| dc.description.abstract | Compression when tested on compressive testing each brick has its own strength all brick
does not have an equal or similar strength to each other. Compressive strength is also
known as compression strength. Compressive strength is the capacity of a material or
structure to with tend loads tending to reduce size, as opposed to tensile strength, which
with stands loads tending to elongate. The objective of this experiment is to determine the
compressive strength of brick sample. "Conducting this experiment, we can obtain the
strength of the brick. This experiment their area few methods that have been used.
Compressive strength of bricks is the capacity of brick to resist or withstand under chine .
The Compressive strength of a material is determined by the ability of the material to resist
failure in the form of cracks and fissure.
Compression when tested on compressive testing each brick has its own strength all brick
does not have an equal or similar strength to each other. Compressive strength is also
known as compression
Concrete Block (CB) brick is a material composition for wall building made of Portland
cement, water, and fine aggregate blended with a foaming agent. The weight of the brick
is light due to the air cavities formed in the Concrete Block brick. The number composition
of sand and cement in the Concrete Block brick could improve the strength of the bricks.
Thus, it is essential to find out the sand and cement consumption in order to improve the
rate of brick strength. The study aims to improve the strength of the Concrete Block bricks
with the different composition of the material and to find out the index properties of the
bricks with the variable component of the materials. The study used an experimental work
in the material laboratory with two variations of the material composition. The first
variation is mixing concrete for the ratio of cement and sand of 1:2, while the second
variation is mixing concrete for cement and sand ratio of 2:3. The wet density of the
Concrete brick is about 800-900kg/m3, and the average compressive strength test was
conducted at ages 3, 7and 28 days for each test. Three identical specimens were prepared
for each test. The study resulted in the 28-day strength of the Concrete brick with a mass
ratio of cement to sand 1:2 of 0.52 MPa, and the strength of the brick with a mass ratio of
cement to sand 2:3 was 0.68 MPa. The first variation was lower by 24.5% than the second
variation in terms of strength. The higher cement consumption used into the mixed can
make porosity of the specimen decrease, and then the strength of the specimen will improve
