Compressive Strength
of SAWDUST as an
Alternative Fine
Aggregate OBJECTIVE OF
THE STUDY •To develop lightweight
and cheap
concrete mixture. • To determine if
sawdust cement
can be used in •To recycle the waste
byproduct of sawmills. This study has the
following objectives: STATEMENT OF
THE PROBLEM it aims to answer the
following questions: How can we have a
lightweight and cheap
concrete mixture? Is sawdust cement
can be used in CHB,
SLABS & COLUMNS? How can waste byproduct
of sawmills be recycled? INPUT PROCESS OUTPUT Sawdust
Cement
Coarse Aggregate
Water Concrete mixing
Fill the mold with
3 layers of concrete.
Rod each layer with
25 strokes of the tamping rod.
Curing of specimen for
7, 14 and 28 days Compressive strength

Cheap and lightweight concrete Table 2: Compressive strength (PSI) of a
sawdust mixture with a ratio of 1:1:2 Table 3: Compressive strength (PSI) of a
sawdust mixture with a ratio of 1:1(1/2):3 METHODOLOGY Research Design/Research Method The researchers will use experimental method and
secondary source like website, library and observation
which is related to the study. Locale of the study/ Research setting DPWH SAN ISIDRO 4th DISTRICT
(Department of Public Works and Highways) Research instrument Observation
Internet research Data- gathering Procedure The researchers will now gather materials
for concrete mixture and treat it for 28 days
and test it for 7, 14 and 28 days Data Analysis /
Statistical Treatment of Data The gathered data from the test will be graphed
depending on the result of the test using a line graph. SUMMARY Developing SCOPE AND DELIMITATION
OF THE STUDY This study will be held in the DPWH San Isidro
4th District Engineering Office (Department of Public
Works and Highways) and focus on the
compressive strength of sawdust cement RECYCLING SAWDUST Compressive

and
28 Days Tested Hydraulic Press
Machine POSSIBLE Non-Bearing
Load Bearing
Loads Compressive Strength of
CHB for non-bearing loads 300 PSI Compressive Strength of
CHB for bearing loads 500 PSI NSCP standards CONCLUSION Sawdust cement can be used in
Concrete Hallow Block (CHB)
bearing and non-bearing.
Sawdust cement can’t be
used in Columns and Slabs
(ground or Upper).
Sawdust concrete is
NOT fire hazardous. Sawdust is an ideal filler material
to produce lightweight concrete blocks RECOMMENDATION Volume stability related
to moisture and load Insulation properties Tensile and Elastic properties Moisture condition of sawdust Applying casting pressure POTENTIAL
