A Review on Performance of Pervious Concrete Using Waste Materials
International Journal of Research in Engineering and Technology, 2015
Pervious concrete is one of the most promising sustainable material nowadays. Pervious concrete is the mixture of cement, smaller size coarse aggregate, water and admixture. As cement industry is one of the most polluted industry, so for reducing the pollution and cost of concrete cement may be fully or partially replaced by waste materials like fly ash, rice husk ash, waste rubber tire, furnace slag, silica fume, solid waste etc. This paper illustrates the performance of pervious concrete with these sustainable materials replacing or partially replacing cement & aggregate. It is observed from the study that compressive strength of pervious concrete is increasing by introducing fly ash, furnace slag, and rice husk ash, silica fume, and solid waste (glass powder, ceramic waste, bottom ash). Whereas compressive strength is decreasing by addition of rubberized materials. Permeability is increasing with furnace slag, ceramic waste but glass powder, silica fume has no effect on permeability. Though rubberized materials decreases the tensile strength and compressive strength of pervious concrete, it increases the abrasion resistance & freezing-thawing resistance. Partial addition of rice husk ash, furnace slag, silica fume, glass powder also enhance tensile strength of pervious concrete. All the above mentioned materials are environment friendly but solid waste, furnace slag and silica fume has the highest contribution to the strength and permeability of pervious concrete.

Utilization of Waste Products and By-Products in Concrete : The Key to a Sustainable Construction I
2013
In the 21st Century, we have been using the natural resources at a rate that cannot be sustained indefinitely. Exploiting these resources and extent of energy used in their consumptions, results degradation of our balanced ecological system in the form of pollutants, wastes generation, heat sink effects in the cities etc. Tremendous amount of waste materials and by-products like GGBS, waste glass etc. is generated from the industrial sector. These materials are difficult to dispose and cause serious environmental problems. Morever construction sector also contributes a lot to the emission of Greenhouse gases (GHG’s) besides consuming the nonrenewable natural resources. These environmental problems can be resolved by utilizing the industrial wastes and by-products to create beneficial construction materials. In addition use of these materials resolves various environmental issues such as GHG’s emission, construction wastes disposal etc. These materials also enhance the mechanical and...

This research presents laboratory studies on the properties of concrete that contains ternary blends of Portland cement, fly ash, and silica fume. Nine concrete mixtures were prepared with water to cement material ratio of 0.5. The concrete mixtures were designed to have the same degree of workability and percentage of air content. Tests were executed and measurements (i.e. compressive strength, tensile strength, dynamic elastic modulus and static young's modulus) were undertaken. The results indicated that concrete made of such materials (i.e. environmental friends) showed hardened properties since the combination of fly ash and silica fume is somehow synergistic. The research concluded that the replacement of 35% of cement quantity with 25% fly ash and 10% silica fume increased the compressive strength by 20% at 180 days. In addition, the results indicated that the use of ternary natural cement like materials systems in concrete showed a significant resistance to sulphate attack. Moreover; using such materials reduce environmental impacts by reducing the production of cement thus causing the reduction of greenhouse gases emissions, reduction of used energy in cement industry and disposing the natural cement like by-product.

Pervious concrete or high absorption concrete which derives its name from its permeable nature is a permeable pavement structure with primary function to manage storm water in order to prevent flood while serving as a concrete structure where strength is the most important factor. Fines are systematically removed to create a porous structure which allows water penetrate. In this research, pervious concrete was produced with no fines. The samples contained aggregates with different gradations marked AB (16mm – 19mm), BC (14mm – 19mm), CD (12.5mm – 19mm) and DE (4.75mm – 19mm) with fineness modulus of 3.21 were tested for compressive strength, density, infiltration rate and porosity. The results show that the optimum mix of pervious concrete was obtained using aggregate gradation DE (4.75mm – 19mm). Relationship between aggregate gradation, its compressive strength, density, infiltration rate and porosity were obtained. The 28-day average compressive strength of this pervious concrete...

The utilization of solid waste in useful product is becoming a great deal of worth for individuals, organizations, and countries themselves. The powder of waste glass and silica fumes are also considered major waste materials across the globe. In this paper, the physico-chemical, thermal, and morphological properties of both waste powders are investigated in order to determine their suitability for use as a partial replacement for cement in basic concrete. They are suitable for use in concrete due to their pozzolanic and other basic properties. Extensive testing, in terms of the compressive strength test, the slump test, and the flexural strength test, has been carried out to study the replacement of cement in the range of 5–15% by waste glass powder for curing ages of 7 and 28 days. The FTIR analyses of both materials are studied for determining the effect of characteristics of chemical bonding and intense bands with bending vibrations of O–Si–O bonds. Experimental results indicate...

Recycling is among the best management strategies to avoid dispersion of several types of wastes in the environment. Research in recycling strategies is gaining increased importance in view of Circular Economy principles. The exploitation of waste, or byproducts, as alternative aggregate in concrete, results in a reduction in the exploitation of scarce natural resources. On the other hand, a productive use of waste leads to a reduction in the landfilling of waste material through the transformation of waste into a resource. In this frame of reference, the paper discusses how to use concrete as a container of waste focusing on the waste produced in limestone quarries and taking the challenge of introducing plastic waste into ordinary concrete mixes. To prove the possibility of reaching this objective with acceptable loss of performance, the mechanical characteristics of concrete mixed with additional alternative aggregates classified as waste are investigated and discussed in this pa...
Characterization of some Key Industrial Waste Products for Sustainable Concrete Production
Advanced Materials Research, 2013
The use of environmentally friendly or "green" concrete to enable worldwide infrastructural development without increase in carbon dioxide (CO2) emission is at the focal point of the global issues concerning sustainability. Aside from the concerted efforts by the key players in the construction industry to successfully replace in part or in whole, the conventional Portland cement with green or eco-friendly cementitious materials, the challenges of ensuring that the so called green or eco-friendly concrete performs up to the required expectation has been the focus of many researches. This study therefore, provides an overview of the various processing techniques for the industrial waste materials as well as the determination of the physical and chemical characteristics of the powders prepared from the respective waste materials. The materials were characterized using BET surface area analysis, X-ray diffraction (XRD), Chemical analysis by X-ray fluorescence (XRF), 45-µm wet sieving, 75-µm and 150-µm dry sieving, Specific gravity using density bottle and reactivity index (RI). The results show that FA and PBC are very similar in terms of their physical and chemical characteristic in comparism with POFA. Notwithstanding, all the materials satisfy the basic requirements of the relevant ASTM specifications and also falls within the limit specified by ASTM C 618 for class F fly ash.
