Formula for refractory cement Details Hackaday.io

This is a formula for making excellent refractory material to use to line the walls of a melting furnace. I am routinely melting aluminum and brass and I have been looking for a formula that is strong and lasts a long time. All of the formulas that I have seen that use Portland cement need replacing pretty often because Portland does not hold up under heat.

Construction Perlite

Insulating values of a Perlite concrete roof deck depends on the density of the concrete mix that is prepared. Typical U values range from (1.19 W/m².k) for a (50 mm)(350kg/m³) to (0.6 W/ m².k) for a (100 mm) thick roof deck.

How Much Perlite Do I Need For A Pizza Oven Ceramics

Make a mix of vermiculite and cement that is 4 1 ratio and add enough water to allow the mixture to form solid shapes. Too much water will mean longer curing and drying later on. Use gloves to apply the concrete to the ball building up a solid layer. Can I use normal cement in a pizza oven

How to Mix Perlite and Cement Hunker

Perlite concrete mixed at a ratio of 1 part cement to 6 parts perlite has an insulation value or "k" value of 0.64 and a compressive strength of 125 to 200 pounds per square inch. At a ratio of 1 part cement to 4 parts perlite you achieve a "k" value

Cement and perlite vs. cement and sand

Cement and perlite vs. cement and sand. Fleur. 13 years ago. I ve been toying with the idea of using perlite instead of sand with cement. Ie. 1 part cement and 2 to 3 parts perlite to make a lighter mix and curing it as one does with the cement/sand mix. My objection to
