Expanded perlite is distributed evenly in the concrete mix, which is visible in macroscopic images of lightweight concrete samples containing 30%, 45%, and 60% of expanded perlite by volume after 28 days of curing ( Figure 5 ). The high plastic viscosity of the RPC mix, which prevents the segregation of ingredients, has an impact on the even ...

Instructions. Make the cement mixture in a bin using one gallon peat, one gallon "Portland" cement, and one gallon perlite. Wear a mask to avoid breathing dust and use gloves when mixing, as concrete can burn the hands. Slowly add approximately 2 1/2 quarts of water as if you were making dough, being sure to add the last part of water slowly.
