I want to make some 10lb weights using some 1.5 L bottles and concrete.
a) will the curing concrete put out enough heat to melt or deform the plastic bottles?
b) will any mass be lost in the curing process?
c) can the concrete cure if the bottle is sealed?
d) how can I ensure that the mix is well mixed? Would it be better to put the concrete mix in first or the water?
e) what are some ways to increase the density of concrete?
