1) Add all materials except perlite to mixer; then mix until this slurry is fairly uniform. Two minutes will. usually suffice. 2) Add all perlite; then mix again only long enough for a uniform mix, probably another two to three minutes. Excess water and under mixing may reduce yield and workability.
Perlite Concrete Offers Many Advantages Beyond Its Light Weight.

Perlite lightweight concrete is used in many different applications. These include lightweight tile mortar, statuary, decorative stone ...
For most uses to maintain a proper balance between insulation value and compressive strength, a 1:6 (one part Portland cement by volume to 6 parts perlite by volume) mix is chosen with a density between 384 and 480 …
Add all materials except perlite to mixer; then mix until this slurry is fairly uniform. About 2 minutes. Excess water and under mixing may reduce yield and workability. Over mixing may degrade the perlite and increase concrete density, reducing yield. Optimum mixing cycle can usually be determined with one or two trial batches.
Mix Design Data. The proper proportions of materials for various perlite concrete mixes are shown in the following table. The importance of properly designing and specifiying the mix and the proper use of the air entraining agent cannot be overemphasized. Materials per Cubic Yard Based on Yield. Mix Ratio.
A 5:1 vermiculite or perlite, cement ratio (by volume) is approximately double the strength but half the insulating capacity of a 10:1 ratio. ... If you are adding your 50/50 mix in an effort to gain strength then a foil layer between it and the oven will not allow it to bond. In addition a foil layer acts as a vapour barrier unless it's ...
Perlite insulating concrete consists of an appropriate mixture of portland cement, perlite aggregate and water. Its weight can be varied in the range of 20 to 50 pounds per cubic …
p o r tions of perlite and cement which are to be mixed, the architect can strike a desirable balance between the s t r ength and insulating value of the concre t e . A mix of one cubic foot of cement to six cubic feet of perlite ag-g r egate provides both excellent strength and insulation va l u e . Perlite insulating concrete mixed in these pro-
Perlite insulating concrete consists of a mixture of expanded perlite, Portland cement, water and an air entraining agent. The dry concrete weighs from 20 to 50 pounds per cubic foot, depending on the mix design selected. It is mixed in place, using the same equipment required for handling ordinary concrete, including transit mix trucks.
VERMICULITE or PERLITE and PORTLAND CEMENT – Dry Mix 5 parts Vermiculite or Perlite - to - 1 part Portland Cement in a Mixing Tub or Wheelbarrow - (5 Gallons / Shovel - to - 1 Gallon / Shovel). Add just enough water to get the entire blend wet as you mix with a shovel or hoe (hoes are good for this process). DO NOT OVER WATER!
P. erlite insulating concrete consists of an appropriate m i x t u r e of portland cement, perlite aggregate and w a t e r . Its weight can be va r ied in the range of 20 to 50 pounds per cubic foot, depending on the mix design se- lected. This is in comparison to sand and gra v el con- c r ete which weighs 140 to 150 pounds per cubic foot and ...
Perlite is a common term used for a glassy natural volcanic rock used in construction in various mixtures for its fire resistance, low density, and thermal and acoustic improvement properties ...
Add all materials except perlite to mixer; then mix until this slurry is fairly uniform. Two minutes will usually su ce. Add all perlite; then mix again only long enough for a uniform …
By integrating perlite into the mix, the weight of concrete can be reduced by nearly 20%. The resulting lightweight concrete maintains robust strength but is easier to handle, faster to set, and, crucially, puts less stress on the structures it's used in. This lightweight solution is perfect for floor fills, roof decks, and other structural ...

Physical properties of perlite concrete vary according to mix designs. Perlite concrete can be made with a dry density of 20 lb/ft 3 (320 kg/m 3) or with the addition of sand or other aggregates up to 90 lb/ft 3 (1440 kg/m 3). The lower the density, the higher the insulating value.
General Mixing & Installation Instructions. Place 80% of the required water in the mixer, followed by lime (if used) and cement. Add the remaining water and mix until the slurry is uniform, approximately 1 to 11⁄2 minutes. Add the perlite, and any additional aggregate, and sprinkle in the chopped bers while the mixer is rotating.
