“…The cement-based carbon fiber material is a composite material prepared by doping carbon fiber material in cement-based composite material, it has the advantages of high crack resistance, corrosion resistance, antistatic, wear resistance, and lightweight. The improvement of carbon fiber materials on cement-based composites mainly comes from its excellent mechanical properties and the use of the synergistic effect of the two materials to improve their overall mechanical properties [ 6 , 7 ].…”

In order to solve the problem of drying shrinkage of cement-based carbon fiber materials in the early stage of hardening, the author proposes the application of cement-based carbon fiber materials in the construction of building durability. The author uses a self-designed fast ring test method to test and study the drying shrinkage performance of cement-based carbon fiber materials in the early stage of hardening. The results showed that the addition of MP-I and MP-II fibers, which can significantly reduce shrinkage cracking in plastic concrete, has little effect on preventing the shrinkage and cracking of concrete in the early stage of hardening. Mixed with a certain amount of steel fiber, carbon fiber, MH-I, and MPH-I hardened anticrack fiber, all have a better effect on preventing early water loss and drying shrinkage of hardening. The MH-I and MPH-I hardening anticracking fibers have an economical and feasible dosage, and the early water loss shrinkage and crack reduction rates of concrete hardening are 71.2% and 79.0%, respectively. MH-I fibers have no anticracking effect in the plastic stage and are only suitable for shrinkage and crack prevention of concrete in the early stage of hardening, while MPH-I hardened anticrack fibers have a 100% crack-reducing effect in the plastic stage, it is an engineering fiber material that can simultaneously prevent the plasticity and early hardening of concrete from shrinkage and cracking. The application of MPH-I hardened anticrack fiber is of great significance to improve the quality of structural engineering.

“…Additional research in the future development plan of what has already been carried out is seen in the study of the long-term properties of the resulting environmentally friendly concrete based on sunflower seed husks. In particular, large-scale studies of the structure and properties of concrete subjected to alternating cycles of freezing and thawing will be carried out, as well as water resistance and other properties that will characterize the special operating conditions of new environmentally friendly concrete based on sunflower seed husk ash [35,53,[76][77][78].…”

The limitation of the application of non-renewable materials is one of the solutions to the problem of the sustainable evolution of civilization in the 21st century. Using additional binders in concrete obtained from plant waste will be economically and environmentally beneficial and will also allow us to move closer to achieving sustainable development goals. This study searches for rational composition components and a methodological approach regarding the technological characteristics to get the highest quality elements and prime concrete properties on the basis of sunflower seed husk ash (SSHA). Experimental concrete specimens were manufactured with partial Portland cement substitution with SSHA amounts ranging from 2% to 16% by weight in increments of 2%. This study focuses on investigating the density and workability of the concrete mixture, along with the compressive strength, concrete density, and water absorption. This article used granulometric, microscopic, and X-ray phase analysis methods. Including SSHA in all considered ranges reduces the slump in concrete mixtures. The optimal SSHA content in concrete is up to 12%. An 8% SSHA content has been found to deliver the most favorable mechanical characteristics of the concrete studied. The compressive strength of the investigated concrete has increased by 14.89%, and water absorption has decreased by 15.78%. Doi: 10.28991/CEJ-2024-010-05-08 Full Text: PDF

The article presents the results of preliminary experiments necessary for the foundation of an experimental method that ensures the design and manufacturing technology for a category of composite materials with a mud matrix and agricultural waste insertion. The resources and physico-chemical properties of the mud matrix as well as the resources and physical properties of potential agricultural waste constituents of the insertion in the composite material are presented. The technological variant for the manufacture of the finished product is also presented, consisting of a compression system of the composite mixture in a paste state until solidification with moisture removal (dehydration). From a large number of parameters characterizing the experimental system, few have been varied (insertion concentration in the material, height of the raw material column in the press, raw material density, pressing force), while the quality parameters of the process have only been considered for the capacity of dehydration and material densification. The statistical analysis of the results shows that for the capacity of dehydration and densification, the main input parameters that influence are the initial moisture and initial volume of raw material. Results are obtained that allow the development of a mathematical model for the technological process of manufacturing the composite material. The purpose of the research described in this article is to determine the feasibility and feasibility conditions of the material in its possible variations. This means identifying the insertion concentration and moisture intervals of the material before extrusion, possible. The upper and lower limits of these parameters are sought, so that the material exiting the die does not immediately, or over time, disintegrate, and at the same time, the extrusion process is possible with a reasonable energy consumption.
