The same holds true for covering a concrete patio. Stones of a half-inch thick, properly installed with thin-set and or mortar, and made with Sand Mix have a compressive strength of over 5,000 psi. The savings in raw material costs between pouring concrete into a half-inch thick mold, versus a two to three inch thick mold is substantial.

The 28-day compressive strengths of MCVS3 were compared with the 28-day compressive strength of control mortar. The compressive strength ratio of CVS mortars produced in this investigation to compressive strength of control mortar were 44.79% for MCVS1; 75.33% for MCVS2 and 96.83% for MCVS3 mixtures.

Rocks in volcanic lava compositions are highly intense and have strong compressive strength. Components of breccia with smaller crystal- line grains, irregular shape and configured with vary- ing grains, consisting of weaker rocks, compared to the rocks in volcanic lava, were apparently impacted by compaction.

The average uniaxial compressive strength (σci) of lava rocks was moderately strong (σci = 72.4 MPa), with breccia rocks being 62.2% weaker (σci = 27.4 MPa). These values can partially be contributed to lava rock's very low porosity (0.054) and breccia rock's higher porosity (0.19).
