HOW TO FIND THE MEAN GIRTH OF THE SIMPLE BUILDING

Image
Mean girth of building , this is the centerline perimeter or circumference of the building, which describes length of the building. The following text show how to find the mean girth of simple building plan shown below for superstructure walling which can help in quantity determination of different materials to be applied for paint work, plaster work, blocks or brick work. Important Terms 1. External Dimensions.   These are dimensions measured from      external surface of the building's walls, these always show the extent of building on plot. 2. Internal Dimensions. These are dimensions measured from internal surfaces of the building walls, these always show sizes of rooms. 3. Corner. These are interconnection or points where two non colinear walls meet. 4. Recesses. There are the partition or adjoining walls which forms rooms or which were not considered in exterior girth of building determination. Ti...

HOW TO CALCULATE AMOUNT OF MORTAR PER S.Q.M FOR BLOCK WALL

Image
HOW TO CALCULATE AMOUNT OF  MORTAR  PER S.Q.M FOR BLOCK WALL The amount of cement paste required as mortar per square meter can be calculated through the following steps 1.       Knowing the dimension of the blocks to be used for construction. Here, let’s say we use the cement concrete block of size 150 x230 x450 where by 150 s the thickness of the wall. These dimension s (all dimension are in mm) help to find the area of one block forming wall surface as follows Area of one block = 230 x 450                              = 103,500mm 2 2.        Knowing the new dimension of blocks with cement mortar. New dimension of concrete block means the height and length of a block with the thickness of mortar which is 15m, then the new height id 245mm and new length is 265mm Fr...

REINFORCEMENT IN CONCRETE

Image
In construction industry different structures are built, the built structures can be categorized with accordance to construction materials, here we can have steel structures , timber structures and concrete structures. Concrete structures are the one which most of its structural parts made from concrete material , concrete is the most and widely used material due to its ability to be moulded into different shapes , and having wide range of characteristics (economical concrete of variety properties can be produced for different requirements). Concrete has high compressive strength , that make concrete made structures to have high capability to withstand compression, cement concrete has low tensile strength that make it unsuitable for structures subjected to high tension. Due to some weakness and properties of cement concrete, it is reinforced so as to produce a structure with required properties. Concrete can be reinforced by different kind of materials in different ways per given a...
