Effect of Micro crystalline Cellulose on the Pervious Concrete Properties
Published in P. C. Thomas, Vishal John Mathai, Geevarghese Titus, Emerging Technologies for Sustainability, 2020
Sustainable engineering and construction practices are getting considerable attention in the construction industry and in the engineering profession due to concern about environmental sustainability. Stormwater management system plays an important role in human activities because fresh water is available to most of the people through storm water management system. Pervious concrete has been found to be a better stormwater management tool due to its high porosity, it is effective in managing runoff from pavements (Ikiensinma Gogo-Abite et al. 2014). The addition of reinforcing elements and fibers into pervious concrete showed an improvement in mechanical properties such as tensile and flexural strength increased (Rangelov etal. 2010).

Pervious concrete (PC) (Chandrappa and Biligiri, 2016) has been used as a means for reducing storm water runoff. The basic principle of operation of a PC layer is the quick transmission of storm water through an interconnected macro-pore internal structure. This structure is created by selecting appropriate coarse aggregate gradation and cementing materials. The gap graded material is created by single sized coarse aggregates with an optimal amount of cement to coat and bind the aggregates together. A minimum porosity of 15% and a typical range of 15–25% are specified. The water to cement ratio (w/c) is selected at 0.2–0.4, generally lower than that of conventional concrete. The volume of aggregate ranges from 50–65% with an aggregate to cement ratio of 4:1 to 6:1. The size of aggregates ranges from 19–9.5 mm with smaller aggregates (9.5–2.36 mm) being used occasionally. The physical properties of aggregates must meet the same specifications as those used in ordinary PCC. Generally, PC with granitic aggregates have been found to be more resistant to freeze thaw (F/T) damage compared to those with limestone or river gravel. The relatively thin cement paste in PC allows easier ingress of water into aggregates and hence the properties of the aggregates are very important for the development of appropriate resistance against F/T damage.

Permeable or pervious concrete allows water to seep into the ground to mix with groundwater or feed into stormwater drainage.14 With no sand but a highly adhesive paste to bind larger aggregates together, the water can flow through the porous material at the rate of 200 L/m²/min. It has a lower density and hence compressive strength but can still be produced for specific applications, such as pavements.

Another major concern for sustainable development is the increased stress on the water resources, especially groundwater. Developing countries like India even with abundance of running water depend largely on groundwater for all the major needs. Drinking water, irrigation and industrial manufacturing are some purposes for which groundwater are used. It has been reported recently that per capita groundwater availability in India has reduced by 70% over the last 50 years [21]. Pervious concrete is sought as a remedial measure to replenish groundwater levels. Pervious concrete is environmentally friendly material with no or hardly any fine aggregate and is used as pavement material which allows underground water to pass through it. Pervious concrete offers many advantages such as good drainage, higher noise absorption, conservation of natural aggregates and fixate heavy metals (Zn, Pb, Cu, and Cd) [22], which can lead to ground water contamination. Due to this, pervious concrete has been considered as environment-friendly material by EPA of the United States [23]. However, due to the lower strength of pervious concrete, its application has been limited to parking lots, sidewalks, parks, and low traffic volume roads [18, 19].

Pervious concrete is a composite material comprising of cement, coarse aggregate and water. It is highly porous and so, is an environment-friendly material that is in great demand in Europe, Japan and North America for the last four decades (Aamer Rafique Bhutta et al. 2013). Pervious concrete is used in many applications like parking lots where there is a need for draining and permeating water-reducing surface runoff and thereby improve the environmental performance of the existing site such as maintain the water quality, reduce flooding around the site, increase base flow and reservation of parking areas for the property owner. It is also beneficial as it helps maintain a quiet environment by absorbing the noise of vehicles and also prevent flash of surface and does not glisten at night improving the comfort and safety of drivers. Moreover, the pores of pervious concrete can cumulate heat, adjusting the humidity and temperature of the earth’s surface (Yang and Jiang 2003).

Pervious concrete was made an eco-friendly material in Japan in 1982 (Bhutta et al., 2012). This type of concrete has a pervious structure and interconnected cavities (Kim et al., 2017). Therefore, it has many benefits, such as sound and temperature insulation, ability to drain urban runoff and manage floods, recharge groundwater, and improve runoff and wastewater quality. One of the most common benefits of pervious concrete is using it in parking lots and sidewalks in order to manage urban runoff and flood. Due to abundant voids in pervious concrete, the resistance is far less than in other types of concrete. Therefore, many studies have been conducted to improve the structural properties of this material. Many early studies attempted to investigate the structural behaviour of pervious concrete by finding the appropriate amount of cement, the most optimal water to cement ratio (W/C), and/or comparison of changes in the amount of permeability and resistance by adding fine aggregates (Chindaprasirt et al., 2008, 2009; Haselbach et al., 2006). Results showed that suitable W/C ratio is very important for the resistance of pervious concrete. Also, adding a limited amount of fine aggregates causes a significant increase in the compressive strength and reduce permeability (Ćosić et al., 2015).
