"This paper presents the results of a study on the effect of fully biodegradable modified starch in the form of LU-1400-2 dextrin(denoted d2) and two commercial plasticizers P1 and P2 on selected properties of cement mortars. The studied cement mortar wasenriched with 0.25%, 0.30%, 0.35%, and 0.40% d2 dextrin, relative to the weight of the cement. The tests carried out indicate that theaddition of dextrin to cement mortars results in an increase in strength (a 9% increase was observed with 0.25% dextrin) andliquefaction of the mixtures. However, commercial plasticizers were found to decrease compressive strength. Starch derivatives are atype of natural plasticizer that is more environmentally sustainable than other types. They are produced from renewable sources, suchas plants, and their production generates less waste and involves low greenhouse gas emissions. They are produced from renewablesources, such as plants, and their production generates less waste and involves low greenhouse gas emissions. Preliminary studiessuggest that dextrins have great potential as natural plasticizers. The increasing popularity of natural plasticizers in the chemical andconstruction industries is due to a growing interest in sustainability and concern about the harmful effects of traditional chemicalplasticizers."
