“…However, while the water permeability was increased, the mechanical properties would be decreased. The results of Ariffin N. F. et al showed that with an increase in cementitious materials, the porosity and water permeability of PPC decreased, and the compressive strength increased [13].…”

Pervious planting concrete (PPC) is in line with the concept of ecological environmental protection. However, due to its own porous structure, it is difficult to obtain excellent mechanical properties and water permeability at the same time, which hinders its promotion and application. In this paper, natural gravel (NG), ordinary Portland cement (OPC), polyvinyl alcohol latex powder (PVAP) and polycarboxylate superplasticizer (PS) were used to prepare the PPC, and its mechanical properties and water permeability were studied. Three kinds of plants were planted in the PPC and their planting properties were studied. At the same time, the effect of Bacillus on the planting properties was studied. The results show that when the water–binder ratio (W/B) was 0.28 and the PVAP content was 0.8%, both the mechanical properties and water permeability of the PPC were optimal. The compressive strength and permeability coefficient were 14.2 MPa and 14.48 mm/s, respectively. The mechanical properties and water permeability of PPC prepared with 10~20 mm NG were better than those prepared with 5~10 mm NG. Among the three plants, the germination rate and growth of Elymus dahuricus Turcz (EDT) were the best. The incorporation of Bacillus can optimize its planting properties and promote the effective combination between plants and the PPC substrate.

“…However, to produce the epoxy resin-modified mortar hardeners are essential [ 17 , 18 , 19 ]. According to Ariffin et al [ 20 , 21 ], the inclusion of epoxy resin into the concretes imparts hardening properties when the alkaline substances are present. They developed the epoxy resin-modified mortars in the absence of any hardener.…”

This research investigated the application of epoxy resin polymer as a self-healing strategy for improving the mechanical and durability properties of cement-based mortar. The epoxy resin was added to the concrete mix at various levels (5, 10, 15, and 20% of cement weight), and the effectiveness of healing was evaluated by microstructural analysis, compressive strength, and non-destructive (ultrasonic pulse velocity) tests. Dry and wet-dry conditions were considered for curing, and for generating artificial cracks, specimens at different curing ages (1 and 6 months) were subjected to compressive testing (50 and 80% of specimen’s ultimate compressive strength). The results indicated that the mechanical properties in the specimen prepared by 10% epoxy resin and cured under wet-dry conditions was higher compared to other specimens. The degree of damage and healing efficiency index of this particular mix design were significantly affected by the healing duration and cracking age. An optimized artificial neural network (ANN) combined with a firefly algorithm was developed to estimate these indexes over the self-healing process. Overall, it was concluded that the epoxy resin polymer has high potential as a mechanical properties self-healing agent in cement-based mortar.

“…According to the study by Ariffin et al (2018), the addition of latex into the concrete matrix could signifi-cantly reduce the void ratio and increase the compressive strength of concrete. Ariffin et al (2018) showed that the use of 5% liquid latex polymer increased the concrete compressive strength up to 133.3%. Ion et al (2013) investigated whether the use of epoxy resin could result in a higher influence on the workability of the resulting concrete than the use of other types.…”

In this study, the mechanical performance and durability of latex-modified fiber-reinforced concrete were experimentally investigated. For these purposes, various types of tests were carried out: compressive, flexural, restrained drying shrinkage, water-tightness, and freeze and thaw tests. In total, 59 test specimens were manufactured and performed in this study. The latex weight fractions of 10, 15, and 20% and the fiber volume fractions of 0.2 and 0.3% were used as main test parameters. For each fiber volume fraction, amorphous and conventional steel fibers having the same amount were used together. Based on the test results, it was found that the use of 15% latex weight fraction could result in the very early development of concrete compressive strength at the seventh day; the ratio between the concrete compressive strengths at the seventh and 28th days was approximately 91%. The use of a 0.3% fiber volume fraction presented a higher concrete compressive strength at the seventh day than that of a 0.2% fiber volume fraction. In addition, the increase of the latex weight fraction up to 20% increased the flexural strength, and the increase of the fiber volume fraction up to 0.3% also increased the flexural strength. Moreover, using a high amount of latex could delay the crack development time while the final crack width was almost the same. The addition of latex and fibers into the concrete matrix also resulted in excellent resistances of permeability and freeze-thaw cycles.
