Cementitious fiber composite

Mai (1985) has also given a review of the fracture mechanisms in cementitious fiber composites. The total fracture toughness, / i, is given by the sum of the work dissipation due to fiber pull-out, fiber and matrix fraetures, fiber-matrix interfacial debonding and stress redistribution, i.e..

Compressive Strength (Fig. 1 and 2). The PVB composite, placed with no fiber, has an average compressive strength of 37.7 MPa with density about 1500 kg/m and water to cementitious ratio of 0.4. Fig. 1 shows a comparison between the PVB composite and 1) a lightweight concrete (L) having a compressive strength of 13.4 MPa with the same density and water to cementitious ratio... 

PVB/PVA fiber cementitious composites have almost twice the fracture toughness of regular fiber cement mortars despite having almost half the density.
