Abstract

The impact of modifying hemp shives with water glass on selected properties of hemp-cement-limecomposite. The influence of the addition and modification of hemp shives with water glass on selected propertiesof the hemp-cement-limestone composite was investigated. Nine variants of composites were produced, differingin the volume content of hemp husks: 0%, 15%, 25%, 35% and 50%, modified or unmodified with water glass.For the produced composites, it was tested: density, compressive strength, MOR (bending strength), MOE(modulus of elasticity), thickness swelling and water absorption. Based on the conducted research, it was foundthat the increase in the addition of hemp shives results in a decrease in strength parameters and deterioration of thewater resistance of hemp-cement-lime composites. In turn, the modification of hemp shives with water glassimproves both the strength and physical properties (limited swelling in thickness and water absorption) of hempcement-lime composites compared to analogous composites based on unmodified hemp shives. The higheststrength parameters and the best resistance to water are demonstrated by a hemp-cement-limestone compositecontaining a 15% volume share of hemp shives modified with a 5% addition of water glass.
