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.

“…For example, Specimen A has a higher k value by 50% when compared to polystyrene foam. Although all test specimens show higher thermal conductivity values in comparison with polystyrene foam, their values are still higher than that of other construction materials such as brick (4.81 W/(m.K)), 40 gypsum board (0.21 W/(m.K)), 41 and concrete board (0.35 W/(m.K)). 41 Also, they possess higher densities that reflects positively on other physical and mechanical properties, which are described in the next sections.…”

This paper introduces a novel composite from discarded pulled wool fibers as a sustainable alternative to commercial particleboard and medium density fiberboard (MDF). The investigation aims at designing composites with prominent properties in terms of thermal insulation, water absorption, flexural strength, and dynamic properties. Composites specimens are synthesized from recycled pulled wool fibers at three different densities namely 500, 800, and 1000 kg/m3, with and without fabric skin (core-only and sandwich specimens). Thermal conductivity test shows that core-only specimens with the lowest density (500 kg/m3) has lower thermal conductivity than particleboard and MDF by 30% and 50%, respectively. The sandwich specimens demonstrate 30%, 40%, and 70% less water absorption than MDF and particleboard. The results reveal high potential of pulled wool fibers to produce economic composites with appropriate thermal and physical properties that can be utilized for green buildings envelops. Dynamic tests show that the proposed composites exhibit higher damping values (70% higher in case of core-only specimens) as compared to particleboard and MDF. A main contribution of this work is presenting novel sustainable composites with high damping capacities, which promote their use as light weight structure components in critical applications such as aerospace panels subjected to high dynamic loading conditions.

The present research aims to identify the possibilities of rehabilitation of building facades in the centre of Chisinau, through the use of high-performance materials, use of high-performance technologies in execution, reduction of facade renovation costs, etc. In the process of organising the rehabilitation works of historical buildings of architectural value, we are dealing with the following: the value of the rehabilitation works of a historical building is very high, the duration of the rehabilitation is important, the attitude of the society is insufficient, the lack of strategies for the rehabilitation of buildings at the municipality level. In order to achieve this objective, we propose to research the following tasks: definition of the concept of rehabilitation of buildings in the Historic Centre of Chisinau; legislative, normative assurance of rehabilitation of historical heritage in the Republic of Moldova; analysis of the situation in Chisinau on the example of historical buildings with limestone finishes and examination by non-destructive methods of facades; solutions for rehabilitation of facades of historical buildings by comparing two types of technologies. In conclusion, emphasis will be placed on the choice of the most efficient method in terms of material, technology and cost.
