Role of Ground Glass Fiber as a Pozzolan in Portland Cement Concrete
Millions of tons of fiberglass are produced annually for a variety of applications. Because of stringent quality requirements and operational characteristics of the manufacturing plants, a significant quantity of fiberglass that does not meet required specifications of the industry ends up as waste in landfills.

The construction industry significantly contributes to global CO2 emissions, with cement production being a major factor. Concurrently, large quantities of crushed fly ash brick (CFAB) waste accumulate due to manufacturing defects. In this study, CFAB powder was developed as a supplementary cementitious material (SCM) by partially replacing cement in ...

Rapid industrialization and urban growth have driven a rising demand for cement, yet ordinary Portland cement (OPC) production remains energy‐intensive and a major source of CO2 emissions. The partial substitution of OPC with supplementary cementitious materials (SCMs) offers a sustainable route to reduce environmental impact, production costs, and ...

Currently, many researchers use industrial or agricultural by‐products (waste) as raw materials for the construction sector. These wastes are economical and help preserve the environment through good waste management. For this purpose, oil palm mesocarp fibers (OPMFs) are used at various volume concentrations (0%, 0.25%, 0.5%, and 1%) for the ...

Performance of Concrete Using Water Hyacinth Ash as a Partial Cement Substitute
Concrete is one of the most widely used construction materials, with cement as its primary component. However, cement production significantly contributes to CO2 emissions, posing environmental challenges. This study investigates the use of water hyacinth ash (WHA) as a sustainable partial replacement for cement in C‐30 grade concrete.

This study explores the partial replacement of ordinary Portland cement (OPC) with a composite of eggshell powder (ESP) and wheat straw ash (WSA) in C‐25 concrete, focusing on mechanical performance and durability. Cement was replaced with varying proportions of ESP and WSA, and the concrete mix was prepared following ACI guidelines.
