· 5 Compressive Strength of Stabilised Compressed Earth Block Masonry. Masonry consists of two materials: the masonry unit and the mortar. Interfacial bond between the masonry unit and the mortar is essential for the masonry to behave as one structural entity. Figure 7.21 shows a masonry prism and a masonry wallette.

· Mechanical properties such as compressive strength, flexural strength, and shear strength can therefore be enhanced if an optimal fiber-reinforcing ratio is identified and used [42,56]. The paper evaluated equivalent flexural strength ( f e ) at different fiber dosages and proposed the model to establish the correlation between

The results of Table 10 show that, for brick 1, the compressive strengths ranged from 5.7 to 7.5 MPa (rejecting the test where bricks were laid horizontally). For brick 2, which had the same dimensions as brick 1 but much lower resistance, the difference between the various results ranged from 1.5 to 2.4 MPa.
