Question $1$: $(3$ marks$)$

Given the two sand samples below from the same source, calculate the:

a$)$ Moisture Content

b$)$ Absorption

c$)$ Surface Moisture

d$)$ Moisture state of the sand sample, will it donate or absorb from the

concrete mix?

Sample A:

Mass of Sand ${?}_{(Wet)}=678\mathrm{.}8g$

Mass of $San{d}_{(OD)}=625\mathrm{.}0g$

Sample B:

Mass of Sand ${?}_{(SSD)}=642\mathrm{.}2g$

Mass of Sand ${?}_{(OD)}=637\mathrm{.}7g$
