The Measurement of P-, S-, and R-Wave Velocities to Evaluate the Condition of Reinforced and Prestressed Concrete Slabs

Table 4

R-wave velocities (m/s) along 12 paths in slabs S1, S2, and S3.

Slab	Path
	1	2	3	4	5	6	7	8	9	10	11	12	Min	Max	Avg	Std
S1	1768	1855	1913	1753	1951	1835	1988	1894	1882	1921	1917	1882	1753	1988	1880	69
S2	2025	1951	1874	1988	2006	1992	1894	2043	1855	1795	1932	1855	1795	2043	1934	79
S3	1853	1988	1970	1917	1992	1894	1855	1971	1845	1932	2006	1888	1845	2006	1926	75

Avg = average velocity and Std = standard deviation.
