![]() Landfill for DRY waste-cured cement creates no environmental damage. The cement industry is the second largest CO2 emitting industry behind the energy industry. The result is ground and combined with gypsum and small amounts of other materials. Limestone is heated to 1450 degrees celsius, releasing CO2. ![]() Can also be used to model full scale details. USESĬan be used as a scaled modeling material-forms can be made of plexi for a shiny finish or wood for more texture. Powder that hardens and binds with the introduction of water key ingredient in concrete. Portland, Masonry, Portland Blastfurnace, Fly Ash DESCRIPTION These joints take a little longer to make right. Miter Joint (pictured right) the object modeled will appear to have more unity and solidity. Use if the design has a particular directionality. Standard Joint (pictured left) the right side here will read more dominantly. Untreated wood will biodegrade without any issue. Usable scraps to Reuse Stations, unusable scraps to wood dumpster behind shop. Tilia Americana (American Basswood) DISPOSAL The tree becomes mature in 10–15 years at which point it is harvested and cut down to desired sizes, then shipped. The American Basswood tree is native to states as far west as Minnesota and as far south as Missouri, stretching all the way to the east coast. Cuts with the grain must be carefully made to ensure the blade does not follow the slight curve of the grain instead of the straight edge cuts against the grain must be scored and made in a number of passes. Basswood accepts all types of glues, especially craft glues, and can be cut by hand at thicknesses up to 1/8”. Sheets, Rods, Dowels, Structural Shapes DESCRIPTIONĮxcellent modeling material. Almost all cuts are best made with multiple, low pressure passes-this reduces the chance of slipping and increases the precision of the cut.īalsa wood grain types Tangent (A), quarter (B), and random (C) grain types SAFETY NOTESĪlways be careful when cutting-use a sharp blade. Untreated wood will completely biodegrade without any issue. Ochroma Lagopus (Balsa Wood Tree) DISPOSAL Balsa wood enjoys a relatively quick regrowth rate of 6–10 years. These trees don’t grow in farms, and tend to be harvested directly from the jungle. Trees harvest for balsa wood can be found in northern South America, and 90% of all balsa wood comes from Ecuador. Because the wood is so light, it also distorts under pressure from anything but the sharpest blade, making clean joins more difficult to make. The very apparent and sloppy looking grain keeps balsa in the realm of mostly massing or sketch models. USESīalsa wood is easier to cut and lighter than basswood, but much more difficult to make into a good looking model. Tan, heavy grained and slightly textured wood.
