Development and Feasibility Analysis of Bagasse Ash Bricks

AbstractSugarcane bagasse ash (SBA), which is otherwise landfilled, was utilized to develop construction material that serves a purpose of disposal of solid waste management and energy efficient alternate construction material. SBA was characterized using particle size distribution, scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). SEM monographs show the rough surface with plenty of fine pores. XRF, XRD, and physicochemical properties of the SBA prove its suitability as a pozzolanic or cementitious material. TGA confirms thermal stability till 650°C. On the suitability of principal raw material, SBA–quarry dust (QD)–lime (L) bricks were developed with a constant composition of lime (20% by weight) and tested for physicomechanical (weight, dry density, water absorption, efflorescence, and compressive strength), functional (thermal conductivity, k), durability (chloride, sulfate, and carbonation), and environmental [toxicity charact...

Analyzing the Strength Behavior of Cement Composites with Waste Glass Fibers

Cement composites fail due to tensile strains exceeding their limiting strain capacity. This results into development of cracks and gradual loss of strength. The controlling of cracks is vital for better fatigue performance of concrete construction. The paper presents a study of the suitability of waste glass fibers for utilization in cement mortar and concrete specimens in order to promote sustainable construction. These fibers were added to the composites by weight fraction, and relevant tests were performed on them. Test results indicate that cement mortar showed an increase in strength and a pseudo-ductile behavior due to addition of fibers. while concrete specimens showed loss in compressive and flexural strength.

Application of Solid Wastes for the Production of Sustainable Concrete

The production of concrete results in emissions of about 0.13 t of CO2 per ton of concrete, equal to 1/9th the emissions of cement. The tremendous usage of conventional raw material creates a negative impact on the concrete industry which can be minimized by the application of solid wastes as a raw material. The present paper reviews various solid wastes in different compositions to develop sustainable concrete. In view of the utilization of agro-industrial wastes as a pozzolanic material, their physical and chemical characterizations were reviewed. The crushing strength of high strength concrete incorporated with various agro-industrial wastes as a pozzolanic material was studied. This paper also proposes a procedure for producing manufactured coarse aggregates made of solid waste (i.e. sediment dredged from dam reservoir). The crushing strength of concrete incorporating the manufactured coarse aggregates was experimentally measured. Along with it, the physico-mechanical properties of the artificial sand, produced using the industrial solid wastes (i.e. fly ash) were analyzed. Reusing of solid waste as a substitute raw material will not only solve its disposal problems but also serves as an economical option to develop the sustainable concrete. The present paper is useful for various researchers involved in using solid wastes to develop the sustainable concrete.

Application of AV-ERP system for on-site project monitoring

Purpose – The purpose of this paper is to report the results of a techno-economic feasibility study on the application of Audio Visual Enterprise Resource Planning (AV-ERP). Due to rapid urbanisation and economic growth in developing countries (DCs) like India, there has been tremendous development in infrastructural projects. To maintain the quality and competitive commercial pricing of the projects, stakeholders are working together from different geographic locations. Due to lack of culture in adopting the technological advancements, the on-site construction activities lack coordination among the stakeholders. Design/methodology/approach – In the present case, it is observed that the site and various stakeholders like consultants are physically monitoring and controlling the ongoing construction activity from different geographic locations. To manage the effective communication and information exchanges, an integrated tool for surveillance and AV-ERP is proposed in the present paper. These equipment an...
