If you are going to use just a small amount of what has been mixed and want to store the rest,

remember that if you used grey cement, then you will have to store it in a dry area or container,

because most grey cement are not oven dried, and will harden with the moisture in the air. If you

used white cement you will find that the mixture does not harden or cake up, as it is called,

because white imported cement has been oven dried, in order that as it travels over seas, will not

harden.
