“…3 Compressive behavior of concrete confined with low-cost natural fiber reinforced polymer (NFRP) has been established in article. 4 Results in Reference 5 shown that increasing angularity, aggregate size, and volume, and decreasing w/c ratio improve fracture toughness by 30% whereas changing paste, fly ash, and air void content negligibly influence fracture toughness. The high temperatures of fires affect the physical and chemical properties of the Discussion on this paper must be submitted within two months of the print publication.…”

Concrete is the most important material in civil engineering. Development of concrete strength could be determined by ratio of water and cement. However recent studies suggested that the concrete strength is influences also by other ingredients. Concrete with high performances is very complex material therefore the analyzing of the materials could be rather difficult and challenging task. The concrete compressive strength is a highly nonlinear function of age and ingredients. These ingredients include cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, and fine aggregate. In order to decrease the complexity the main goal of the study was to determine which variable are important and which variable are not important for the concrete strength analyzing. As the output variable compressive strength of the concrete with high performance was used. Since the concrete compressive strength is a highly nonlinear function in this article computational intelligence was used. Results suggested that the age has the highest impact on the compressive strength of the concrete with high performance.

“…A small difference in the values of temperature deformations of lightweight aggregate and cement stone is one of the factors increasing the frost resistance of such concretes. The accumulation of irreversible residual deformations, other things being equal, occurs here more slowly and, mainly, due to cracking in the mortar part of lightweight concrete with the retention of contacts between the filler and cement stone [13].…”

The features and mechanisms of the processes occurring during concrete centrifugation are considered. It was found that a significant difference in the centrifugal and centripetal forces acting on the outer, middle and inner layers of the cross-section leads to significant differences in the structure and characteristics of the element layers. The possibility of regulating the variatropia and controlling the concrete properties during centrifugal seal by regulating the prescription factors is considered. The forms of various aggregates’ interaction with cement stone and the mixture components’ separation features during centrifugation are analyzed. Based on the analysis data, it is proposed to use a combination of various types aggregates and densities in centrifuged concrete. The main types of fibers are identified and the analysis of the effectiveness of their use is carried out. On the basis of the performed analysis, the most promising way of increasing the efficiency of fiber-concrete centrifuged elements was determined, namely, the combination of two or more types of fibers. The most expedient combinations of the aggregates and fibers’ types have been identified, which makes it possible to guarantee the directional movement of the components of the concrete mixture during centrifugation. In terms of the aggregate, this is the use of a large aggregate with a high density and a fine aggregate with a lower density, and in terms of fibers, it is a combination of steel and non-metallic fibers.

“…Besides some studies available in the literature about the use of natural fibers in Fiber-Reinforced Polymer (FRP) systems [10] [11] [12] [13], also in combination with carbon fibers [14], the use of fibers and fabrics obtained by various plants appears to be particularly well suited as internal reinforcement for mortars in inorganic-matrix composite systems [15][16] [17] [18]. Specifically, the use of hydraulic lime mortar has proven to be more compatible than cement-based mortars in terms of chemical compatibility and resulting durability performance with natural fibers, such as jute [19], hemp [20] and sisal [21].…”

“…Building on the results already available in the literature, the preset paper focuses on the mechanical behavior of jute, which have been also used as internal reinforcement in crude earth bricks [25], JFRP [13] and concrete elements [26][27] [28]. Moreover recycled jute fibers have been used in the preparation of natural insulation materials [29] [30] and the burnt clay bricks reinforced with jute fibers and its thermal properties have been reported in [31].…”
