CONCLUSIONS

1.                        The average ma:<imum compressive load capacity for the (6) samples tested is
                          259.5 ld{ with a standard deviation of 1.87 kI'[, ie. 259.5 + 1.87 k]I

I                         The average ma:<imum compressive strength for the (6) samples tested is
                          2.89 MPawith a standard deviation of 0.023 MPq ie 2.89 t0.023 MPa.
