These features made the composite materials particularly appealing for both high performance and sustainability during the in-service life [2].
The mechanical behavior of these multi-phase materials is based on the capability of precisely orienting the continuous reinforcing filaments [3].
The numerical approaches, previously implemented and validated on conventional materials, are applied in this study considering an innovative vitrimeric matrix.

Experimental details 2.1 Materials In the study, Ordinary Portland cement (P.O 42.5), fly ash (FA, Class II) and Ground blast furnace slag (S95) were used as binder in the mix proportions.
For high strength concrete (A3) with low water-binder ratio, less porosity and more cementing materials, concrete was denser and contained more Ca(OH)2 per unit volume.

The goal of this paper is to predict the sound reduction index of a double-leaf panel varied with thickness of wooden studs and materials by the statistical energy analysis (SEA).
(13) Therefore, the formula of the sound insulation of the double wall is Comparison between the predicted and measured data Three configurations of double-leaf lightweight panels with different building material are listed in Tab.1.The size of these walls are set to l=4m, w=3m Tab.1 Properties of the double walls Double wall The member of the wall Dimensions m Density kg/m3 Young's modulus N/m2×109 Double wall 1 (50mm) Plasterboard(side 1) 4×3×0.0125 710 2.52 Plasterboard(side 2) 4×3×0.0125 806 2.12 Frame 3×0.050×0.050 380 7.64 Double wall 2 (100mm) Plasterboard(side 1) 4×3×0.0125 710 2.52 Plasterboard(side 2) 4×3×0.0125 806 2.12 Frame 3×0.050×0.100 475 8.24 Double wall 3 (150mm) Chipboard(side 1) 4×3×0.018 678 1.49 Plasterboard(side 2) 4×3×0.0125 801 2.22 Frame 3×0.050×0.150 469 6.94 The sound insulation of these double walls

The vital role of the construction industry is cooperation through relations from various other sectors, such as the material processing industry, energy, finance, transportation, and mining.
· Based on the time factor, the rank order of the disputes is climate change, work that is not according to the specified schedule, and delay in providing materials and tools
· Based on the cost factor, the ranking of disputes is obtained by increasing the price of materials and wages, disputes and delays related to payment, and contractor errors in submitting prices during tenders.
Based on the cost figure, disputes are ranked by expanding the cost of materials and compensation, debate and delays related to instalment, and temporary worker mistakes in submitting expenses amid tenders
The most influential cost factor is the increase in material prices and wages.
