To date, composite materials, such as polymer concrete, have found wide application in various industries due to their unique properties combining high strength, resistance aggressive media and durability. Improving the performance characteristics of concrete is an important task aimed at expanding areas its application. One promising methods increasing strength this material use fillers. In paper, effect fillers, based on carbon basalt fibres, mechanical was investigated. The made following components: rubble stone, sand, quartz flour polyester resin. During experimental work, amount fibres mixture varied from 0 6%. Bending compressive tests showed that addition increased these properties. highest bending strengths were achieved when fibre contents up 1.5%, while provided case around 2%. These results confirmed had a higher efficiency strengthening compared fibres. This could be explained by fact tensile modulus elasticity, which allowed them better redistribute loads within material. length for fibre, gave maximum increase properties, 10–15 mm. For reached 20 mm 10 Increasing content above 2% 1.5% did not give further conclusion, it stated fillers offered significant advantages opening opportunities more demanding conditions wider range industrial applications.

One of the most important areas construction industry is road infrastructure. It plays a crucial role in economy various countries. Today’s roads must withstand long-term temperature and load differences, but some infrastructure cannot survive these tests, after one severe winter, there may be asphalt cracks holes that need to repaired. This problem requires new applications more resistant materials. Geopolymers are potential candidates. class material as building for has frost salt. The aim study herein demonstrate mechanical physical properties composite geopolymer made from fly ash, coal shale, nanosilica, carbon fiber application research experiments will serve determine whether geopolymers suitable replacing traditional concrete processes. following methods were applied: SEM, XRF, XRD, compressive strength testing, abrasion, investigation freeze–thaw resistance climatic chamber. results confirm possibility applying compositions infrastructure, including sufficient such ca. 38 MPa resistance, shown by mass loss about 1.7%, well abrasion 4%.

The addition of macro fibers to concrete pavements has been used improve the cracking pavement, reduce slab thickness and contribute increasing joint spacing. A laboratory test was carried out in study analyze impact fiber reinforced (FRC) on plain cement (PCC) roller compacted (RCC), determining flexural strength by performing ASTM-1609 tests compressive ASTM C-39 tests. Two synthetic types selected with different geometries dosages (0.25% 0.5% volume) were tested for both RCC PCC. To examine effect contents property, statistical testing done using strength-test data. result showed that not affected fibers. As content increased, residual (F600 F150) specimen toughness (T150) increased each type. contrary, specimens higher lower every case. Fiber properties including length shape more, than It is notable PCC same condition very similar, even though mix design strengths are different. In this paper, data results discussed, factors affecting limitations methods suggested.

When steel fiber and PVA produced in China made Japan are prepared according to the appropriate proportions, mechanical properties of hybrid fiber-reinforced cementitious composites (HFRCC) better, which is beneficial cost control has wide application prospects. The effects volume content fibers substitution rate on tensile strength, compressive flexural strength HFRCC were analyzed using factor optimization method principal component analysis (PCA). Through HFRCC, a mathematical model for comprehensive performance evaluation was established, multi-objective carried out. results show that compared with matrix, concrete increase significantly when 0.2–0.4% domestically or 50–100%. maximum reduction 88.25%, index can reach optimum; weights each obtained through statistics. Combined variable correlation analysis, these indicators should be noted optimizing HFRCC. research provide basis preparation
