“…Straw can be used in the construction industry as blown insulation [13], prefabricated straw wall panels [14,15], or self-supporting straw bales [16,17]. Another possible application of straw in the construction industry can be various composite structural elements, for example, in the form of straw-fibre cement composite [18,19].…”

The importance of green and sustainable materials in civil engineering is undeniable. Alongside modern practices that improve the properties of standard building materials, there are ways to revive forgotten techniques, including straw bale buildings. Straw bales are load-bearing structures, which are applied based on handed-down experience and lack standard approaches in testing, design, and application. Therefore, a goal ahead is to describe every aspect of the process in technical detail. The objective of this paper is to highlight practical ideas for testing straw bales on a hydraulic press machine and to provide a basic statistical investigation of the results obtained. Two basic series were prepared, one without a side barrier and the other with a side barrier. The reason for this was to delineate the limits of the real behaviour of the straw bale on the load bearing wall of the house. Due to the assumed slight embedment of adjacent bales, the real result were within these limits. The experimental plan, basic results, simplified correlations, and statistical evaluation are presented. Recommendations for a further testing and evaluation are provided. As expected, the results with and without the lateral barrier differ by almost 18% for the true strain.

“…The case of the compressed straw panels wrapped in recycled paper was then analyzed [38,39]. A crucial aspect of these panels is their low embodied energy, together with the fact that similar products are currently produced in Rwanda with the deep involvement of local farmers in the production of straw [40].…”

Sustainable Solutions for Mass-Housing Design in Africa: Energy and Cost Assessment for the Somali Context

et al. 2021

Today, the main issue of providing adequate and affordable housing is to go beyond the mere offer of basic shelters, intending to create sustainable and durable settlements. Due to the fragile and uncertain nature of its social, political and economic context, characterized by the lack of common shared legislative references and business strategies in the housing sector, Somalia is a challenging reality to be explored and improved. This paper describes the outcomes of the BECOMe project, intending to propose sustainable solutions for mass-housing design for new sustainable settlements in Mogadishu, involving local entrepreneurs, social organizations and renewable energy. In detail, social, environmental and economic key sustainability requirements (KSRs) for mass-housing are identified first. Then, the most appropriate climate-responsive design and construction technologies at the building level, tailored to the Mogadishu context, are selected; the outcomes are applied to a specific case-study building, assessing energy and cost performances to pave the way for implementation projects in Somalia.

Sustainable development in civil engineering is the clear and necessary goal of the current generation. There are many possibilities for reducing the use of depletable resources. One of them is to use renewable and recyclable materials on a larger scale in the construction industry. One possibility is the application of natural thermal insulators. A typical example is a crushed straw, which is generated as agricultural waste in the Czech Republic. Due to its small dimensions and good thermal insulation parameters, this material can also be used as blown thermal insulation. The research aims to examine the fire resistance of crushed straw as blown insulation. The single-flame source fire test results, thermal attack by a single burning item (SBI) test and large-scale test of a perimeter wall segment are shown. The results show that blown insulation made of crushed straw meets the requirements of fire protection. In addition, crushed straw can be also used to protect load-bearing structures due to its behaviour. This article also shows the production process of crushed straw used as blown insulation in brief.
