The geopolymerization reaction is a chemical process involving the dissolution of
amorphous, semi-crystalline and crystalline phases following alkaline or acid attack at …

This paper presents the results of a study on developing optimized alkali-activated binders
(AABs) utilizing selected natural minerals and industrial byproducts as precursor materials in …

Given the insufficient mechanical performance of existing fly ash-based geopolymer mortars
under ambient curing conditions, this study is dedicated to developing a high-strength …

Quartz is the most common mineral in continental crust rocks. It has been used for multiple
industrial purposes. Herein, we have investigated the effect of aluminum (Al) additions on …

In this investigation, mechanical activation (MA) of pegmatite quarry wastes was perform via
an eccentric vibratory mill to improve the geopolymeric reactivity. The MA at miscellaneous …

In this work, geopolymer binders obtained from a mixture of Cameroonian pegmatite and
type 1/1 calcined clays (metakaolin and metahalloysite) at different proportions (10–30 wt%) …

Concrete structures built in granite-based aggregate develop and proliferate contour-like
cracks as they aged. Such cracks are often associated to alkali-aggregate reactions (AAR) …

A systematic study on the dissolution in concentrated alkali of two volcanic ashes from
Cameroon, denoted as DAR and VN, is presented here. One volcanic ash, DAR, was 2 wt …

The exploitation of volcanic rock quarries generates enormous waste, which causes the
problem of disposal, leading to rising dust levels in quarries and depositions on nearby …

This work aims to synthesize new cementitious materials (binders) using marble powder,
rice husk ash, activated laterite and NaOH solution by applying low energy process. The …
