Abstract
This research was to study the mechanical and thermal properties of fired clay brick
from five different states in Malaysia. Mechanical properties are determined by the
behaviour under applied forces using mechanical test. Thus, provides the basic for
predicting behaviour of materials under different load condition and designing the
components out of them. Thermal properties are those properties of a material which is
related to its conductivity of heat. The quality of fired clay brick from different factory
varies due to the different method of a manufacturing process. This is one of the main
contributing factors for the problem which is to identify the best manufactured fired
clay brick and how to improve the quality of the existing fired clay brick produced.
Besides, the temperature often becoming the most important factor to maintain the
optimum indoor thermal comfort when the humidity is kept at around 50% with absent
of air movement. The experiment were conducted including water absorption test,
compressive strength test, flexural test, thermal test, density test and non-destructive
test Ultrasonic Pulse Velocity (UPV) of the fired clay brick from five different states.
Based on the result obtained, the fired clay brick from Rantau Panjang, Kelantan shows
the highest compressive strength than other fired clay brick. Besides, it has the higher
flexural strength, and lower water absorption which tend to produce the good quality of
brick. Moreover, the value of the hardness tests which Ultrasonic Pulse Velocity (UPV)
was higher than other brick. The higher compressive strength and flexural of brick
consists of low water absorption due to less porosity. As a result, the thermal
conductivity decreases with decrease in density and increase in fired clay bricks
porosity. As conclusion, the best quality of brick from five different states in Malaysia
was brick from Rantau Panjang, Kelantan.
