Improvement of rural settlements is an urgent task to create attractive living conditions, preserve cultural traditions, develop ethnic tourism and create a unique look for the villages and villages of the Don region. It is advisable to make small architectural forms of concrete, which is a versatile and durable material that allows any designer’s creative idea to be realized. The performed studies have established that it is rational to produce small architectural forms from fine-grained self-compacting mixtures with screenings of stone crushing of rocks of the Don region. The experiments have shown that in a fine-grained self-compacting mixture, the optimal dosage of ordinary limestone crushing screenings is 20%, and sandstone crushing screenings can reach 33%. This is explained by an increase in the liquefaction effect of the anionic superplasticizer due to its lower adsorption on fine particles of sandstone grains, which have a predominantly negative surface charge. The mobile production of small architectural forms from fine-grained self-compacting concretes with stone crushing screenings on the territory of crushing and sorting plants will allow organizing a promising business and creating new jobs for residents of rural settlements. |
