Effect of Compression Pressure on the Strength and Fuel Properties of Maize Cob Briquettes
Abstract: Biomass can be densified under a high compression pressure or a low compression pressure. The type of raw material, moisture level, particle size, and form typically all influence how much pressure should be used. This study utilized maize cobs and waste paper pulp to produce briquettes which are seen as alternative fuels. The goal was to determine how compression pressure affected the strength and fuel characteristics of the briquettes that …

Techno-Economic Analysis of Packed Bed Type Thermal Batteries for Surplus Renewable Energy Storage
Abstract: Low carbon electricity from renewables will form the bed rock of the energy transition necessary for climate change mitigation. However, variable renewable generators suffer from intermittency and variability – there can be large surplus power available at times which cannot be dispatched to the grid. At many times, the practice is to curtail surplus renewable output, which is wasteful and not economic. There are also phases when generation is not …

Study of Durability Properties of Bagasse Ash Concrete and Its Behaviour when Exposed to Elevated Temperatures
Abstract: The major driver for the economic growth and social progress of any country is its construction sector. In India, it is estimated that construction contributes 8% to 9% to GDP and this share is likely to increase in coming years. High-performance concrete made from ordinary Portland cement (OPC) and various supplementary cementitious materials (SCM) are alarmingly finding their use in construction worldwide. Bagasse ash (BA), one such SCM, the agro-industrial …

Fracture and Failure of Recycled Aggregate Concrete (RAC) – A Review
Abstract: In the world, many countries put into effect the renewal plans and/or the laws and/or the regulations for recent engineering structures which have reached their lifetime, are risk prone and have been built lacking quality engineering, or without considering urban planning. Hence, many structures are demolished and this situation increases the amount of construction and demolition waste (C & DW). Also, resource consumptions are rapidly increased due to excessive constructional …

Influence of GGBFS on the Mechanical Properties of the Water Cured Fly Ash Aggregate-Based Geopolymer Concrete
Abstract: Abstract Conventional concrete consists of cement, sand as fine aggregate and gravel, limestone or granite in various sizes and shapes as coarse aggregate including with water. In the present work, the feasibility of using industrial inorganic polymeric residues wastes as a total (100%) replacement to the traditionally used normal conventional concrete materials is examined in the preparation of the geopolymer concrete (GPC). In this GPC, the cement is totally replaced …
