Introduction
:
Established in the year
1985, with objectives of introducing a high
quality construction product, Aeon's has since
grown to become a path maker in the construction
industry in India. "ECMU" was introduced in
India by Aeon's.
Aeon's consistent efforts and regular R & D
work continues to provide high quality and innovative
solutions to the construction industry.
About
ECMU :
®
Engineered Concrete Masonry Units (ECMUs)
are hollow and solid blocks used for a variety
of industrial/residential applications replacing
the burnt clay bricks. ECMUs cover a range of
basic structural elements such as walls, columns,
pilasters, beams, lintels and retaining walls.
The units are manufactured in a variety of structural
grades, facade designs, textures, colours, shapes
and sizes.
What
is SAP?
®
(Structural, Architectural & Pre Engineered)
is an innovative Engineered Concrete Masonry
Unit (ECMUs), a modular construction product
used as primary construction material for all
kinds of buildings. SAP is an advanced construction
product that altogether eliminates the need
to use bricks and helps you build to international
standards and style. It is the outcome of extensive
research in USA to satisfy demands of the construction
industry. ECMU as a premium product has in a
short span of time edged out most of the conventional
building products and constitute more than 80%
usage of construction in USA and other advanced
countries.
®
satisfies ECMU needs of varying applications
in the construction industry such as structural
soundness, versatility, architectural freedom
and aesthetics, ease and speed of construction,
durability, performance standards, style, living
comfort and economy.
The
Technology
®
is a high technology product manufactured under
strict quality control conditions in a modern
plant equipped with state of art machinery that
includes rugged casting and stripping machines
with the latest moulding techniques. This kind
of technology provides for control of following
parameters of the product while under manufacture
as per the requirements of the customer:
| Size |

Properties |
The
strength and properties of SAP
are achieved by a judicious interplay of choices
of aggregates, mix proportion, water cement
ratio, feed and finish time and so on. Designed
mix is accurately weigh batched and concrete
mix of required consistency is obtained. The
blocks are cast in the block making machines
by simultaneous vibration and compaction. Thus
SAP can be tailor made to suit any construction
requirements.
STRUCTURAL
FEATURES
®
is a structural medium, which offers the structural,
engineer two attractive features, namely structural
strength and structural form. The structural
strength of SAP Units range from 150 to 300
Kg/cm2 or higher on flange area in
compression. The strength can be further supplemented
by grouting the cores with concrete and nominal
reinforcing steel, where required.
®
has a high strength/weight ratio of about 4
to 6 times that of burnt clay bricks. This helps
the designer to design stronger yet economical
structures.
The
structural form of SAP units cover the range
of the basic structural elements viz. walls,
columns, pilasters, beams and lintels.
ARCHITECTURAL
FEATURES
®
is an architectural medium. It provides the architect
aesthetics with built in functions, thereby eliminating
the need to specify a separate medium for finishes
and rendering. SAP is available in various colors,
textures and facade designs. Plain, Single scored,
tri-scored, fluted, split fluted, striface, split face, shot blasted are some of the facade designs available.
®
also obviates the need to specify a separate
medium for functional requirements as SAP has
built in characteristic of thermal insulation,
acoustic insulation, fire resistance and resistance
to weathering.
PRE-ENGINEERED
FEATURES
®
is a Pre-Engineered modular construction unit,
which can be pre-engineered to meet varied requirements
of Engineers, Architects, Builders and Customers
to suit their specific requirements. SAP provides
for neat concealment of electro mechanical services
and plumbing integration. This gives virtually infinite
design possibilities and freedom of expression.

DESIGN
CONCEPT
The
loads from the slab are distributed on the walls
fairly uniformly. This is achieved by making
the top-most row of the blocks below the slab
into a solid portion, integral with the main
slab by using U-shaped blocks, specially manufactured
for this purpose. Horizontal loads such as wind
loads are resisted in the usual manner by treating
the slab as a diaphragm and by reinforcing the
walls at regular intervals in the transverse
direction. Where there is no eccentric loading,
the load carrying capacity of a wall constructed
using ECMU is calculated using the following
formula.
P=Cmxkx(FmxAb+Kc+Fc/1.3)
x Ac+FsyxAs)
Where
Cm = Capacity reduction factor of design strength
of reinforced masonry
(0.45 for plain Masonry).
K = Reduction factor for slenderness and eccentricity.
(0.763 for 3m
highwall)
F'm = Characteristic compressive strength of
masonry specimens (11.44
Mp2 for M30 and 9.36 for M20).
Ab = Bedded area of masonry cross section (64000
Sq.mm).
Kc = Factor for grout in compression.
Fc = Characteristic compressive cylinder strength
of grout.
Ac = Total area of grouting in the cross section.
Fsy = Characteristic strength of reinforcement.
Ast = Cross sectional area of main reinforcement
in reinforced masonry member.
ADVANTAGES
OF ENGINEERED CONCRETE MASONRY UNITS
:
Construction with ECMU
is economical than conventional building construction
due to reduction in quantity of steel, elimination
of external plastering, reduction in cement
mortar quantity and reduction in time to complete
the structure. Savings of upto 15% (approximately)
compared to bricks has been achieved using ECMU's
Economy derived in using ECMU's when used for
load bearing applications, the savings are observed
to be more than 20% due to reduction in steel
consumed by 40%, lower site over heads and reduced
other direct and indirect costs.
