High-Strength Concretes Based on Comprehensive Nano-additives and Local Fine Sands

High-strength concrete composites based on nanostructured additives and small aggregates from local deposits Obtaining is an urgent task. The I/C reducing possibility by the mixing water surface tension values reduction using a comprehensive nanomodifier is established. It is shown that combined use of silicon acid sol gel nanoparticles and Frem Giper S-TB hyperplasticizer leads to the water surface tension decrease to 31.4 mN/m. It has been experimentally established that when using comprehensive nano-additives in fine-grained concrete based on a fine aggregate from the deposit in the Chechen Republic and with the concrete mixture mobility of P1, the strength of the obtained samples was 61.17 MPa. When using this comprehensive nanoadditive in fine-grained concrete based on a monofractive standard aggregate with the mobility of P1, high-strength composites with a strength of more than 70 MPa were obtained. High-strength fine-grained concretes with low deformations based on local sands with a low coarseness modulus were obtained with the combined use of silicon acid sol gel nanoparticles and Frem Giper S-TB hyperplasticizer at a standard cement consumption. X-ray phase studies show a significant decrease in the reflection of peaks belonging to portlandite Ca(OH)₂ when using a comprehensive additive. At the same time, the intensity of low-base calcium hydrosilicates peaks increases, which leads to a higher binding capacity. The obtained results make it possible to control early structuring of fine-grained concretes by impact the surface tension of aqueous surfactant solutions in cement concretes measured value.
