PERLITE

PERLITE. P. erlite was formed millions of years ago when the Rocky Mountains erupted from the Gre a t We s t e r n Pl a i n s . As volcanoes spewed molten la- va over the countryside, the lava cooled to for m deposits of glass-like minerals such as obsidian, pitch- stone and pumice. One type of lava was named perlite by geologists because under ...

Vermiculite Concrete

Vermiculite Concrete Introduction Vermiculite concrete is a low density non-structural construction product. It is insulating (both thermally and acoustically) and intrinsically fire resistant. It is normally made simply by mixing exfoliated vermiculite as the aggregate, with cement and water, plus additives such as plasticisers if required.

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.

Development and Performance of High Strength Lightweight Concrete …

With the help of the trend lines shown in Fig. 2, the on average 1.95-fold higher compressive strength of the perlite lightweight concretes becomes apparent. Especially in density ranges from 1100 kg/m 3 to 1200 kg/m 3 the mixtures M1 to M7 seem to outperform the aerogel concretes used for comparison.

SCHUNDLER COMPANY-Transit Mix Perlite Concrete

The mixing procedure used by many transit operations is as follows: Determine the load of the mixer. Add to the mixer the correct amount of water for the load. Add the correct amount of air entraining agent and cement to the mixer and mix until a slurry is formed. Add the required number of bags of perlite concrete aggregate.

Perlite Lightweight Insulating Concrete Roo˜ng

Use an ordinary rotary concrete mixer with a large mixer capacity and fast mixing (rpms). 2 • 1/6 Mix Design is the most often used ratio for roo˜ng applications as it provides an optimum balance between strength, insulation and lightweight.

Perlite Cement-based Lightweight Insulating Plasters

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.

PERLITE INSULATING CONCRETE

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 INSULATING CONCRETE

It is recommended the board be covered by perlite concrete to finished thickness before the slurry is set. 6.2 – Curing Normal Conditions: Perlite concrete has an adequate mixing water content so as to have sufficient water for proper curing of the concrete without additional precautions. Under these
