Quarry dust is the crusher waste of granite quarries which is about 13-15 % of the total quarry products and accumulation of this waste generates environmental issues. For the past three decades, the scarcity of river sand has been taken seriously and research initiated to replace it with quarry dust either in the available form, or fines removed or processed sand. The presence of very fine particles found as 5-8% demands for increased water cement ratio for better workability which could reduce the strength of the concrete. Therefore it is emphasized, to replace cement partially with these fi

Abstract This study investigates the impact of waste additives on the behaviour of high-performance concrete and its environmental implications, with a specific focus on resource conservation. The research objectives were realised through the preparation of high-performance concrete specimens incorporating industrial waste materials and marble powder as partial replacements for cement and fine aggregates, respectively. Silica fume and ground blast furnace slag were introduced as substitutes for 8% of the cement’s weight. Powdered marble was volumetrically substituted at levels of 5%, 10%, and

Media visual sculpture is a landscape element with high carbon emissions. To reduce carbon emission in the process of creating and displaying visual art and structures (visual communication), geo-polymer concrete (GePC) is considered by designers. It has emerged as an environmentally friendly substitute for traditional concrete, boasting reduced carbon emissions and improved longevity. This research delves into the prediction of the compressive strength of GePC (CSGePC) employing various soft computing techniques, namely SVR, ANNs, ANFISs, and hybrid methodologies combining Genetic Algorithm (

In order to support the environment, sustainable construction is one solution that can be implemented by utilizing construction waste efficiently. Every year, tons of concrete waste is generated and it is necessary to utilize the waste as a recycled material such as recycled aggregate. Production of cement for concrete also increases carbon dioxide (CO2) emissions in the air resulting from factory processing.

The mineral additive used is natural pozzolan found in large quantities in Western Algeria (Béni-Saf); however, it must be beneficiated. To do so, we designed three pozzolan-based concretes (20, 25, and 30%). We measured compressive strengths at various times and produced a reference control concrete for com

Moreover, post-fire properties of concrete are influenced by the constituents of each concrete type.
