The use of supplementary cementitious materials (SCMs) has increased over the years due to the carbon footprint associated with the production of cement, which contributes to 10% of the total global CO2 gas emissions. This causes an increase in global warming, and the exponential increase in demand for construction of concrete has …

Experimental studies are carried out with addition of 0.5%, 0.75% and 1% polypropylene fibres in both natural aggregate concrete (NAC) and recycled aggregate concrete (RAC). The recycled aggregate concrete is prepared with 100% replacement of recycled coarse aggregates with natural coarse aggregates. The present study reveals …

The conventional production of soil stabilizers, such as lime and cement, is associated with considerable energy consumption and pollution [5], with each ton of cement production emitting a similar amount of carbon dioxide into the atmosphere [6]. The advent of fiber-reinforced soils presents a promising alternative to enhance soil properties [7].
