ABSTRACT
Motivated by a persistent need to produce a sustainable and eco-friendly construction unit, an experimental investigation was undertaken to explore the durability of a new alternative fly ashwood fiber masonry block. The block's ability to resist different weathering actions was investigated by performing different tests. Masonry construction has been used for many years in a variety of structures. The masonry of ancient time's consisted of two major materials: brick and natural stone. Brick units historically have been manufactured from sun-dried mud or burned clay and shale. Clay and concrete are widely used in masonry units as a construction material. A number of researchers have focused on the use of by-products in the construction and masonry arenas. The experimental test was presented for compressive strength, pulse velocity, density and surface hardness of fly ash blocks. The wood fiber-fly ash masonry unit exhibited excellent resistance to freeze-thaw cycles as compared to conventional concrete masonry unit.
