“…It was also observed that the 9-year-old reed (Gena Ndorom) had 23.53 x 10 4 N / m 2 lower tensile strength than the 7-year-old Gena Jengkong x 10 4 29,74 N / m 2 and the 5-year-old Gena Mandok 32,38 x 10 4 N / m 2 which is heated every day and heated. These results do not show the same trend as the Dosdall study [10] which suggests that there is an increase in the value of bending strength and the limits of elasticity of reeds in the 120-160 0 C temperature range. From the daily treatment of reeds in Wae Rebo, it is seen that the heating in the traditional house aims to drain the reeds so as not to damp, but if the heating is done at temperatures above 160 0 C, it can decrease the tensile strength of reeds.…”

“…Troya research [7] about the endurance of reed materials as a noise barrier in Vienna and Briscke [9] about the comparison of reeds treated thermally to reduce the growth of fungi and can decay the reeds and end the lifetime caused by moisture. Dosdall [10] also tested the strength of reeds material by heating at temperatures between 100 and 140 ° C for 2 hours and not only against weathering due to the fungus but also improving the material's resistance to bending strength and natural technical elasticity.…”

The use of natural materials in traditional architecture has the advantage that the natural resources are owned together by the people living around the resources, the distance is not too far away from the settlement, the extraction resource’s process didn’t spend a lot of energy, and it’s more environmental friendly because easy to decompose and return to nature. Natural material as an element in traditional architecture become important as part of architectural research, not only to preserve the form, but also to pass on local knowledge about the traditional architectural construction process. One of the dominant materials for building’s roof located on small islands along the banks of the Indian Ocean is reed roof. It is derived from tall grassshaped grasses with the latin name Imperata cylindrica. This study aims to explore the material’s potential of reeds as a local identity by tracing local-based techniques/indigeneous utilization of reeds in traditional architecture in Indonesia. By tracing the way the reeds are utilized, we can find technical performance that makes the reeds useful as building materials that survive for hundreds of years which is also known of the life cycle process. The methods were by doing interviews and observation at traditional settlements at Wae Rebo and by measuring the reeds’ performance in each cycle of life cycle so that we could identify the causes of reeds decay. From these methods it would be revealed how humidity influenced at each stage of the life cycle ranging from extraction to maintenance, and to the strength of reeds. The traditional treatment on the process of the reeds maintenance could reduce moisture and extend the life of the reed roof.

“…Since it does not absorb water or moisture due to its silicon covering, the stem, in particular, is used in the construction of walls, partitions, fences, roof hatching, and as an insulation material [38,39]. Further, heat treatment of Phragmites samples have shown that drying at 120-160 • C increases its flexural strength and the technical elasticity limit, highlighting the potential of Phragmites in the production of cost-effective lightweight concrete blocks and as feedstock for construction materials [40].…”

The Effect of Adding Phragmites australis Fibers on the Properties of Concrete

et al. 2022

Nowadays, the increasing demand for concrete is causing serious environmental impact including pollution and waste generation, rapid depletion of natural resources, and increased CO2 emission. Incorporating natural fibers in concrete can contribute toward environmental sustainability. This paper is concerned with the use of natural fibers obtained from the plant species Phragmites australis (PA). The plant is invasive, and rapidly grows abundantly along rivers and waterways, causing major ecological problems. This research is part of a wide range investigation on the use of natural fibers produced from the stem of PA plants in concrete. Using a machine, plant stems were crushed into fibers measuring 40 mm in length and 2 mm in width, and treated with 4% NaOH solution for 24 h. A total of four concrete mixes were prepared with varying additions of treated fibers, ranging from 0% to 1.5% (by volume) with water to cement ratio of 0.5% (by volume). Concrete specimens were tested at 3, 7, and 28 days. Testing included compressive strength, density, total water absorption, and capillary water absorption. The results show that incorporating PA natural fibers reduces the water absorption by total immersion and capillary action by up to 45%. Moreover, there is a negligible decrease in concrete density and strength when fibers were added. It is concluded that adding up to 1.5% natural PA fibers to concrete is a feasible strategy to produce an eco-friendly material which can be used in the production of sustainable building material with adequate mechanical and durability performance.

“…Experiments with heat treatment have demonstrated that drying Phragmites samples at 120–160 °C increases their flexural strength and the technical elasticity limit [ 25 ]. This finding might be of interest when designing products derived from reeds, such as in [ 26 ], where the good parameters obtained for lightweight concrete blocks along with rising industrial demand for cost effective, lightweight and robust insulating materials suggest that Phragmites have great potential as feedstock for building materials.…”

Characterization of Mechanical and Hygroscopic Properties of Individual Canes of Reed

The search for sustainability has led to the utilization of more ecological materials with at least, a similar structural performance to those used at present. In this regard, reed fits the environmental and structural requirements as it is a sustainable and biodegradable lignin-cellulose material with remarkable mechanical properties. This research confirms the reed’s structural efficiency as it demonstrates that it has excellent strength and stiffness in relation to its density. The reed anisotropy has a large impact on its properties. Indeed, the strength and stiffness parallel to the fibers are clearly higher than in the perpendicular direction. The results confirm that strength and stiffness decrease with the moisture content and nodes act as reinforcement in compression and bending. If compared with steel, timber and concrete, the reed possesses the highest value for strength. Hence, reed constitutes a strong candidate for environmentally friendly engineering.
