| Title of the article | Study of operational properties of self-compacting sand concrete |
| Abstract. | For the successful implementation of sand self compacting concrete in construction, they should not concede on technical performance self-compacting concrete with large aggregate. The use of sand concrete not only increases the economic efficiency of construction, but also provides other advantages: simplified technological scheme of preparation of the concrete mixture, since it eliminates the need for warehouses and the sorting compartments for receiving, processing and storing of rubble, reduced the demand for electricity and labor. Therefore, obtaining self-compacting concrete using local raw materials, particularly sand as the sole filler has, for many regions of Russia is of great importance. The article shows that the use of the fractional composition of the sand allows you to reduce this figure to 0,67, and the use of SHVO allows obtaining self-compacting concrete W/C ratio of 0,62 and class mobility SF2. The results of the study operational characteristics of self-compacting sand concrete of classes B30-В40 show that the use of graded sand with the addition of SHVO and MK not only improves strength, but also to reduce the shrinkage strain of more than 15 %. The modulus of elasticity of the developed compositions of self-compacting sand concrete is comparable to the modular concrete with large aggregate, which allows to recommend them as a structural material for load-bearing structures without restrictions. |
