| Title of the article | The modification of road-building materials based on run-of-crusher stone, treated by cement, by the introduction of natural sand and methylsiliconate potassium |
| Abstract. | When the economic activities are exercise of in the field of mining, there is a necessity of rational using of wastes and local raw materials. From the variety of non-metallic minerals the run-of-crusher building stone can be identified, which in rare cases, are used as a building material. In areas with a lack of inventory of durable rubble, using the local mineral materials, in particular run-of-crusher stone limestone, treated by cement, become one of the possibilities to reduce the construction cost, saving energy, resources and time. However, run-of-crusher stone treated by cement have a low rates of strength and freeze-thaw resistance and therefore, it is require the modification by different target additives, including organosilicon compounds. The influence of the natural sand in the composition of the treated run-of-crusher stone on physical and mechanical properties was determined. With the experimental design method according to the impact of consumption of cement, sand and methylsiliconate potassiumon physical and mechanical properties of the treated run-of-crusher stone were obtained. The optimal dosage of additives to produce materials with marks on the M40 strength, M60, M75 and frost resistance F15 were found. |
