This document summarizes a project on producing lightweight concrete using wooden powder. Various mixtures were tested by replacing sand with wooden powder at percentages ranging from 5% to 25%. Testing showed that as the percentage of wooden powder increased, the weight and compressive strength of the concrete cubes decreased. The greatest weight reduction of over 30% and strength reduction of over 95% was observed when sand was replaced with 25% wooden powder. The study concluded that wooden powder can effectively reduce the weight of concrete but also reduces the strength, with higher replacement percentages causing greater strength loss.

4. INTRODUCTION
LIGHT WEIGHT CONCRETE
 Lightweight concrete can be defined as a type of concrete which
includes an expanding agent in it that increases the volume of the
mixture while reducing the dead weight.
 It is lighter than the conventional concrete with a dry density of 300
kg/m3 up to 1840 kg/m3.
 The main specialties of lightweight concrete are its low density and
low thermal conductivity.

5. WOODEN POWDER
 Saw dust is also known as wooden powder
or wooden dust. It is the by product of
cutting, drilling, grinding, sanding wood .
 It is produced as a small irregular chips or
small garbage of wood during sawing of
logs of timber into different sizes
 It is also the by product of certain animals,
birds and insects which live in wood, such
as the woodpecker and carpenter ant.

6. TYPES OF LIGHT WEIGHT CONCRETE:
Using lightweight aggregates: This type is produced using lightweight
aggregate such as volcanic rock, wooden powder or expanded clay. It can
be produced with the use of naturally mined lightweight aggregates (bulk
density in the range of 880 kg/m3) or manmade lightweight aggregates like
“Aardelite” or “Lytag” (bulk density 800 kg/m3).
Using foaming agents: This one is produced through the addition of a
foaming agent in cement mortar. This creates a fine cement matrix which
has air voids throughout its structure. Aerated cement mortar is produced
by the introduction of a gas into cementitious slurry so that after hardening
a cellular structure is formed.

LITERATURE REVIEW

11.  H. S. Sureshchandra, G. Sarangapani, and B. G.Naresh Kumar
 The properties of mortar were investigated with the replacement of 25% and
50% of fine aggregate this work has indicated that 25% replacement level
exhibit higher strength than the controlled sample.
 The compressive strength of concrete is found to decrease with the increase in
wooden waste content.

 Important oxide content was 65.45% by weight of SDA and has a pH value of
11.12, which shows that it’s alkaline in nature

14.  As per now, we have created natural concrete cubes of size 15x15x15cm
by the help of cement ,sand and natural aggregate.
 The mixes of grade M20 correspond approximately to the mix proportion
(1:1.5:3) respectively.
 With the help of molds we have created cubes and after that we have
calculated the weight of natural concrete cubes for comparison and then
The compressive strength of the cubes have been recorded with the help
of compressive testing machine.
 After completing natural concrete cubes we shifted our focus on making
concrete cubes with the help of wooden powder by replacing sand by
5%, 10%, 15%, 20% , 25% and curing and results have been obtained.

33. CONCLUSION
As we replaced sand by wooden powder in different proportions
we conclude that the weight and strength varies accordingly. As we
increase the percentage of wooden powder the weight of the cube
decreases, but accordingly characteristic compressive strength also
decreases rapidly. As per our observations we found that
I. In M-20 the strength of concrete decreases as in increase in
proportions of wooden powder.

34. SCOPE OF THE WORK
a) Use of saw dust and by sand replacement in normal
concrete for real time projects thereby reducing
the overall cost of construction.
b) Reduction in mining river sand helps protecting the
ground water table.
c) The effective way of utilising waste material leads
to clean environment.
