“…The use of engineering cementitious composites (ECC)a developed class of dispersion-reinforced materials based on Portland cementmakes it possible to increase the load-bearing capacity, stability under various static and dynamic influences, and the durability of building structures due to the controlled cracking process. However, ECC uses a significant amount of cementitious materials, often up to 70%, which leads to significant shrinkage deformations, limiting dimensional stability and increasing the cost of the material [8,9]. Supplementary cementitious materials, including ultra-dispersed mineral additives, are used to improve the quality of concrete [10,11].…”

The development of the construction industry has led to increased requirements for the operational properties of building materials in general and concrete in particular. Although concrete is designed primarily to withstand structural loads, it must also resist environmental influences to increase its durability. This article presents the results of the influence of the components of protective coatings on the hydro-physical properties of concrete. The edge wetting angle in concrete with a protective coating ranges from 95 to 101 degrees, which is about twice that of uncoated concrete. The mass of concrete under the influence of hygroscopic moisture increases, and after 30 days of exposure, it is 1.1–1.6 wt. % compared to 5.7–5.8 wt. % for control samples. The minimum increase (1.1–1.2 wt. %) is achieved when using coatings with the largest amount of heat-resistant varnish KO-08. The water absorption of the developed coating compositions decreases after 30 days of being in water from 5.2 to 1.6–2.2 wt. % for C20/25 concrete. Low temperatures negatively affect the hydrophysical properties of protective coatings, but only slightly. It has been found that water absorption increases by approximately 20 %.

“…In the past decades, for the sake of improvement of those disadvantages, many scholars have adopted different modification methods to cement-based materials. Some researchers found that the shrinkage properties of cement-based materials are significantly improved after the addition of appropriate fibers, such as steel fiber (SF) (Al-musawi et al 2019, Roberti et al 2020 , polypropylene (PP) fiber (Marushchak et al 2022, Ma et al 2022, basalt fiber (BF) (Punurai et al 2018, Zheng et al 2019. Some characters (Saje et al 2013, Ma et al 2017, George and Abin Thomas 2020 of fiber, like length, length-diameter ratio and the dosage of fiber, have great influence on the improvement of shrinkage.…”

In order to study the shrinkage properties of modified repairing mortar, an orthogonal experiment with four factors and three levels were proceeded. Nine specimens with four factors, i.e., silica powder, sodium silicate, basalt fiber and a U-type expansive agent, were used to measure the length change ratio. The results show that the shrinkage value of modified repairing mortars have been greatly reduced. Compared with the control specimen without any additives, the shrinkage value of the modified repairing mortar with the silica powder of 3 %, the sodium silicate of 1.0 %, the basalt fiber of 0.2 % and the U-type expansive agent of 10 % at 60d drops by 42.5%. Based on experimental results, the shrinkage prediction model of modified repairing mortar has been established. The model can be used to predict the shrinkage value of the modified repairing mortar with similar compositions.
