Chapter 9 STRUCTURAL CONCEPT FOR LIGHT GAUGE

STEEL FRAME SYSTEM 9.1 BACKGROUND Steel is widely used in the construction of multi-storey buildings. However, steel construction is seldom used and is traditionally considered uneconomical for landed properties. In many parts of the world, timber or structural brickwork is preferred whereas

Drywall Expansion Joints:Use drywall control joints or

Drywall control joints or gypsum board expansion joints are used to control cracking in gypsum board ceilings & walls. This article discusses expansion & contraction of drywall / gypsum board and the drywall control joint or expansion joint products used to prevent these problems in building interiors. We cite drywall expansion joint installation specifications, applicable construction Fire Protection American Institute of Steel ConstructionGypsum. Gypsum is commonly used for fire protection, and it comes in a variety of formats. Adding lightweight mineral aggregates such as vermiculite and perlite can significantly increase the effectiveness of gypsum-based fire protection systems. Gypsum plaster can be applied over metal or gypsum lath.

Through Penetrations Gypsum Mineral Uses and PropertiesGypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Planar or flat protection to floors, walls, and ceilings by single or multi-layer gypsum boards or similar fire pro- tecting boards. 2. Board protection to columns and beams in the form of

Mohs Hardness Test

Instead, common objects are used as tools to perform the hardness test:fingernail (hardness = 2.5) copper penny (hardness = 3) glass plate or steel knife (hardness = 5.5) steel file (hardness = 6.5) Using the above testing tools, you should be able to determine the Mohs Hardness of an unknown mineral to the nearest half number on the scale. Other Uses of Gypsum Gypsum AssociationGypsum (calcium sulfate) is recognized as acceptable for human consumption by the U.S. Food and Drug Administration for use as a dietary source of calcium, to condition water used in brewing beer, to control the tartness and clarity of wine, and as an ingredient in canned vegetables, flour, white bread, ice cream, blue cheese, and other foods.

  • What Are R-Values?R-Value UnitsWhat Are U-Factors?Building Material R-ValuesDoors and AssembliesInsulation ManufacturersIn construction, the R-value is the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation.R-values are additive. For instance if you have a material with an R-value of 12 attached to another material with an R-value of 3, then both materials combined have an R-value of 15.WALL & FLOOR ASSEMBLY GUIDESteel Studs Gypsum Board Single Layer of can be used between the gypsum wall board and the stud to break the vibration path. the bottom and top plates.

Case 2:Placing the plate beneath adhered gypsum cover board provides little improvement due to poor thermal resistance of the gypsum, raising the R-value from R-19.2 to R-19.5.
