3、to properly evaluate, select, and specify. Every natural stoneproduct is unique, having its own physical properties and performance capabilities. Responsible stoneselection involves extensive and objective evaluation of both the stone material and the application inwhich it is required to perform.Th

4、is guide presents a cursory review of the different stone types commonly used in construction,common applications, available finishes, and factors affecting product costs. It is intended to be usedin combination with good judgment, responsible engineering analysis, local building codes, and anyother

5、 available resources. It is not a “how-to” or a “step-by-step” guide, and has been prepared withthe assumption that the user has some familiarity in the use of natural stone prior to utilizing thisguide.Past performance is the best test of a dimension stones durability. Yet because the physicalprope

6、rties of a natural stone can vary within a single deposit, even stones with a history of satisfactoryperformance may need to be tested to ascertain the quality of the current production stock. Commonphysical property tests include absorption, density, compressive strength, modulus of rupture, flexur

7、alstrength, abrasion resistance, and anchor strength. Additional tests may also be required depending onthe material and application.In a high proportion of the cases, failure of a natural stone in service is a result of improperapplication, rather than the inherent properties of the stone. Placing

8、stones in unsuitable environments,faulty fabrication, installation, or construction practices, and incompatible associated materials arefrequent causes of stone system failures (for example, high-porosity stones in subgrade applications,inadequate anchorage or expansion space, mortars leaching alkal

9、is, inappropriate strength mortars,staining grouts, voids in setting beds, and pavement stones with inadequate resistance to abrasion).In selection of natural dimension stone products, the application as well as the aesthetic appeal mustbe considered. While aesthetics are important to the design, th

10、e selection of the proper stone material,thickness, anchorage, and related components is necessary to ensure meeting the performance anddurability requirements of the design.1. Scope1.1 This guide is intended to be used by architects, engineers, specifiers, contractors, and material suppliers who de

Introduction5.1 Natural stones have long been used and admired for their beauty and permanence. As a natural material, each piece of stonehas features and physi

24、cal characteristics that make it unique. The rich variation in color and texture, as well as its ability to agegracefully in the exterior environment, hashave made stone one of the most popular materials for construction, sculpture, andmonuments.5.2 Varieties of stone possess certain properties maki

25、ng it suitable for a specific application. Stone geology (mineral content andstructure), compressive strength, flexural strength, resistance to absorption and erosion, as well as its ability to be worked, varywidely by stone type. These are all key characteristics that dictate the best use of the ma

26、terial and must be considered during theprocess of stone selection.6. Applications6.1Several major categories of stone applications are introduced briefly as follows: Exterior Applications6.1 There are several major categories of exterior applications for stone; each of these is introduced below.7.

27、Load-Bearing Masonry7.1 Load-bearing masonry is perhaps the oldest form of stone construction. Its defining feature is the transferring of structuralload vertically by relying on the compressive strength of the stone to support itself and other imposed loads. Due to the weightof the stone itself, st

28、ructures built in this manner tend to be of limited height. As the height of the structure increases, the wallthickness at the structures base must increase, thus requiring large individual stones, or multiple wythes of stone. The costs of suchwalls are typically higher than other systems, due to th

29、e large amount of stone and labor involved.8. Cladding8.1 In response to the limitations and expense of load-bearing masonry, stone cladding systems were developed. CladdingC1528 12a2systems can offer the appearance of load-bearing masonry but without the mass and expense. Cladding systems also offe

30、r a widevariety of applications, allowing greater architectural innovation.8.2 When stone is used as cladding, it is exposed to unique loading characteristics that can require complex structural analysisand detailing in order to be used successfully. Materials other than stone are also often integra

31、ted into cladding systems, requiringconsideration of their material properties as well as compatibility with the stone components.9. Building Trim9.1 Stone has been and continues to be used in architecture to accent other building materials, or to perform a specific purpose.Stone is often integrated

32、 into wall systems as decorative belt courses, window sills, lintels, arches, or water tables. Stone can addan element of interest to buildings, in addition to performing as a durable wall component with a specific and well-defined purpose.10. Pavements10.1 From cobblestone streets to modern plazas,

33、 stone is used to carry vehicle and pedestrian traffic. Modern systems includethose bearing on pedestals and traditional sand or cement-based setting bed systems.10.2 Materials used for steps must have a high resistance to abrasion and provide a surface with adequate slip resistance forpublic safety

34、. Many varieties of dimension stones, with appropriate finish, will satisfy both of these requirements.11. Steps11.1 Materials used for steps must have a high resistance to abrasion and provide a surface with adequate slip resistance forpublic safety. Many varieties of dimension stones, with appropr

35、iate finish, will satisfy both of these requirements.11.2 Steps are manufactured from dimension stones as “cubic,” in which the tread and riser faces are of one piece of stone, andalso “veneered” in which multiple pieces of thin stone material are placed over a concrete or steel frame to form the tr

36、ead and risersurfaces.12. Coping12.1 Wall systems that are fully exposed to the environment, such as roof parapet walls, balcony and terrace enclosure walls,and planter walls, are particularly susceptible to water penetration. Stone coping and wall caps are often used to help protect theunderlying w

37、all system from excessive moisture penetration and associated distress.12.2 Copings and wall caps can also add a visual accent to the wall system, improving the appearance of the wall system bydefining changes in the wall configuration.12.3 Stone copings and wall caps are typically jointed, therefor

38、e, protection of the wall system is also reliant on proper treatmentof the joints.13. Roofing13.1 Roofing applications for natural stone are typically limited to slate, a variety of stone that can be quarried and fabricatedinto thin, shingle-shaped elements. Dense, nonporous stones can provide a dur

39、able, water-resistant roof system that effectivelyutilizes the unique physical characteristics of the material.14. Ornamental, Sculpture, and Monumental Elements14.1 Many varieties of stone possess characteristics that make them a desirable material for sculpting and carving. Most stonevarieties can

40、 be worked by hand or power tools into unique shapes and representations, including engravings and reliefs. Properlyselected stones can demonstrate resistance to environmental effects, thereby providing a sense of permanence to monuments anddecorative sculpted items.COMMON DIMENSION STONE TYPESINTER

41、IOR APPLICATIONS OF DIMENSION STONE15. Interior Applications15.1 Stone is often used at the interior of buildings due to its exceptional durability, beauty, and classical appearance. Due tothe lack of environmental exposure, these applications are usually more forgiving of the material and allow for

42、 a broader rangeof stone varieties to be used. The major categories of interior use are discussed briefly below.16. Flooring16.1 Stone floors are typically highly durable, low maintenance, and aesthetically pleasing. When using stone as flooring, onemust make sure that the finish is appropriate for

43、its intended use; stone used for flooring should be abrasion resistant and have afinish that is not slippery to foot traffic when wet.16.2 Joint conditions in floor installations are also critical; while interior flooring is not subject to the same temperaturefluctuations as exterior installations,

44、the joint system should include expansion joints that will accommodate cyclic variations inthe stone dimensions over time, particularly if there is a substantial heat load from sunlight exposure or below floor-heatingelements.C1528 12a316.3 Stone flooring and the joint materials should also be relat

45、ively impervious to moisture; it is not unusual for interior floorsto be cleaned with water and detergents on a daily basis. Excessive moisture in the flooring system can lead to discoloration ofthe joint materials and the stone, particularly if the stone flooring material is absorptive. Moisture ca

46、n become trapped below highlypolished finishes and appear as a stain. Some stone types used as flooring may need to be treated at the edges and bottom surfaceas well as the top surface to limit absorption-related concerns. However, component compatibility should be researched or testedprior to treat

47、ing these surfaces to inhibit bond performance between the stone, adhesive, and grout. Only cleaning procedures andproducts (including waxes and cleaning agents) that are approved for use by the stone supplier should be used. Unapprovedmethods may stain or damage the stone or damage the stone finish

48、.17. Stairs17.1 The use of stone for stair treads and risers leads to an attractive, durable, and low maintenance way to address interiorelevation changes. Stone selected for stairs should be able to withstand constant foot traffic with minimal surface abrasion, erosionor damage. It should also be n

49、aturally slip-resistant due to the stone type or the finish selected.18. Cladding18.1 Stone used as interior wall cladding should be designed and installed in a similar manner to exterior wall cladding;however, loading considerations are different with an interior application. When considering stone anchorage options for an interiorapplication, one should include (at a minimum) a nominal differential pressure on interior stone resulting from variations inbuilding pressurization due to mechanical system performance and air loss through the building enclosure; however, it is
