[Utilization of modified waste from the antibiotic industry for the production of construction materials].

Possible utilization of treated streptomycin fermentation broth modified with waste hydrochloric acid solution followed by lime neutralization was studied. Such a complex additive to concrete increased its strength by 36-41 per cent. With saving cement by 7 per cent the concrete strength increased by 22-29 per cent as compared to the control samples. Therefore, utilization of antibiotic industry waste in production of building material allowed not only to improve its quality but also to lower the environmental pollution.
