Mechanical Properties of Fiber-Reinforced Concrete Using Composite Binders

Abstract: This paper investigates the creation of high-density impermeable concrete. The effect of the "cement, fly ash, and limestone" composite binders obtained by joint grinding with superplasticizer in the varioplanetary mill on the process of structure formation was studied. Compaction of structure on micro-and nanoscale levels was characterized by different techniques: X-ray diffraction, DTA-TGA, and electron microscopy. Results showed that the grinding of active mineral supplements allows crystallization centers … Show more

“…The study of autogenous shrinkage of cement paste is very important for a better understanding of that of mortar and concrete. Another limitation of the existing studies is that most of them are only about one type of supplementary material and the water-binder ratio of mixtures concerned in different studies always varies [12][13][14][15][16][17][18][19][20]. Therefore, it is hard to compare the effects of different supplementary materials on autogenous shrinkage based on the available results from the literature.…”

“…It was also found that, with the decrease in the diameter of the AC particles, the sorption capacity for petroleum products increased. The maximum values of the sorption capacity of the activated carbons with a particle size 0.5 mm was determined, which made up 2.0 g/g for petroleum, 4.0 g/g for I-20A oil, 1.5 g/g for kerosene and 0.7 g/g for petrol [ 92 ].…”

“…Development of new strain-hardening inorganic composite can be in mixture composition and in manufacturing technology. In study of mixture compositions the following results were obtained: the use of microfiber in the amount of 2% by volume or more [51][52][53][54][55]; the use of rheologically active mineral additives in cement matrices with a superplasticizer to ensure workability at low W/C ratio and at high microfiber amount [56,57]; the use of mineral additives that improve workability and setting time in alkali-activated slag matrices [58][59][60][61]; the use of quartz sand with a low fineness modulus as a fine aggregate to obtain a homogeneous matrix and ensure a dense and uniform contact of matrix with the microfiber surface [62][63][64][65][66][67][68]. Manufacturing technology takes into account: the sequence of addition of components into a mixture [69][70][71][72][73]; mixing modes [62,[74][75][76][77].…”
