Utilization of Brick Dust and Rice Husk Ash for Sustainable Cement Replacement in M20 Grade Concrete
Abstract: AbstractThe study evaluates the influence of replacing cement with Fly Ash, Brick Dust, and Rice HuskAsh on the compressive strength of concrete. Cement replacement was conducted at varyingpercentages (5%, 10%, 15%, 20%, 25%, 30%, 35%, and 40%) for M20 grade concrete, andcompressive strength was assessed at 7, 28, 90, and 180 days. The results demonstrate thatpartial cement replacement can achieve comparable or improved strength performance up to anoptimal level, beyond …

Investigating Physical and Durability Properties of Pervious Concrete with Fly Ash-Based GP, PPC, and FaL-G Binders
Abstract: AbstractPervious concrete is gaining prominence as a sustainable pavement material due to its enhancedpermeability, reduced runoff, and environmental benefits. This study evaluates the physical anddurability properties of pervious concrete incorporating different binders, including OrdinaryPortland Cement (OPC), Fly Ash-based Geopolymer (GP), Portland Pozzolana Cement (PPC),and Fly Ash-Lime-Gypsum (FaL-G). The key parameters assessed include permeability,porosity, dry density, salt resistance, sulfate resistance, acid resistance, water absorption, andthermal expansion. Permeability results indicate that FaL-G …

Laboratory Scale Study on Fly Ash Replacement to Cement in High-Strength Concrete
Abstract: Abstract Concrete, the cornerstone of modern infrastructure, faces increasing environmental impact of cement production calls for sustainable alternatives in construction materials. Primarily due to the high carbon footprint associated with Portland cement production. This review synthesizes existing research and the findings from an experimental study investigating the partial replacement of Ordinary Portland Cement (OPC) with fly ash in high-strength concrete (HSC) of grade M60. The study specifically examines a 50% …

Smart Technologies for the Modernization of Ready-Mix Concrete Operation
Abstract: Abstract Ready-mix concrete is a product that is ready to use. It is made up of cement, sand, aggregate, and water.In accordance with client requirements, a transit mixer transports the combined material to the location.Ten years ago, ready-mix concrete was first introduced to the Indian construction industry; however, itshigh tax rates and excessive costs initially hindered its widespread use. However, it became more popularbecause it required less strength, time, and …

BEHAVIORAL STUDY OF REINFORCED CONCRETE BUILDINGS DURING MAINSHOCK–AFTERSHOCK EARTHQUAKES
Abstract: ABSTRACT - Earthquakes are among most destructive natural hazards, often causing widespread damage to buildings and vital infrastructure. The extent of this damage depends on various factors, one of which is the nature of fault movement. The point of initial rupture beneath the Earth’s surface is known as the hypocenter or focus. Seismic activity can be broadly divided into two categories: mainshocks and aftershocks. While the mainshock generally causes the …
