An Experimental Investigation on the Performance of Green Concrete Mixes
摘要
Green concrete is a variety of concrete that is manufactured utilizing eco-friendly materials and methods. Green concrete can be manufactured by utilizing various materials such as recycled concrete aggregate, fly ash, slag, and other industrial wastes. These materials are utilized to decrease carbon emissions in the production of concrete and to preserve natural resources. Moreover, green concrete can be engineered to possess enhanced durability and performance in comparison to conventional concrete, hence aiding in the reduction of maintenance and repair expenses over the lifespan of a building. In summary, green concrete is a significant advancement in the construction sector that can facilitate the adoption of sustainable building methods and mitigate the environmental consequences of concrete production. In this research, three different combinations of materials have been utilized to produce concrete cubes. The purpose was to evaluate the mechanical properties of the concrete, namely its split tensile strength and compressive strength. Trial mix-1 incorporates 30% fly ash and 20% GGBS as substitute for cement, 30% stone dust as a replacement for sand, and 30% RCA as a substitute for natural aggregates. In contrast, Trial 2 utilizes 25% fly ash and 25% GGBS, with the remaining components being the same as Mix 1. The split tensile and compressive strength of trial mixes 1 and trial mixes 2 were found to be similar to that of normal mix concrete. The results obtained were encouraging as the strength remained comparable even after substituting a significant portion of concrete with industrial waste materials. The green concrete mixes exhibit higher split tensile strength and compressive strength compared to conventional concrete mixes.
