Abstract:
The possibility of recycling large-tonnage waste of heat power engineer-ing and mining industry in road construction is shown. Compositions of road-building materials were researched, containing siftings of rock grinding, fly ash, Portland cement, modified with a stabilizing additive of polymeric nature. X-ray phase analysis showed availability of quartz in fly ash, calcite, feldspars, goethite and X-ray amorphous phase, what is consistent with the data of infrared spectroscopy. By atomic emission spectrometry with inductively coupled plasma it was revealed that fly ash is latent-active and ca

Abstract:
Fly Ash, known for its proven stability for variety of applications as admixture in cement, concrete, mortar, lime pozzolan mixture (bricks. blocks) etc, is an industrial by-product from Thermal Power Plants with current annual generation of approximately 108 million tones. Fly Ash is not just environment friendly, but is known for its cost effectiveness as well. Its use as a building material helps increase buildings strength and stability. Fly Ash is believed to be a very promising alternative for the industry seeking to meet its development objectives. Fly Ash is being very effectively and

Abstract:
The environmental impacts of natural aggregates (NA) and recycled concrete aggregates (RCA) production for use in road pavements have been evaluated in this study through an attributional life cycle assessment (LCA) from cradle to gate. Such effort is relevant considering the increasing interest of national agencies in applying recycled aggregates for construction and rehabilitation (C&R) of highway infrastructures. The study used site-specific data from two different aggregate production plants, stationary and mobile, both located in the northern region of Colombia. The stationary facilit

Abstract:
Over the past years there has been an increasing interest in recycling construction materials, particularly hot-mix asphalt (HMA) and portland cement concrete pavements (PCCP). To this end the Kansas Department of Transportation (KDOT) participated in Demonstration Project 47, Recycling Portland Cement Concrete Pavement, by recycling a moderately D-cracked concrete pavement and monitoring the performance over a 10-year period. The recycled concrete pavement (RCP) aggregate was evaluated in four test sections consisting of two control sections, one test section of portland cement-treated base (

This review presents “a state of the art” report on sustainability in construction materials. The authors propose different solutions to make the concrete industry more environmentally friendly in order to reduce greenhouse gases emissions and consumption of non-renewable resources. Part 1—the present paper—focuses on the use of binders alternative to Portland cement, including sulfoaluminate cements, alkali-activated materials, and geopolymers. Part 2 will be dedicated to traditional Portland-free binders and waste management and recycling in mortar and concrete production.

The article presents the results of utilization of blast furnace slags as a source for preparation of clinker-free cement materials for road and civil construction. Simple and high-yield approach for mechanical activation of metallurgical slag with cheap chemical modifiers using Vortex Electromagnetic Activation (VEA) technique was demonstrated to produce cement with high mechanical properties. Such approach may be used for effective and low-energy utilization of industrial scale-produced slags in concrete materials.

Abstract:
Although fly-ash as a partial replacement for cement has been utilized for many years, its use has been almost exclusively used in low volume percentages such as 10% or 20% cement replacement. This paper looks at high volume percentage replacements from 40% to 70%. A mini-mix study revealed that 50% and 60% cement replacement percentages were the best candidates for full scale testing. The environmental benefits included a 25% reduction in smog, human health, and fossil fuel reduction compared to the same element built with 100% Portland cement mix. The economic benefits included a 15% capital

This article demonstrates the possibility of producing alkali-activated materials (AAM) from a mixture of mechanically processed concrete, ceramic, masonry, and mortar wastes, as a sustainable alternative for recycling construction and demolition wastes (CDWs) under real conditions. The addition of 10% Portland cement allowed the materials to cure at room temperature (25 °C). CDW binder achieved a compressive strength of up to 43.9 MPa and it was classified as a general use and low heat of hydration cement according to ASTM C1157.

The City of Saskatoon is responsible for maintaining approximately 1,100 km of roads including locals, collectors, arterials, and freeways. With the aged state of the road infrastructure, increasing budget constraints limit the City’s ability to maintain existing road infrastructure to an acceptable level of service and to construct new road infrastructure. The infrastructure demands related to urban growth within the City of Saskatoon have caused a shrinking aggregate supply and increasing aggregate demand. In turn, growing demand and dwindling resources for aggregate are resulting in rapi

Abstract:
Increase in urbanization leads to more construction of houses, dams, and streets. Reduction of the global warming effects can be carried out by recycling of construction material and searching for eco-friendly construction material. Greenhouse gas emissions can be reduced with the help of construction material which requires less energy for their production. The concept of eco-friendly construction is based on biomimetic (i.e., finding natural material with potential of endurance and self-cleaning properties). Construction materials like Portland cement and concrete can be replaced by eco-friendly biocement and bioconcrete. Production of biocement and bioconcrete can be done by using plants, algae, and bacteria. Use of less cement in concrete leads to less pollution. Concrete is the mixture of cement, sand, gravel, and water. By addition of pozzolan in concrete, the requirement of cement will be reduced. In the current review, major emphasis is given to eco-friendly construction material.

Abstract:
Coal, as a fossil fuel, is used to generate power for industrial operation. Two types of industrial ash, including fly and bottom ash, which are solid residues arising from coal burning, are dumped to the landfill with no care for reuse. These wastes consist of environmental issues needing to be resolved. The ashes are used in the production of cement, concrete, aggregates, adobe, brick, and insulation material, in the construction of dam and road, and in geotechnical applications. Construction material is a form of cementitious materials based on ash as source material and it is an environmentally friendly choice against Portland cement releasing a large amount of greenhouse gas to the atmosphere during energy intensive manufacturing process. It is a good alternative to the solution of environmental problems based on the waste ashes in the international scale. In addition to its economic benefits, it is suitable for industrial symbiosis. This chapter explores the reusability of ashes for the building sector to strengthen the sustainability of waste management.
