摘要：Interlocking Hollow Block System (IHBS) is a reasonable solution for conventional block masonry due to its structural ability and building capability. In addition, economic and ecological building of brickwork can be achieved by incorporating fly ash into IHBS. The main aim of the research is to produce interlocking compressed hollow block that satisfy the standard requirement as in Eurocode 6. The study is essentially divided into 2 phases, block production and block compression testing. This paper studies on the compressive strength of interlocking hollow clay block with various compositions including laterite soil, cement, sand and fly ash. The optimum mix design is achieved with minimum compressive strength of 7 MPa, which comply with the standard BS 5628-1:1992 Code of practice for Use of masonry – Part 1: Structural use of unreinforced masonry. Test result on addition of fly ash revealed that the optimum fly ash content was 2% with the highest compressive strength of 10 MPa. The results of this study show that the proposed block mixture meets the standard strength requirements and the structural performance of the masonry block is improved by adding fly ash into the mix design.
