Compressive strength of sandstones is affected by weathering conditions. Samples of ancient Nubian sandstones are coated with Paraloid 44 (B44), Paraloid 72 (B72), Ethyle silicate and Wacker (OH100). The results showed that in general, Mechanical Compressive strength of sandstone decreases due to salty groundwater action.
· So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test

· The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and
· The strength of intact rock is, together with the rock mass structure, probably the most important properties for rock engineering. To accurately estimate the Mohr–Coulomb (MC) strength parameters—cohesion c and angle of friction ϕ—of a rock, triaxial tests must be carried out at different stress levels so that a failure envelope can be obtained to be linearized.

Strength . Ordinarily, the strength of a stone is not of primary importance, as very often the loads to which it is subjected in a structure are much below its permissible crushing strength. Durability . Stones should possess a natural durability to withstand the destructive effects of various agents continuously operating on them.

In sandstone, however, the Wedge-Bolts exhibited greater ultimate strength with lower variability between tests. Regardless of the observed failure mode, these results suggest that the published design values for installation in 4,000 psi concrete are appropriate, and in some cases conservative, for all variable combinations tested.

The streak of Sandstone is white whereas its fracture is conchoidal. Luster of Sandstone is the interaction of light with the surface of Sandstone. Luster of Sandstone is dull. Sandstone cleavage is perfect.
· This compaction strength, Cc, is itself a function of porosity as well as mineralogy, diagenesis, and texture. In Figs. 4a and 4b, the behavior of two rocks under hydrostatic pressure is shown. The high-porosity (33%) sandstone ( Fig. 4a) has a low "crush" strength of about 55 MPa.
