“…The literature also suggests that concrete durability can be improved by incorporating mineral additives like slag [6], fly ash [7], and silica fume [8]. Furthermore, concrete durability can be enhanced by partially replacing aggregate with rubber [9][10][11][12], employing polymer binders [13,14], modifying [15][16][17] or impregnating concrete with polymers [18,19], using 2 of 12 polycarbonate superplasticizers [20,21], employing biomimetic polymer additives [22], and utilizing polymer fibers and biofibers [23,24].…”

The study explores the hypothesis that crystalline hydrophilic additives (CA) can enhance concrete’s resistance to freeze/thaw cycles, crucial for assessing building durability. Employing EU standards, the research evaluates concrete resistance through standardized European freeze/thaw procedures. Monitoring concrete slabs exposed to freezing in the presence of deionized water and in the presence of 3% sodium chloride solution, the study measures surface damage and relative dynamic modulus of elasticity. Additionally, it assesses internal damage through monitoring of relative dynamic modulus of elasticity on cubes and prisms submerged in water and exposed to freezing/thawing. The pore spacing factor measured here aids in predicting concrete behavior in freeze/thaw conditions. Results suggest that the standard air-entraining agent offers effective protection against surface and internal damage due to freeze/thaw cycles. However, the CA displays potential in enhancing resistance to freeze/thaw cycles, primarily in reducing internal damage at a 1% cement weight dosage. Notably, a 3% replacement of cement with CA adversely affects concrete resistance, leading to increased surface and internal damage. The findings contribute to understanding materials that can bolster concrete durability against freeze–thaw cycles, crucial for ensuring the longevity of buildings and infrastructure.

“…Mineral additives are finer than cement, making the cement matrix denser, which likely increases the proportion of smaller and less harmful pores while decreasing the proportion of larger and more harmful ones. Additionally, concrete resistance can also be enhanced by partially substituting aggregate with rubber [15][16][17][18], using polymer binders [19,20], modifying [21][22][23] or impregnating concrete with polymers [24,25], employing polycarbonate superplasticizers [26,27], using biomimetic polymer additives [28], and utilizing polymer fibres [29].…”

The causes of cracks in concrete are varied, and regardless of their origin, these cracks invariably have a detrimental impact on the durability of concrete structures and escalate their maintenance costs. This paper presents a comprehensive review of current knowledge regarding the methods of self-healing in concrete, ranging from autogenic and improved autogenic self-healing to the autonomous self-healing of concrete. Particular emphasis is placed on the methods of autonomous concrete self-healing: the bacterial healing method, the crystalline hydrophilic additives healing method, and the capsule-based self-healing method. The hypothesis is that applying these self-healing methods could potentially prevent damages or cracks in concrete caused by freeze–thaw cycles, thereby extending the lifespan of concrete structures. The mechanism of action and current achievements in the field are provided for each method.

This study aims to overview the current state of concrete-polymer composite (CPC) applications and proposes ways to develop and generalize the use of CPC in practical applications. According to the literature, polymer-modified concrete (PMC) is mainly formulated using SBR or epoxy-based latex and used for repair and overlays. Polymer concrete (PC) uses unsaturated polyester resin as a polymer binder and is mainly used for precast products. Polymer-impregnated concrete (PIC) research was actively conducted in the 1970s and 1980s, but currently, it is not easy to find except for a few applied studies. This study also presents the challenges and suggestions for developing and generaling CPC use in real-world practice.
