TL;DR: In this article, the physical and mechanical properties as well as the seawater purification characteristics of water-permeable concrete using recycled aggregate, granular artificial zeolite, silica fume and glass fiber were investigated and analyzed.
Abstract: This study investigated and analyzed the physical and mechanical properties as well as the seawater purification characteristics of water-permeable concrete using recycled aggregate, granular artificial zeolite, silica fume and glass fiber in order to present effective utilization of waste concrete aggregate and derive a method to improve the performance and seawater purification characteristics of water-permeable concrete. The strength test result showed that the strength increased as the mixing ratio of the recycled aggregate was increased. However, it demonstrated the characteristics of greater compressive strength and flexural strength than plain concrete by 50 and 75%, respectively. The result of measurement for the dissolved oxygen consumption amount as well as T-N (total nitrogen) and T-P (total phosphorous) after the water-permeable concrete was immersed in the artificial water channel indicated that as the target void ratio was greater, the seawater purification performance was more excellent. In addition, it was found that the mixing of the granular artificial zeolite is effective for seawater purification. Therefore, it was discovered that even though the aggregate was replaced with recycled aggregate when making water-permeable concrete for seawater purification, if an appropriate amount of admixture was mixed, the recycled aggregate was effective for the physical and mechanical properties as well as the seawater purification characteristics. It was thought that the appropriate mixing ratio of the recycled aggregate was approximately 50% when the target void ratio was set to 20%.

TL;DR: In this article, the authors imitate the bone self healing process by putting porous concrete internally in formed and detected by sensors, healing agent can be infused into the porous network so as to fill up voids and seal a crack or cracks in the concrete body.
Abstract: To repair concrete cracks in difficult or dangerous conditions such as underground structures or hazardous liquid containers, self healing mechanism is a promising alternative method. This research aims to imitate the bone self healing process by putting porous concrete internally in formed and detected by sensors, healing agent can be infused into the porous network so as to fill up voids and seal a crack or cracks in the concrete body. This idea was tested using cylindrical samples. A porous concrete core was placed in the center of the concrete cylinder. Uniaxial direct tensile load was applied to create cracks close to the notch of the sample. A healing action was performed by injecting healing agent manually. The results show that a macro-crack is sealed and strength of concrete is regained. Therefore, the concept is considered as to be feasible for self repair mechanism in concrete.

TL;DR: In this paper, the fundamental hydrologic behavior of pervious concrete pavement systems and basic design methodologies appropriate for a variety of sites and circumstances are described and discussed. And the limitations of these methodologies are discussed.
Abstract: A properly designed pervious concrete pavement system can reduce the environmental impact often associated with development. Pervious concrete pavement systems can also be used to improve the environmental performance of existing sites without compromising the business value of a property by replacing existing conventional pavements. The capability to simultaneously maintain water quality, reduce flooding, increase base flow, and preserve valuable parking areas for the property owner, especially in retrofit applications, are capabilities not easily obtained with other water quality or flood mitigation alternatives. Pervious concrete also provides a unique leadership opportunity for stewardship in context-sensitive construction and Low-Impact Development (LID). This document describes the fundamental hydrologic behavior of pervious concrete pavement systems and demonstrates basic design methodologies appropriate for a variety of sites and circumstances. This document also briefly discusses limitations of these methodologies.
