The directions call for at least a 3:1 ratio of sand to cement, but this seems unnecessary when making cement & concrete crafts. When I used a 3:1 ratio, I ended up with a great deal of pitting. I made a bowl using a 1:1 ratio and at that ratio, I found this to be as smooth and moldable as Cement All to work with, as well as has the same finish ...
The type of sand greatly affects the color of white concrete and offers additional opportunity to vary the color effect. Fine sand particles act as a pigment to color the cement paste. In many cases, the fines prepared from crushed coarse aggregate are used instead of pigments.
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. Concrete - 1 part cement, 2 parts concreting sand and 3 parts 20 millimeter aggregate. Mortar - 1 part cement, 4 to 5 parts building sand.
Measure out one part white cement, six parts white sand and one part lime. For consistent measuring, use containers of the same size to scoop and level each part. Add the sand and cement to a wheelbarrow. Add the lime in a separate container that holds at least four times the volume of the lime. Measure and add 2-1/2 times the hydrated lime's ...
Using mortar in place of concrete isn't a good idea as the two have dissimilar compressive strengths. If you are only able to use the white mortar you may be able to make it concrete-like by adding a shovel full of Portland cement and than mix (1) shovel of gravel with (2) shovels of plaster sand …

Typically used as the compound for joining masonry, stone or ceramic units together, mortar is made by combining cement, lime and sand. Mortar typically has a higher water to cement ratio when compared with concrete which allows greater workability and is required to form mortars bonding properties. Typical mortar types are discussed below and ...
As with standard Portland cement concrete, it is best to build forms to contain the soil-cement surface. If building permanent forms, use pressure-treated dimension lumber (2 x 4s are generally best) nailed together and staked in place. Use a level to make sure the forms have a slight pitch to allow for water to drain off. A pitch of 1/4 inch ...
