The strength durability cost and aesthetics of a structure are all greatly impacted by the building materials used in the construction industry. Bricks and blocks are among the materials that are used the most. The basic building blocks for walls partitions and other structural components are these units. Numerous varieties of bricks and blocks are available each with special qualities and uses. Brick Types: 1. Bricks made of clay (burnt bricks) The most widely used and conventional bricks in construction are made of burned clay. Clay is molded into a rectangular shape dried and then fired in kilns to create them. These bricks are robust long-lasting and appropriate for all kinds of buildings. They are categorized according to their quality into four grades (Class I to IV). 2. Bricks made of Fly Ash Fly ash cement gypsum and lime are the ingredients used to make fly ash bricks. Compared to clay bricks these environmentally friendly bricks are lighter have smooth surfaces and provide su...
In construction, slabs are the horizontal structural elements that provide a building’s floors and ceilings. They are essential for giving a flat surface, supporting weight loads evenly distributing the weight to the foundation. It’s necessary for Architects, Engineers, and Builders to understand the various types of slabs in construction to choose the right type of slab for the different applications Here we will know about the type of slabs, their characteristics, and their uses in the construction.
Types of Slabs in Construction
They are simple mobile, table, without beam slab. Flat slabs
provide a suitable for multi-story units, parking garages, and commercial
buildings, as well for their reduced formwork requirements, and also for their
efficiency in case of the use of space. Flat slabs provide easy changes to
layouts and give a smooth, flat ceiling. As for the material it could be a
steel reinforced or not. In terms of bending moments and shear strength, flat
slab are typical needs.
One way slabs that are supported on the two opposite sides,
so the loads are carried by the short span of the slab. This kind of slab is
used in areas which are rectangular shape where the long side is greater than
twice the short side. these are recommended for structures like residential
buildings, offices and where simple support arrangements are required. They are
definitely efficient (can take a distributed load) where spans are small to
medium.
Two Way Slab is supported on all four sides like a plate and
they carry the load in both directions. This type of slab will generally be
suitable to a square or nearly square spaces where the length to width ratio is
less than two. These kinds of slabs are deeply used in the large floor areas of
commercial buildings and hall slabs. They contribute for better load
distribution and higher structural integrity for longer spans compared with
one-way slab. Ex. 1 Two Way Slab
Hollow core slab is the most often used precast concrete slabs
with continuous voids or cores running through it. The voids are formed in
hollow core slabs in order to reduce the weight and improve the thermal and
acoustic properties Hollow core slab systems are ideal for maximum spans on
ground floors in residential, commercial and industrial buildings. They are
famous because of easy and fast installation and their effectiveness in terms
of cost. And today they find widespread use in contemporary construction.
Precast Slab
Precast slab is manufactured offsite and delivered directly
to the construction site ready to be installed. By this method we achieve
higher quality control, quicker construction time and take advantage of
different materials for precast slabs. These apply on the most massive
structures like parking structures, bridge decks and high-rise buildings. They
can be tailored to meet specific design requirements, they are resistant and
stay reliable for good time.
Composite Slab
Composite slabs are a combination of steel decking and
concrete that utilize a lightweight, environmentally friendly, sustainable
deck, excellent for medium to heavy loads. These are very common in
multi-stored buildings, where the profiled metal deck provides a permanent
solution to formwork and acts as tensile reinforcement to the slab. They have
high load carrying capacity and require less formwork than other slab forming
solutions, making them cost effective and practical.
Waffle Slab
Waffle Slab is one consisting of ribs in two orthogonal
directions and the waffle thickens is fastened together by thin web of concrete
thus making a waffle appearance. The construction is diff than a one-way slab-
they are more ridged since the rib repeats. Mainly used in the areas such as
auditoriums, halls, commercial buildings where there is minimum span of beams
and the understory space is a major Institute of the Industrial Buildings
Auditoriums and Hall Their attractive appearance and greater structural
efficiency...
Post-tensioned slabs involve high strength steel tendons
that are stretched after the concrete is set and have been gaining strength.
This results in increased loadbearing capacity of the slabs and makes it
suitable to greater spans with reduced thickness of slabs. These will be used
in multi stored buildings, parking structures and bridges.
Finally, the type of construction slabs can tell us a lot of
what is required for its structural performance, efficiency and aesthetics.
Whether it's a flat slab to composite slab, each variant comes with its own set
of benefits and applications. By choosing the right type of slabs it can
further assure safety, functionality and long life of the structure ensuring a
better fulfilment of its intended use.
