“…Recently, some researchers investigated the application of sodium alginate in building and construction materials such as in cements, 46 clays, 43 and soils. 47 An increase in compressive strength from 2.23 to 3.77 MPa by adding up to 19 wt% of sodium alginate to clay is reported by Marı´n-Gala´n et al (2010). 43 …”

We synthesized cellulose/gypsum composites in the presence and absence of sodium alginate and investigated the interaction between the composite components as well as the mechanical properties of the final composites. Four different types of cellulose fiber materials were used: cellulose UFC100, cellulose B400, nanofibrillated cellulose, and Lyocell fiber. For all investigated composites the total amount of admixed cellulose was between 1 and 2 wt%, the amount of admixed sodium alginate was 0.5 wt%. We determined the morphology of the composites and observed that the particle and fiber dimensions of the admixed cellulose affect the mode of gypsum-gypsum interlocking and the total porosity of the composites. This in turn had a substantial influence on the mechanical properties of the final composite materials. The addition of sodium alginate resulted in an increase of ultimate strain values. Composites with Lyocell fiber, a synthetic fiber, also had a high Young's modulus.

“…As previously mentioned, the most detailed investigations to date are those conducted by Galán-Marín et al (2010) and subsequent studies (Galan-Marin et al, 2012;Galán-Marín et al, 2013;Rivera-Gómez et al, 2014) which discuss the use of alginate, in combination within lignin and natural or synthetic fibres, as additives for unfired clay bricks. Maximum compressive strengths of over 4 N/mm 2 are reported and it is claimed that this material could offer a suitable replacement for convential internal walling systems.…”

“…The type of alginate products used in the studies included both a liquid 'seaweed extract' (Galán-Marín et al, 2010) and a dried alginate powder (Rivera-Gómez et al, 2014) , with the authors concluding that the type of product and the specific alginate-clay interactions required further investigation.…”

Seaweed biopolymers as additives for unfired clay bricks

Unfired clay bricks are an environmentally friendly alternative to conventional masonry materials such as fired bricks and concrete blocks but their use is currently limited by their relatively poor mechanical and durability properties. While products like cement and lime are commonly added to earthen materials in an effort to improve their physical performance, these additives can also have a negative influence on the overall environmental impact. The purpose of this research is to investigate the use of alginate, a natural and renewable biopolymer obtained from brown seaweeds, as an admixture for unfired clay blocks. A total of 5 different alginates have been investigated and combined with 3 soil compositions to create prototype specimens which have then been characterised and compared in relation to flexural and compressive strength, microstructure, abrasive strength and hygroscopic behaviour. The results demonstrate that improvements in mechanical strength are dependent on the type of alginate used and the composition of the soil. The greatest increase in compressive strength is achieved using an alginate sourced from the Laminaria Hyperborea seaweed and offers a value more than double that of the equivalent control specimen. Increases in the alginate dosage do not necessarily lead to an increase in strength suggesting that there is an optimum concentration at which strength improvement is most effective.

“…Regarding the specific use of alginate, the most detailed study conducted to date is that by Galán-Marín et al [34] and Rivera-Gómez et al [35]. This involved the development of a composite clay brick product which incorporates an alginate polymer and natural fibres as reinforcing elements.…”

The construction industry has been at the forefront of scrutiny regarding the inefficient consumption of natural resources and energy intensive processes involved in the manufacture of materials. There is therefore a growing incentive to develop new building technologies which have a low environmental impact and can contribute positively to sustainable design strategies. The ambition of this research is to develop composite materials for building applications using biopolymers obtained from macro-algae. Macro-algae, or seaweed as it is more commonly known, is a renewable and abundant resource which contains various useful constituents which may be suitable for the development of new materials. This includes the biopolymer, alginate, which is the main structural polysaccharide of brown seaweeds. This study focusses specifically on the manufacture of unfired clay bricks which incorporate alginate as a binding agent in an effort to improve their strength. It is anticipated that these bricks could be utilised as an internal walling system, offering a low embodied energy alternative to other masonry systems such as fired brick and concrete. This study discusses the use of four different alginate products sourced from Scottish seaweeds which were used to produce small-scale unfired bricks. Properties such as the mechanical strength and shrinkage of the specimens have been investigated. Results have demonstrated that two of the alginate products improved both the compressive and flexural strength of the bricks but that the magnitude of the strength increase was dependent on the type of alginate used.
