Study on the different arrangement of brick masonry wall between three type of bricks

Abstract

This project presents the result of brick masonry strength depends on different bonding follow by the type brick and to determine the crack pattern at the masonry wall. The arrangement was used in this research is stretcher bond and stack bond. There were three types of brick was used in this research which is clay brick, sand brick and modified sand brick using coconut shell. Six specimens were used in this research where three types of brick for stretcher bond and another three types of brick for stack bond. The ratio for mortar mixture is 1:3 which is one for cement and three for sand. The test was used is compressive strength. This test is to compare compressive strength between arrangement of brick and types of brick. It is also to determine the crack pattern of brick masonry arrangement. The fixed time purposed is 20 seconds during the test of compressive strength before getting the maximum reading. This test was done by referring BS 1881-118. The stretcher bond of brick arrangement was stronger where the highest value stated at 2.24 kN compared to stack bond with only 1.49 kN. Similarly, clay brick was stronger with 2.24 kN than sand brick with 1.71 kN and also modified sand brick using coconut shell with only 1.55 kN. For crack pattern, the stretcher bond was crack at the part of the mortar and brick. However the crack pattern for stack bond was happen at the mortar.
