Concrete is a composite material that is widely used in the construction industry due to its excellent mechanical and physical properties. Despite these benefits, concrete possesses several disadvantages including negative environmental impacts and mechanical durability (e.g., shrinkage, frost attack, and corrosion). To date, upgrading of concrete's properties to overcome such drawbacks has been one of the most challenging, but attractive, research topics for many researchers in this research field. As one of the effective means to meet such demand, the use of natural zeolites in the production of concrete has been made preferably to acquire the excellent performance along with improvement in terms of structure, durability, and mechanical properties. This review was designed to provide a comprehensive insight into the construction-related applications of natural zeolite. To this end, we discussed the structural and fundamental properties of natural zeolites and their applications to concrete production as natural pozzolans, internal curing agents, and lightweight aggregates. Also, through critical analysis of various researches made previously, we aim to offer a better understanding on the effect of zeolites' addition upon the performance of concrete in terms of workability, strength, durability, and permeability. Additionally, we describe the present challenges and future perspectives in the use of natural zeolites for concrete production.

Pervious concrete pavements have good drainage capabilities; however, storm water runoff during extreme events can cause the pores clogging in permeable pavement. This study aims to preliminarily reveal the mechanism of sediment clogging in the pores of the pervious concrete pavement under storm water runoff. An innovative continuous permeability measurement system combined with the electrical conductivity measurement is developed. Laboratory simulation tests are conducted with this system to demonstrate the effects of four factors on the permeability reduction. The tests indicate that the pore clogging process generally includes three phases, i.e. quick clogging, temporary mitigation of clogging and progressive clogging. The clogging is more prone to occur in specimens with large porosity. Meanwhile, the variation of electrical conductivity of pervious concrete can accurately reflect the clogging process of pervious concrete. A rapid clogging model has been developed and validated.

Experimental Study on the Relationship between Permeability and Strength of Pervious Concrete

Drainage capacity of pervious concrete pavements will be greatly decreased once the pores become clogged. In this study, the mechanism of sediment clogging in the pores of the pervious concrete pavement under surface runoff is preliminarily revealed. Based on the modified permeability measurement system, a series of laboratory simulation tests are conducted to demonstrate the effects of porosity of pervious concrete, sediment size, depth of free surface flow, storm water runoff velocity on the permeability reduction due to clogging of the porous pavement. Within the scope of this study, the clogging is observed to more easily occur for specimens with large porosity, for well-graded sand as the clogging materials and large storm water depth. Horizontal runoffs has little influence on the final clogging ratio.

Sediment transport and pore clogging of a porous pavement under surface runoff

Having the advantages of high permeability and high strength, pervious concrete is suitable for improving ground-bearing capacity. In the Yellow River Delta, a pervious concrete pile (PCP) composite foundation has been constructed to reduce settlement of an expressway embankment. To study the working mechanism of PCPs, a numerical model was constructed based on the finite-difference method and Biot’s consolidation theory, which was validated by data from in situ tests. The excess pore-water pressure, pile–soil stress ratio, lateral displacement, and settlement of the PCP composite foundation under the loading of the road embankment were numerically calculated and compared with those of gravel pile and low-grade concrete pile composite foundations. Comparisons show that the dissipation of excess pore-water pressure in the PCP composite foundation was fastest, which implied that PCPs can significantly mitigate the development of excess pore-water pressure and thus enhance subsoil strength. Furtherm...
