Review of Recent Development Regarding Strength, Durability, and Microstructure Properties of Geopolymer Concrete Containing Rice Husk Ash

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Due to the growing infrastructure and the demand for environmentally friendly environments, the use of concrete as a construction material is gradually rising. Since concrete is the second‐most utilized material after water, it is necessary to employ alternative, sustainable materials, particularly those derived from waste.

Efficiency of Bagasse Ash Incorporated With Limestone Calcined Clay Cement on Improvement of Geotechnical Properties of Black Cotton Soils: A Cleaner Approach

Journal of Engineering, Volume 2025, Issue 1, 2025.
This study is aimed at investigating the effect of sugarcane bagasse ash (BA) incorporated with limestone calcined clay cement (LC3) as potential alternative from technical, ecological and economic perspectives of black cotton soil (BCS) stabilisation. BA incorporating LC3 material was added to BCS having high swell degree, in mix proportions of 0%–18%.

Use of metakaolins from Eseka and Dibamba‐Cameroon as an optimization additive of CEM I Portland cement mortar

International Journal of Ceramic Engineering &Science, Volume 6, Issue 6, November 2024.
Abstract The present study deals with two kaolins from Eseka and Dibamba‐Cameroon to determine their potential suitability as additive of CEM I 42.5R and to optimize the properties of cement in the sense to promote low‐carbon cement. X‐ray diffractometry was used to establish the mineralogical composition of two kaolins.

Slags from roasting of antimony ore in the Brioude‐Massiac (France) area used as aggregates: An early example of circular economy

Journal of Microscopy, Volume 294, Issue 2, Page 75-83, May 2024.
Abstract Towards the end of the 19th century and the early 20th century, France was the world's largest producer of antimony, especially due to the rich deposits in the Brioude‐Massiac area. Even though all the mining and smelting activities are long gone, there are still some remains of those activities.

Effect of Natural Pozzolana on Physical and Mechanical Properties of Concrete

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Construction industries are rapidly growing, sacking high amounts of concrete which has a highly dense microstructure with excellent mechanical properties, more durable, and highly eco‐friendly materials. Hence, many of the researchers are interested in solving this problem with replacing concrete by natural pozzolana (NP) which is a supplementary ...

Cement‐Stabilized Granular Volcanic Ash Materials for Construction of Low‐Traffic Roads in Yemen

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Granular volcanic ash (GVA) is a volcanic activity material with low density, high porosity, and other undesirable properties that must be improved prior to use in any construction. This material can be considered an alternative for use in road building, given its availability in many locations and in large quantities in Yemen.

Mechanical Strength and Microstructure of Soft Soil Stabilized with Cement, Lime, and Metakaolin‐Based Geopolymer Stabilizers

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Soft soils require particular consideration when designing civil engineering structures due to their high compressibility, low shear strength, and permeability. Using chemical additives and geopolymers to stabilize soft soils is a practical approach to improve their engineering properties.

Development of Strength‐Maturity Relationship for Coral Sand Concrete Incorporating Bamboo Leaf Ash

Advances in Materials Science and Engineering, Volume 2024, Issue 1, 2024.
In this study, the maturity concept was applied to predict the compressive strength of coral sand concrete incorporating bamboo leaf ash as a cement replacement material. The use of coral sand concrete is restricted due to drawbacks such as low compressive strength, which result from the brittleness and high breakage of coral sand.
