Abstract
Cement is a fine binding material that sets and strengthens when water is added to it. It is largely used in construction with great advantage, but cement, with its wide range of properties, has several disadvantages as well. Manufacturing cement causes ill effects on the environment at all stages of the process. These include emission of pollution like dust, gas, to carbon dioxide, from 5% in cement structures to 8% in the case of cement roads. Carbon dioxide is released by cement manufacturing both indirectly (emission of energy) and directly (heating of calcium carbonate). The cement factories produce up to 5% of global CO emissions. This review paper presents the usage of fly ash by replacing cement and robo sand with fine aggregate in our general construction. In addition, a review of the effect of steel fibers on concrete is also done. By replacing fly ash with cement and fine aggregate with Robo sand, we got results.
