objective: evidence shows that the powder/liquid mixing ratio recommended by the manufacturers is often not respected when mixing the glass ionomer (gi) powder and liquid, yielding a gi cement with disproportionate powder/liquid ratio. considering the confirmed effect of powder/liquid ratio on the gi properties, and more importantly, its fluoride release potential, this study aimed to assess th...

Recycled powder is a kind of particle with size less than 75 ?m produced in the process preparing recycled aggregate from construction waste concrete and brick as main components. It has potential to replace part cement an auxiliary cementitious material. This important engineering application value for promoting full-component high-quality utilization waste, which meets needs national sustaina...

Glass cullet (recycled or broken glass) has been proposed to replace dredged sediment in beach and river recovery processes after severe weather events. Dredging of the ocean floor lost on beaches led many negative environmental impacts, such as disturbance marine ecosystems, notably death both animal plant life near coastlines. The majority that for replacement is float glass, not bottle glass...

The exponential expansion in concrete use has put the environment under immense pressure to supply cement, aggregates, and water. Natural resource consumption impacts undermines industry. A swift shift towards sustainable is required considering emergency triggered by human activity on climate. Glass (GC) sparked curiosity of construction industry owing its environmentally friendly approach. st...

Clay brick and granite waste are part of the generated by construction demolition activities. The amount these wastes is enormous, but on one hand, they can be used as a raw material for cement mixtures; thus, it important to find ways utilize them efficiently. In this study, clay were crushed screened into two size fractions (0.15–2.36 mm sand replacement smaller than 0.15 replacement), total ...
