Tiivistelmä
The main aim of this Bachelor's thesis was to examine and to propose a prototype design of highway noise barrier wall, which is made from Hempcrete, a hemp-lime composite material. The thesis was commissioned by the company Hemprefine Oy, with the participation of HAMK University of Applied Sciences.
The possibility of constructing such structure was assessed and evaluated. In addition, advantages and disadvantages of a Hempcrete noise barrier wall prototype were discussed. Hempcrete and concrete were also compared.
The prototype design of the Hempcrete noise barrier was made according to the concept of environmentally friendly green structures. It consists of a timber load-bearing frame; four Hempcrete blocks, connected to each other; and foundation, which is chosen according to the geotechnical aspects of construction site. Based on the various researches, it was concluded that the construction of the Hempcrete noise barrier in the targeted area (Finland) is difficult due to the excessive water absorption by Hempcrete. Its implementation requires deeper studies and testing of the durability and resistance of the material in the Finnish climatic conditions.
As a conclusion, it can be stated that the presented prototype of Hempcrete noise barrier wall is eco-friendly, sustainable structure with the ability to sequester carbon dioxide and unique sound absorption properties, that can be successfully used in countries with a dry climate. Such structure can contribute to the development of environmental and sustainable road construction.
