The researchers at Rice University showed uses of fly ash by building a composite flash binders, and these flash binders are expected to be a substitute for Portland cement in concrete. Several benefits of rice materials ensure that the constructions industry forges a more environment-friendly framework. Since the material is cementless, it is substantially different from the conventional concrete used in the current day structures and buildings. Moreover, Portland cement requires high temperatures to process whereas the new materials made do not require such heavy temperatures. Despite this anomaly of the new materials, the concrete strength of the material is same as Portland cement. Sodium-based chemicals for activation are also required in lesser quantities as against Portland cement.
The production of concrete cement across the world is estimated to be 20 billion tonnes each year. This results in 5-10% of total carbon emission coming from the manufacture of cement for concrete. Hence, it is only the energy and transportation sector that supersedes the cement industry in terms of contribution to greenhouse gases. Portland cement is sometimes blended with aluminium and silicon, which further emphasizes on the relevance of rice cement.
The problems of sustainability in the constructions industry could be resolved with the usage of the rice materials. The efforts of several stakeholders and promoters of environmental sustainability will also be aided by the new materials.
