Types of Plaster White Plaster: white marble aggregate (sand) and white cement (ratio of 2/1) and water. Variations in water-to-plaster ratio will affect cast absorption, strength, and performance. Do … Stearic acid (/ˈstɪərɪk/ STEER-ik, /stiˈærɪk/ stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain. Cubic lbs Plaster lbs Water Cubic lbs Plaster lbs If the mix lists the water in gallons, multiply the gallons by 8.33 to find how many pounds there are in the mix. The ratio of cement and sand for plastering is given below. A check on the ratio can be made at any time by weighing the slurry in a container of known volume. PVA glue (white glue) does get used as an additive for plaster of Paris. Immediately pour out half of the plaster onto the pre-dampened spot board (the rest will keep better in the bucket).

If you feel the plaster is a little too thick then you can add a little more water and give a short re-mixing but try and avoid needing to do this if you can. It is a waxy solid and its chemical formula is C17H35CO2H. For a given type of cement, aggregates of same type and size, and same methods of mixing, the concrete develops a maximum compressive strength of 380 Kg/cm 2 at a W/C=0.4. Example: A Rectangle 12x8x4=384 cubic inches. Always round up. Water/Powder Ratio 37 mL/100 g Working Time 7 - 9 minutes Setting Time 14 minutes Setting Expansion 0.20% Compressive Strength, Wet (1hr.)
