In recent years paving blocks is getting widely used to complete the finishing works of many building sites as earlier as possible. paving blocks is used to prepare jogging tracks, walkways, parking spaces, footpaths etc.
In this article we will discuss about terminology about precast paving blocks.
simply, Your question about paving block, "what is mean by.....?" will be end here.
ЁЯСЙActual Dimension тАФ Measured dimensions of a paver block.
ЁЯСЙArris тАФ Part of a block where two faces meet which can be bevelled, rounded, chamfered, or splayed,
ЁЯСЙAspect Ratio тАФ The ratio of length to thickness of a paver block.
ЁЯСЙBacking Layer тАФ Layer of concrete on the lower face of a two-layer paver block, made of material same as or different from that used in the wearing тАЭlayer of the block.
ЁЯСЙBed Face тАФ That surface of a paver block which, when paved, comes in direct contact with the bedding material.
ЁЯСЙChamfer тАФ Bevelled arris.
ЁЯСЙChased Side Face тАФ The side face of a paver block, having a recessed profile.
ЁЯСЙColour тАФ Appearance of a paver block due to pigment used in concrete, other than natural cement colour.
ЁЯСЙComplementary Product -A pre-cast usually of the shape of part тАШof a block, used for fitting into gaps remaining in a block-paved area, for complete coverage of paved surface.
ЁЯСЙDraw тАФ Intended angle of the side face from the vertical plane over the full height of a paver block
ЁЯСЙEfflorescence тАФ White deposit formed on paver blocks due to diffusion of calcium hydroxide (solution slaked lime) present in cement, together with various dissolved salts, onto the external surface.
ЁЯСЙFalse Joints/Grooves тАФ Regularly shaped depressions on the wearing layer of a paver block.
ЁЯСЙFormat тАФ Work dimensions of a paver block, specified in the order of overall length, overall width and thickness.
ЁЯСЙInterlocking Mechanism тАФ The mechanism which allows adjacently paved blocks to key into one another and facilitates the sharing of shear, bending and thrust forces between adjacent blocks in a paved system.
ЁЯСЙ Interlocking/Dentated/Inter-connected Paver Blocks тАФ Paver blocks which key into one another on some or all vertical faces, when paved in any pattern.
ЁЯСЙLengthтАФ Shortest distance between farthest opposite vertical faces of a parallelepiped enclosing a paver block, excluding the dimensions due to any spacer nibs.
ЁЯСЙOverall Length тАФ The longer side of a rectangle with the smallest area enclosing a paver block, excluding any spacer nibs.
ЁЯСЙOverall Width тАФ Shorter side of a rectangle with the smallest area enclosing a paver block, excluding any spacer nibs.
ЁЯСЙPlan Area тАФ Horizontal area bounded by the vertical faces of a paver block, excluding the area due to any spacer nibs.
ЁЯСЙ Paver Block тАФ Solid, un-reinforced pre-cast cement concrete paving units used in the surface course of pavements, with minimum horizontal cross-section of 50mm from any edge in any direction, having aspect ratio not more than four, except for complementary products.
ЁЯСЙPigment тАФ Synthetic or natural colouring agents used in the-concrete mix to produce coloured paver blocks.
ЁЯСЙSecondary Processing тАФ Manufacturing process to texture the upper face of a paver block, executed before or after hardening of manufactured block.
ЁЯСЙ Side Face тАФ That face of a paver block which is generally in the vertical direction when paved and which faces adjacent block.
ЁЯСЙSkid -Resistance тАФ Resistance to relative movement between a vehicle tyre and the trafficked surface of a-pavement.
ЁЯСЙSlip Resistance тАФ Ability to resist relative movement between a pedestrian foot and the trafficked surface of a pavement.
ЁЯСЙSpacer Nibs тАФ Small protruding profiles on the vertical face of a paver block used as a device for keeping minimum joint gap while paving blocks.
ЁЯСЙSquareness тАФ Normally between the vertical faces of a paver block and the horizontal wearing surface, and parallelism between wearing surface and lower horizontal surface.
ЁЯСЙSurface Relief тАФ Regularly shaped protrusions on the wearing surface of a paver block.
ЁЯСЙSurface Texture тАФ Microscopic and macroscopic features of the wearing face of a paver block.
ЁЯСЙThickness тАФ Vertical distance between the upper face and bed face of a paver block.
ЁЯСЙWearing Layer тАФ Layer of concrete or mortar on the upper face of a two-layer paver block, made of material same as or different from that used in the backing layer of the block.
ЁЯСЙWearing Face тАФ That surface of a paver block which, when paved, faces the atmosphere and which is directly subjected to loading and movement of vehicle tyres or pedestrian traffic.
ЁЯСЙWearing Face Area тАФ Horizontal area bounded by the vertical faces of a paver Mock, minus the area reduced due to the presence of arris.
ЁЯСЙWidth тАФ Shortest distance between nearest opposite vertical faces or corners of a paver block.
ЁЯСЙWipe тАФ Fine cement mortar slurry applied to the upper face of a paver block or supplementary product.
ЁЯСЙWork Dimension тАФ Any dimension of a paver block specified for its manufacture, to which the actual dimension should conform, within specified permissible tolerances.
