• The physical and mechanical behavior of experimental mixtures with additions of cassava starch, carboxymethyl cellulose, and hydrated lime in a clay matrix is described. The added elements accounted for 3% of the weight of the mixes and the clay matrix for 97%. Mixing water was incorporated in different % according to the workability and molding of the mixes. Tests indicated the influence of additions on volumetric changes, particle detachment, and mechanical strength of the experimental mixtures. It was concluded that percentages ≥ 50% carboxymethylcellulose favored properties in mixtures. The opposite result was obtained with the addition of lime. Mixtures with additions of 25% cassava starch and 75% carboxymethylcellulose reported similar mechanical behavior and no particle detachment. [Display omitted] •Adding organic elements improves the mechanical strength of the clay matrix.•Carboxymethylcellulose prevents particle detachment in clay matrix mixtures.•Hydrated lime prevents drying shrinkage clay.•Cassava starch and carboxymethylcellulose improved the properties of the clay matrix.•Using organic elements to manufacture materials contributes to their biodegradation.
