ABSTRACT
Taking into account the multiple possibilities of using these wastes in the present paper is presented the capitalization of protein residues powder, obtained by their incineration, introduced as addition in cement concrete. The study of cement concretes obtained by using different types of wastes is an actual necessity because of the huge quantities of landfill wastes which pollute the environment. In the paper are presented the properties of cement concrete prepared with different types of organic wastes (hair, feather and wool). The wastes were used as addition in the concrete composition in a dosage of 10% from the cement quantity. Compressive strength and flexural strength were investigated and compared with that of control concrete without additions. Mechanical characteristics were generally under the values of control mix. The higher mechanical strengths were obtained for cement concrete prepared with hair and a combination of hair and wool. The statistical analysis such as Pareto chart for example was used on experimental data for determining the most influent parameter. By recovering and using of these materials in the cement concrete composition it can diminish the costs of concrete, even these concretes can be used only for non-structural elements.
