Rapid Set cement in not a gypsum cement. Unlike gypsum, Rapid Set® cement can be used in wet environments.

Answer: Gypsum is added to control the "Setting of cement". If not added, the cement will set immediately after mixing of water leaving no time for placing.

A white mineral that is milled, heated, hydrated and formed into drywall; or used to manufacture plaster.

Cement, or Portland cement, is a dry powder made from limestone and other materials. It is burned in a kiln and then ground finely. Cement reacts chemically with water to cause concrete to harden. There are several different types of Portland cement, designated as Type I, Type II, Type III, etc.

Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, marl, shale, iron ore, clay, and fly ash. The kiln resembles a large horizontal pipe with a diameter of 10 to 15 feet (3 to 4.1 meters) and a length of 300 feet (90 meters) or more. One end is raised slightly.

No. Our cement has been made easy to mix in the provided packaging without the need and extra cost of a separate mixer.

Yes, the Moon Bounce will be secured with sand bags rather than stakes. However it is HIGHLY recommended that the Moon Bounce be set up on grass whenever possible. It is possible that someone could slip getting into our out of the moon bounce and hit the ground. The cement is unforgiving when this happens. There is an additional fee for hard surface setups.

The Parallax Ez-Flow CDS is designed for the percutaneous injection of bone cement but have been optimized to work with the Parallax line of cement products. The Parallax IDS is designed for use with a proprietary cartridge cement-it will not work with vials or other types of formats.

A predetermined amount of gypsum is added to the strike water before the mash is mixed. Generally, 1 to 3 teaspoons will be plenty to harden the water and lower the pH slightly with strike water of 30 to 120 PPM total hardness. We generally recommend single temperature (infusion) mashing for the beginner, as all William's grain malts are modified enough to convert fully at a single temperature rest of 150? - 158? F. held for one hour.

Type X gypsum wallboard is specially formulated to provide superior fire resistance over regular gypsum wallboard. As a result, it is typically heavier than regular drywall.

In most instances the gypsum casts should be pre drilled and sheet rock screws should be used to fasten the to the framing. We are available to answer any questions you may have on installing our products.

Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver.

No, Parallax cement delivery systems cannot be reused or resterilized and are to be disposed of after use.

If the cement sets too quickly that typically means it was mixed/injected at too high a temperature or too high a humidity. The cement is intended for use at 23 C (73 F)-cooler temperatures will lengthen the setting time while higher temperatures will quicken the set time.

This is a concrete question more than a radiant heating question. All concrete applications must be structurally satisfactory. There is no important difference between concrete mixes from the heating standpoint.

The amount of cement added varies typically from a range of 5% to 30%. There is no "cookbook" recipe. Quantity of cement to be added is determined through a treatability study and mix design conducted on the individual subject waste or medium. Treatability studies can be simple or more involved depending on the project requirements. A description of an involved treatability study written by the U.S. Army Corps of Engineers is found at: http://www.usace.army.

Cement coating is a colored concrete resurfacing material made of Portland Cement, Silica sand with some acrylic bonding agents.
