As the demand for cement supply is continually growing, this causes an increase in the use of aggregate, especially limestone since it is important in the production of Portland cement [13], [14].Exhaustion of the earth's non-renewable resources is a growing dilemma when the reason is that the energy consumption has …
The experimental results indicate that use of limestone quarry waste and use of plastic waste are possible within significant percentage ranges, having recognized a limited reduction of concrete …
Concrete is among the world's most consumed materials—second only to water. 1 That's because its durability, affordability, and availability make it essential to countless construction projects, from bridges, to roads, to buildings. Since concrete is used on such a large scale, it also produces large amounts of heat-trapping greenhouse …
In quarrying activities, rock is extracted and transformed into aggregate of various sizes for civil engineering applications. In this process waste fine aggregates (dust waste) are generated. The disposal of this type of waste is a further cost in the extraction process, but also a possible cause of environmental pollution (e.g. leaching into water …
The first experimental investigation refers to concrete made with fine limestone waste used as a replacement for fine aggregate (sand), while the second experimental program refers to the ...
Limestone aggregate concrete typically has a lower carbon footprint than traditional concrete, mostly due to the composition of its primary ingredient, limestone aggregate. While both types of concrete use Portland cement as a binder, limestone aggregate concrete substitutes crushed limestone for some of the traditional sand and …
The replacement proportion of sand with limestone waste, 25%, 50%, and 75% were practiced in the concrete mixes except in the concrete mix. Besides, proportions of 5%, 10% and 15% marble powder ...
The shortage in naturals aggregate has led to a significant increase in limestone usage as aggregate in concrete production around the world [53]. The coarse aggregate largely affects the concrete ...
Concrete, an indispensable cornerstone of the construction industry, presents a formidable environmental challenge owing to the substantial carbon dioxide (CO2) emissions incurred during the production of cement. However, in light of the construction sector's vital economic and social contributions, it becomes imperative to harmonize it …
In this recent work, ceramic tiles wastes (CW) were utilized as coarse aggregates in different weight fraction ratios starting with 10% till at an increment of 10% in production of normal concrete. Also, 5% of cement weight was substituted via using limestone powder (LP). Slump value, fresh and dry density, absorption ratio and …
This article analyses the effect of modifying cement concrete with waste limestone powder as a partial substitution for fine aggregate. The analysed waste arises as a result of the accumulation of dust produced during the initial preparation of aggregate for the production of hot mix asphalt (HMA). In order to analyse the effect of waste on ...
