“…87,88 Compared to 3DPC mixtures, it is expected that the evaporation of pore water will be delayed and the severity of plastic shrinkage will be less as a result of the use of formwork and curing in conventional concretes. 89 Compared to conventional concrete, 3DPC mixtures are more exposed to environmental influences such as temperature, humidity and wind after extrusion as no formwork is used. This situation causes the increase of plastic shrinkage cracks in 3DPC mixtures and negatively affects the strength and durability properties of the printed concrete.…”

In this study, the strength and durability performance of 3D printing concrete mixtures (3DPC) were examined in terms of the materials used in their production and printing process parameters (interlayer interval time, printing speed, and nozzle shape). Due to the anisotropic nature of 3DPC, it was understood that the compressive strength depends on the loading direction. It was emphasized that it is necessary to control the shrinkage behavior of 3DPC mixtures due to the lack of formwork and the high dosage of binders. It was reported that the interlayer adhesion of 3DPC is highly dependent on the interlayer interval time and printing speed parameters. It was understood that nozzle shape and standoff distance affect the mechanical properties and surface roughness of 3DPC specimens, and this effect is more pronounced in mixtures with high static yield stress values.

“…Several techniques have been developed recently to protect concrete floors exposed to water [ 12 , 13 ]. These techniques can be classified into four categories: (1) rebar coated with epoxy resin (2) anticorrosion agent, (3) re-alkalizing concrete, and (4) concrete surface modification [ 14 ]. As a result of their limited applicability and lack of clarity about their results and expected service life, there is little acceptance of the first two techniques.…”

“…It has the advantages of easy access to raw materials and excellent mechanical properties, but it also exhibits the disadvantages of low tensile strength, high brittleness, and easy cracking. In the field of transportation engineering, the problem of durability in concrete structures has been the focus of attention due to the high brittleness and easy cracking of concrete [ 1 , 2 , 3 ]. In order to reduce the brittleness and cracking of concrete, a variety of toughening materials, such as fibers, polymers, and rubbers, have been used to prepare concrete.…”

Brittle fracture is a typical mechanical characteristic of high-strength self-compacting concrete, and the research on its toughening modification remains the highlight in the engineering field. To understand the effect of toughening materials (including polymer latex powders, rubber particles, and polyethylene fibers) on the mechanical behavior of C80 high-strength self-compacting concrete under static loading, the failure mode, mechanical strength, strain field, and crack opening displacement (COD) of prepared high-strength self-compacting concrete under compressive, splitting, and flexural loads were studied based on digital image technology (DIC). The corresponding mechanism is also discussed. The results show that the hybrid of polymer latex powders, rubber particles, and polyethylene fibers can increase the crack path and inhibit the development of macrocracks in concrete, thus turning the fracture behavior of concrete from brittle to ductile. The addition of toughening materials reduced the compressive and flexural strengths of high-strength self-compacting concrete, but it increased the splitting strength. DIC showed that the incorporation of toughening materials promoted the redistribution of strain and reduced the degree of strain concentration in high-strength self-compacting concrete. The evolution of COD in high-strength self-compacting concrete can be divided into two stages, including the linear growth stage and the plastic yield stage. The linear growth stage can be extended by incorporating toughening materials. The COD and energy absorption capacity of concrete were enhanced with the addition of toughening materials, and the best enhancement was observed with the hybrid of polymer latex powders, rubber particles, and polyethylene fibers. Overall, this research provides a reference for exploring effective technical measures to improve the toughness of high-strength self-compacting concrete.
