In the context of rapid urbanization, poverty, dense habitat and mass housing, cost effective, light weight and easy technology is being much looked for. Ferrocement, which is a versatile, lightweight, thin material and involves easy labor, is emerging as an effective building material in the construction industry. This paper illustrates the diversified application of ferrocement in various construction works undertaken by housing and Building Research Institute in Bangladesh. Several projects are demonstrated here with prominence to diverse ferrocement elements serving as both structural-non structural components of a building and serves aesthetic purpose as well. Application of ferrocement in different type of roofs and slabs, partition walls, louvers, poles, pavements and even structural components like columns and beams are depicted in the write up. Aim of the study is to explore the versatility and effectiveness of ferrocement in construction. Thus the paper intends to manifest the potentialities of the rising construction element and its juxtaposition with the conventional ones.

The cast in situ construction process on a smaller scale pilot project including materials and the steps of workmanship will be explored in this paper. The sandwich panels consisted of two thin ferrocement layers reinforced with one layer of woven wire mesh. The core was about 56.25 mm thick and made of lightweight expanded polystyrene sheets. Steel wires were used to tie the two layers of iron meshes together. A total of 100sft sandwich panel was constructed. The proposed panels are lighter in weight relative to the conventional brick walls. This kind of lightweight construction process could prove to be a true merit for a developing country like Bangladesh.

The raw materials obtained from three sources such as Kapotakkho River, Brahmmaputra River and also some soil had been collected from Housing and Building Research Institute (HBRI) Campus. The complete project was divided into two broad phases. The first phase included the determination of the optimum percentage of stabilizer (cement). The considered measuring criteria were water jet test, submersion test, modulus of rupture, and compressive strength test. According to the tests, 10% cement mixed with dredged soil proved to be viable option for economical and durable blocks. In the second phase, CSEB was prepared with adding sand (Brahmmaputra soil) and Jute fiber as reinforcement. Different type of curing like air curing, sun curing and polythene wrapped curing were incorporated and tests were conducted on third, seventh, fourteenth and twenty eighth day. The observations affirmed that each composition has its own superiority to others on particular area. For example, CSEB made from HBRI soil and cured at natural air can bear more compressive load where Kapotakkho-Brahmmaputra soil cured at sun is less susceptible to moisture absorption. The Jute composition with Kapotakkho soil cured by natural air form less brittle blocks than any other types of CSEB tested in the laboratory.
