Effect of Cement Types on Mechanical Strength, Durability, and Unit Production Cost of Concrete
The primary aim of the present study is to identify the optimal cement type by jointly assessing mechanical performance, durability performance, and cost‐effectiveness using multicriteria decision‐making (MCDM) approaches. This study investigates the effects of four cement types commonly used in Bangladesh—CEM I/OPC, CEM II/A‐M (S‐V‐L), CEM II/B‐M (S‐V‐

This study investigated the suitability of natural cinder gravel blended with fine‐crushed aggregates as a base course pavement material using laboratory tests and numerical simulations. Laboratory test results for natural cinder gravel indicated that cinder gravel alone failed to meet the Ethiopian Roads Authority (ERA) standard specifications for ...

Synthesis and Characterization of Metakaolin‐Based Geopolymer for Industrial Application
Materials with enhanced properties are currently in high demand. Consequently, the ability to synthesize these materials efficiently, using low energy and without adverse environmental impact, has become a critical research priority. For this reason, geopolymers present an attractive prospect for researchers in material science and engineering. In this

Portland cement production is a major contributor to global CO2 emissions, and the scarcity of natural river sand limits conventional concrete production. Despite increasing interest in geopolymer concrete (GPC), studies on sustainable, low‐temperature cured GPC using industrial by‐products as fine aggregate replacements are limited.
