State-of-the-Art Report on Fiber-Reinforced Lightweight Aggregate Concrete Masonry

Abstract

Masonry construction is the most widely used building method in the world. Concrete masonry is relatively low in cost due to the vast availability of aggregates used within the production process. ese aggregate materials are not always reliable for structural use. One of the principal issues associated with masonry is the brittleness of the unit. When subject to seismic loads, the brittleness of the masonry magni es. In regions with high seismic activity and unspeci ed building codes or standards, masonry housing has developed into a death trap for countless individuals. A common approach concerning the issue associated with the brittle characteristic of masonry is addition of steel reinforcement. However, this can be expensive, highly dependent on skillfulness of labor, and particularly dependent on the quality of available steel. A proposed solution presented in this investigation consists of introducing steel bers to the lightweight aggregate concrete masonry mix. Previous investigations in the eld of lightweight aggregate ber-reinforced concrete have shown an increase in exural strength, toughness, and ductility. e outcome of this research project provides invaluable data for the production of a ductile masonry unit capable of withstanding seismic loads for prolonged periods.

Literature review on steel fibre, silica fume and fly ash: improving methods for recycled and multiple recycled aggregate concretes

“…Rico et al [9] added steel fibres into a delicate cement matrix, according to their research, in order to increase the break resistance of the LWC by the split capture process and to improve the tensile and flexural properties. The results showed that steel fibre played a connection role inside the concrete thus helping to raise the resistance of the concrete against cracks and mentioned that increased toughness is a consequence of increased fibre.…”

Utilization of Biomass Flyash in Cementitious Application

“…This is the unbranded residue that happens when the coal is finely ground at or above 75 percent and then removed from the hot area. Fly-ash is composed of 10-40% non-fuel impurities (for example, clay, shale, quartz, feldspar, dolomite, Silestone), depending on the source and grade, [11,12]. Fly Ash is non-fuel flue gas impurities after the complete combustion of high furnace temperatures of volatile and carbon flows.…”

“…As ash of fly, mechanical and electro-static connectors are used to manage the mentioned flue gas stream, while the denser, unbranded material flows to the base of the stove and is mainly called ash of fly. At present, it is estimated that worldwide fly ash production amounts to 600 million tons [11,12]. Ashes as fresh concrete characteristics, such as quality, size, shape, strength, and color, depend primarily on collecting new concrete and temperature of carbon burning [11][12][13].…”

Textiles and Fabrics for Enhanced Structural Glass Facades: Potentials and Challenges

“…The typical application consists of textile reinforced mortars in which fibre filaments act in place of steel rebars (see Section 2 and [4][5][6]). The actual result can take the form of efficient technical solutions that are suitable especially for existing (and often historical) buildings needing massive, structural retrofit interventions, especially in regions with high seismic hazards ( [7][8][9][10]).…”
