Get PriceThe cement or mortar is mixed by first adding a portion of the water The sand and cement are then poured into the water and the mixture is stirred for several minutes More water cement or sand can be added if the mixture is too wet or dry Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer
Get PriceBy adding water to the mix it creates a chemical reaction to the quicklime within the cement This means that it sticks to the aggregate and the sand thereby sticking them to one another In addition adding the water to the mixture makes it pourable so that you can add it to a mold or use it to create a slab
Get PriceThis Portland mix is the cheapest of the concrete mixes Demold time is 24 hours but it will take another 2 days for the cement to reach its final color This will dry to a light medium grey The directions call for at least a 3 1 ratio of sand to cement but this is unnecessary for most cement concrete crafts
