“…The mix proportion of vegetation porous concrete needs to consider factors such as the selection and proportion of coarse and fine aggregates, the type and amount of cementitious materials, and the type of plants and their growing environment. The goal is to achieve the target porosity and pore size distribution that can support plant growth and root development [60,61]. The water-cement ratio and paste-aggregate ratio are significant parameters, with the former ranging between 0.25 and 0.35, and the latter ideally adjusted between 0.13 and 0.20.…”

Vegetation porous concrete is a novel material that integrates concrete technology with plant growth, offering excellent engineering applicability and environmental friendliness. This material is mainly utilized in eco-engineering projects such as riverbank protection, architectural greening, and slope protection along roads. This paper systematically reviews the current research progress of vegetation porous concrete by collecting and analyzing the relevant literature from both domestic and international sources. It covers several aspects including the material components of vegetation porous concrete, such as aggregates, cementitious materials, chemical admixtures, and plant species, as well as aspects like mix design, workability, porosity, pH value, mechanical strength, and vegetative performance. Furthermore, the application of vegetation porous concrete in riverbank protection, slope protection along highways, and urban architecture is discussed, along with a prospective outlook on future research directions for vegetation porous concrete.

“…Ten szczególny rodzaj betonu jest bardzo przepuszczalny, z porowatością sięgającą nawet 35%, co umożliwia absorpcję i odprowadzenie wody deszczowej oraz ułatwia jej naturalny przepływ w ziemi w sposób zrównoważony (19,20). Kruszywa pochodzące z recyklingu, kruszywa z żużla, a ostatnio także z muszli morskich, były przedmiotem szeroko zakrojonych badań w celu określenia ich potencjału jako substytutów naturalnych kruszyw w betonie wodoprzepuszczalnym (21)(22)(23)(24). Jeśli chodzi o muszle, Nguyen i in.…”

“…Recycled aggregates, slag aggregates, and, most recently, seashells have all been the subject of extensive research on their potential use as a substitute for natural aggregates in pervious concrete (21)(22)(23)(24). Regarding seashells, Nguyen et al (25) have examined the durability of pervious concrete based on the crushed seashells, where freeze-thaw resistance, clogging, and leaching tests were carried out.…”

Waste recovery is now a favourable solution for technical and economic reasons. The purpose of this study is the valuation of marine co-products – seashells, whose goal is to produce an eco-material that responds to the environmental problem. The experimental study focuses on the idea of replacing natural aggregates with recycled shell aggregates and studying their influence on the properties of pervious concrete. For this purpose, six concrete mixtures were prepared, where three of them were based on natural crushed limestone aggregates with 20% of porosity but had different dosages of cement 250, 300, and 350 kg/m3. The other three concretes have identical compositions, except that crushed shell aggregates substitute the natural aggregates. The obtained results are showing that the use of crushed shells considerably influences the properties of the studied concretes. In the fresh state, all concretes present high slump values and low density. Using shell aggregates improves the mechanical resistance, especially the tensile strength, by bending for the hardened state. Despite their shapes, the shell aggregates used in this study do not affect the concrete porosity, and consequently, draining concretes with good permeability have been obtained.

A standardized preparation process is proposed in this study for achieving optimal strength and vegetative properties in vegetated concrete, using Yunnan red soil as a growth substrate for plants. The porosity of vegetated concrete is a crucial factor influencing plant growth, while compressive strength is a significant mechanical property. To assess the strength and porosity of vegetated concrete, different design porosities (22%, 24%, 26%, 28%) and cement-to-aggregate ratios (4, 5, 6, 7) were utilized in the preparation of vegetated concrete samples. The shell-making and static-pressure-molding methods were optimized for specimen preparation. Analyzing the stress–strain full curve characteristics of vegetation-type concrete under different influencing factors, an in-depth investigation into its failure mechanism was conducted. It was determined that the design porosity and cement content significantly impact the concrete’s performance, particularly in terms of 30-day compressive strength and effective porosity. Furthermore, an increase in the fly ash ratio led to an increase in porosity and a decrease in compressive strength, providing a certain guidance for optimizing concrete performance. Comparative analysis through vegetation experiments revealed that black rye grass exhibited favorable growth adaptability compared to other grass species.
