Master's Thesis from the year 2018 in the subject Engineering - Civil Engineering, grade: A, , course: Masters in Structural Engineering, language: English, abstract: Pervious concrete is a concrete which allows the water to pass through it. The pervious concrete contains cement, coarse aggregates, water and admixtures if needed. It has no sand in it which results in large amount of voids in the previous concrete. This sole property of having voids play a vital role in the functioning of the pervious concrete i.e; allowing water to pass through it. The pervious concrete has a disadvantage that it has less compressive strength when compare to normal concrete this backdrop in pervious concrete because pervious concrete is a no fines concrete it has no sand the sand which plays a vital role in the strength gain of the concrete hence we in our study has concentrated in improving the compressive strength but at the same time the permeability and void content should also not affected because permeability and void content are two most important properties of the pervious concrete which makes it the pervious concrete so basically we have also conducted study on the permeability and void content of the pervious concrete. In our study we have added different sizes of coarse aggregates such as 20 m, 12 mm, 12 +2 0 mm and we have added the sand percentages at 0 %, 0.25 %, 0.75 % and the compressive strength was checked on 7,14,28,56,90 days respectively and we have checked the permeability and void content at 28 days.

"This report provides technical information on pervious concrete's application, design methods, materials, properties, mixture proportioning, construction methods, testing, and inspection. The term 'pervious concrete' typically describes a near-zero-slump, open-graded material consisting of portland cement, coarse aggregate, little or no fine aggregate, admixtures, and water." [p. 1]

Pavements are the most ubiquitous of all man-made structures, and they have an enormous impact on environmental quality. They are responsible for hydrocarbon pollutants, excess runoff, groundwater decline and the resulting local water shortages, temperature increases in the urban "heat island," and for the ability of trees to extend their roots in

This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet's total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. - Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders - Considers performance in adverse environmental conditions. - Offers equal emphasis on the science behind the technology and its use in civil engineering.

Durability and service life design of concrete constructions have considerable socio-economic and environmental consequences, in which the permeability of concrete to aggressive intruders plays a vital role. Concrete Permeability and Durability Performance provides deep insight into the permeability of concrete, moving from theory to practice, and presents over 20 real cases, such as Tokyo’s Museum of Western Art, Port of Miami Tunnel and Hong Kong-Zhuhai-Macao sea-link, including field tests in the Antarctic and Atacama Desert. It stresses the importance of site testing for a realistic durability assessment and details the "Torrent Method" for non-destructive measurement of air-permeability. It also delivers answers for some vexing questions: Should the coefficient of permeability be expressed in m2 or m/s? How to get a "mean" pore radius of concrete from gas-permeability tests? Why should permeability preferably be measured on site? How can service life of reinforced concrete structures be predicted by site testing of gas-permeability and cover thickness? Practitioners will find stimulating examples on how to predict the coming service life of new structures and the remaining life of existing structures, based on site testing of air-permeability and cover thickness. Researchers will value theoretical principles, testing methods, as well as how test results reflect the influence of concrete mix composition and processing.
