0/4, RG1 4/10 and RG2 6.3/20.
