Construction of pervious concrete (PC) pavements is an exclusive and efficient measure for solving environmental problems while also contributing to sustainability. Pervious concrete enables rainwater to percolate into soil thus reducing the storm water runoff and assisting in ground water recharge. It is used for the construction of pedestrian pathways, parking lots, and in various other applications. During the research, the content of coarse aggregate grains in geopolymer binder was varied in order to investigate pervious concrete properties. It was established that pervious concrete with geopolymer binder containing fly ash meets requirements set in regulations, and that it can be used for sustainable pavement construction.

Pervious Concrete which is also called as Noamercement Concrete is a combination of cement, water and a particular size of coarse aggregate combines to form a porous structural material. The main application of pervious concrete in pavements is for storm water control which occurs mostly in urban areas where scarcity of land is high. Permeable Pavement allows surface runoff through it and hence stops the overflow which improves ground water recharge. In this paper investigation on compressive strength, flexural strength, water permeability, density and void ratio has carried at 0.33% water cement ratio(W/C) for cement aggregate ratio (C/A)0.25 to three set of coarse aggregate(CA)sizes without fine aggregate . Summarizing that 12.5 mm (passing) to 10 mm (retained) size of aggregates has shown good results than remaining sizes for compressive strength, permeability, density and void content.

Pervious concrete is a light weight concrete containing voids in the range of 14 to 31%. The usage of pervious concretes has been in- creased due to its merits on pollution control and environmental considerations. The pervious concretes are also used to reduce the storm water runoff and recharges the underground water table. Eventhough the pervious concrete has lot of merits, it also has consider- able demerits related to strength issues. In order to achieve the strength high cement content mixes may be incorporated which is not a viable solution. In this paper, geopolymer technology has been used to develop pervious concrete. Geopolymer pervious concrete is pro- duced using GGBS as raw material and sodium hydroxide and sodium silicate as activator solution. Five mixes have been developed with varying GGBS content of 450, 460, 470, 480 and 490 kg/m3. The cement to aggregate ratio is fixed at 1:3 for all the mixtures and the water cement ratio is kept constant at 0.3. The compressive strength revealed that strength of around 20 MPa was attained for all the mixtures and strength increases with respect to the increase in GGBS content. There was not significant changes in the permeability property since the aggregate cement ratio is maintained for all the mixtures.

Abstract Small water reservoirs play important role in rural areas. They used to be very popular, but most of them have been devastated in the last century. It is worth to restore them and to construct new ones. Very small reservoirs (ponds) can be constructed in economical and cost efficient way by individual farmers. In regard to damming below 1.0 m and to reservoirs situated outside protected areas, the permission for construction and the environmental impact assessment is not required. However, one should always keep in mind that even the smallest construction is the work of engineering and should be performed in accordance with the current standards. The increase of available water resources and improvement of water quality demand various measures including those aimed at reducing and limiting water runoff and pollutants transport from the river basins. One of the methods to improve the structure of water balance and the amount of water in rivers is the construction of a large number of small reservoirs, wetland reconstruction etc. Such reservoirs may be divided to: recreational, floristic and faunistic conservation sites, swimming pools, water quality protection (constructed wetlands) and infiltration reservoirs. Reservoirs can have many functions of the economic and natural character. If they are designed and constructed properly they can be a valuable element of the natural landscape in rural areas. Basic data for designing of small reservoirs serving mainly recreational (decorative) purposes and those used for water treatment and ground water recharge are given in the paper

A Site

Pervious concrete is a type of concrete with high porosity. It is used for concrete flatworks application that allows the water to pass through it, thereby reducing the runoff from a site and allowing ground water recharge. The high porosity is attained by highly interconnected voids content. Pervious concrete has water to cementicious material ratio of 0.36. The mixture is composed of cementicious materials, coarse aggregates and water with no fine aggregates. In this paper works porous concrete with fly ash as a blended material is tested for strength and permeability for assessing the adaptability of fly ash as a substitute material to cement. The percentage of fly ash is varied from 10% and 20%. Various tests like compressive strength, tensile strength and water permeability are done on the specimens and results are discussed.

Abstract Pervious concrete is a unique and effective material used to tackle important environmental problems, to maintain green, sustainable growth, and to reduce storm water runoff and pollutants. Clogging of pervious concrete is an important potential issue in serviceability, considered one of the primary limitations of pervious concrete systems. The sediment deposition pattern of pervious concrete was determined using three clogging materials: clay, sand, and clayey silty sand. The clogged specimens were cleaned by pressure washing, vacuuming, and a combined method. In total, ten clogging and cleaning cycles were carried out on each sample to evaluate the draining capacity of the pervious concrete. The clogging test was assessed by measuring the infiltration rate during clogging and after cleaning, for each cycle. The experiment results showed that a reduction in permeability due to different types of sedimentation material as well as recovery in permeability was achieved after applying various cleaning methods.

Potential Applications

Pervious concrete is one of the materials with potential applications in the construction industry because it can help reduce environmental problems caused by conventional concrete, improve storm water management, and provide a low-impact development alternative. Pervious concrete has numerous advantages, including assisting with water filtering and lowering pollutants. The ability to reduce storm water runoff is the most important feature that attracts the attention of pervious concrete. The objective of the present investigation is to evaluate the properties of pervious concrete and compare them with normal concrete. On the other hand, the requirement for aggregate to produce concrete is high, while natural resources are reduced. An attempt was made to use Black Marble Stone Waste Aggregate in concrete by replacing natural aggregate at a ratio of 0, 50, and 100%.To obtain the behavior of pervious concrete, compressive, shear and bearing strength are evaluated. A total of 54 specimens were casted and tested in this experimental work to study the behavior of concrete. To assess the shear and bearing strengths, a regression model was developed.
