WHAT IS MATERIAL?Material is key factor fM t i l i k f t of any product. d tBasically material can bB i ll t i l be d fi d as an definedingredients which are use to form a particularproduct.The material which are used in constructionwork are called construction materials orbuilding materials. e.g. Stone, Brick, Aggregate, Cement,Mortar, Concrete, Lime, Metal, Glass, Paint,Timber etc etc. 3

Requirements of Building Materials Service Fabrication Economic EnvironmentalRequirements Requirements Requirements Requirements
SERVICE REQUIREMNTSMaterial should satisfy its own properties like size size,shape, colour, strength, stiffness, durability,chemical composition, corrosion resistance etc.Material should easy to handle.Material should easily available in nearby area area.
FABRICATION REQUIREMNTSFabrication process refer to how a material iscreated, processed and assemble.Material should easily fabricated as perrequirements. q e.g.: Metal should be easily casted, forged, machined, rolled and cut.
ECONOMIC REQUIREMNTSMaterial should be of good qualityIts initial cost, transportation cost andmaintenance cost should be affordable.
ENVIRONMENTAL REQUIREMNTSMaterial should create minimum pollution.It should not react with chemical or anysubstance presence in environment environment.It should b able t b h ld be bl to bear weathering affects. th i ff t

TYPE OF STRUCTURES Type of Structure Load Framed Combined Bearing B i Structure StructureStructure
LOAD BEARING STRUCTUREFoundation is constructed beneath the walls walls.Load is transmit by load bearing wall to sub-soilthrough its foundation.There is no column is constructed.Wall thickness: 20,30, or 40 cm.Maximum 3 storey are permitted.M i t itt dIt is adopted where soil strata is hard at shallow depth.With the increases in no. of floors, wall thickness isdecreases.
FRAME STRUCTUREMain structural members are Beams & Columns Columns.Beams support the wall & slab.Foundation is constructed beneath the columns onlynot beneath the walls.Its self weight is less in comparison to load bearingstructure.structureIt is easy to construct.
COMPOSITE STRUCTUREColumns as well as load bearing masonry walls areprovided.Load is transmitted to sub-soil by both the members.It is proffered for construction of floors which has tocover large area by slabs like exhibition hall, godowns,public buildings etc etc.
