| One of the assumptions of sustainable development in construction is the use of low-processed materials. A material with a low level of embodied energy is clay. It is mainly used in fired form as building ceramics, but alternatively it can be used in raw form, e.g. in the form of plasters or unfired bricks. Clay can be modified with ingredients of plant origin, e.g. hemp shives. Porous plant fillers are used, among others, to improve the thermal insulation parameters of clay-based wall materials. The disadvantage of raw clay-based materials is their lack of water resistance. This parameter can be improved by using admixtures/ additives with hydraulic, hydrophobic properties or those ensuring chemical bonding of clay. In this work, a composite based on clay and hemp shives with a fine fraction was developed for use in walls, e.g. in the form of blocks and a rammed monolith. The density, thermal conductivity, water resistance and capillary rise of three mixtures were examined. A polysaccharide-based polymers (xanthan gum and guar gum) were used as an admixture to improve water resistance. The addition of xanthan gum in the amount of 1% reduced the composite's ability to capillary water uptake by 46% compared to the unmodified composite. Guar gum turned out to be an ineffective admixture as it deteriorated the properties of the clay composite. In the case of this admixture, in further studies, increasing the water content should be considered to improve the viscosity of the mixture, because it was noticeably too dry |
