How To Calculate Quantity of Blocks ?

How To Calculate Quantity of Blocks.

Volume of wall = L x B x H

= 6 x 0.152 x 3 = 2.736 cum.

Volume of One Block Without Mortar = 0.405 x 0.152 x 0.200 = 0.012312 cum.

Volume of One Block With Mortar = 0.430 x 0.152 x 0.225 = 0.014706 cum.

No of Blocks = Volume of Wall / Volume of One Block With Mortar

= 2.736 / 0.014706 = 186 Nos Blocks

Volume of Total Blocks = No's of Blocks X Volume of One Block Without Mortar

= 186 x 0.012312 = 2.290032 cum.

Volume of Mortar = Total Volume - Volume of Blocks

Wet Volume = 2.736 - 2.290032 = 0.445968 cum.

Dry Volume = Wet Volume X 1.27

= 0.445968 x 1.27 = 0.56637936 cum

Cement Mortar Ratio = 1:6 Ratio

Cement = Ratio of Cement X Dry Volume / Sum of Ratio

= 1 x 0.56637936 / 7 = 0.08091134 cum.

Bags = 0.08091134/0.035 = 2.31 Bags

Sand = 6 x 0.56637936 / 7 = 0.48546802 cum.

Say = 0.5 cum.

The loads Acting on staircase.

Distribution of Loads and its Effect on Staircase Stair slabs are usually designed to resist gravity loads , comprising of dead loads and live loads as described below: 1) Dead Load : The components of the dead load to be considered are: a) Self-weight of stair slab (tread/tread-riser slab/waist slab) b) Self-weight of ... LIVE LOADS:- IS 875 parts II specifies the load to be considered as UDL of intensity 5KN/m2 for public buildings and 3kN/m2 for residential building where the specified floor do not exceed 2kN/m2 and the staircases are should not liable for overcrowding. DEAD LOADS:- Self-weight of stair slab which includes the waist slab, tread-rise,etc. Self-weight of finishes (0.5 to 1 kN/m?) Types of stairs ...

Medlum Density Fibre Board (MDF)

Medium Density Fibre Board (MDF) MDF IS made from wood and other lignocellulose material refined into fibres and reconstituted with a resin binder. Row wood material is normally a single species wood. MDF has homogeneous structure with uniform density, texture and properties throughout, no identifiable grain can be seen at edge, end or face. There are no internal voids or pits and there is no variation in the surface hardness. Unlike plywood MDF doesn't delaminate. It has much higher strength than particle board. Since edges are totally smooth and uniform, costly tipping or beading with strips of wood required for plywood and particle board is not essential. It can be carved, grooved or embossed just like any timber. The surface of MDF is totally smooth and accepts all kinds of finishes - paints, varnishes and laminates. One such type of famous board in the market is 'Duratuff" . It comes in both interior and exterior grade. Duratuff prelaminated boards are also avail...
