Cement concrete and other cement-based composites find wide application in the construction industry. The manufacturing of cement releases a large amount CO2, so use has become major area environmental concern. Attempts have been made to minimize quantity con- crete by replacing it with supplementary cementitious materials. Geopolymer is one those potential candidates for alternative mate- rial...

Abstract Despitethe increasing number of publications on residual raw materials as supplementary cementitious (SCM), the milling beneficiation process and its parameters have been underexplored presented. In this context, study aims to evaluate for marble, clay tile, brick, phosphogypsum waste processing recycling SCM. The were benefitted by grinding, sieving, in a planetary ball mill, varying ...

Sustainable building should at least be affordable and carbon neutral. Sub-Saharan Africa (SSA) is a region struggling with housing affordability. Residential buildings are often constructed using block-based materials. These increasingly produced ordinary Portland cement (PC), which has high footprint. Using alternative Supplementary Cementitious Materials (SCMs) for block production might red...

Solar light with high-energy ultraviolet (UV) radiation acting on the surface of cement-based materials easily changes properties by affecting their carbonation reaction. In order to elucidate difference in process under UV different supplementary cementitious (SCMs), depth (apparent pH values), chemical composition (XRD, FTIR, and TG analysis), mechanical (compressive strength microhardness) w...

Designing self-healing into cementitious materials can open a new world of opportunities for resilient concrete infrastructure under service loading conditions. The self-healing process should be robust as well as repeatable, allowing for self-repair after multiple damage events. The repeatability poses great challenges when self-healing strategies mainly rely on the formation of low-strength c...

Synopsis: Cementitious materials are generally classified as semi-conductors that are capable of carrying electricity when an external electrical signal is applied. The electrical properties of cementitious materials have been widely explored for monitoring their internal hydration processes. However, comparatively less work has been done in using the inherent electrical properties of cementiti...
