Abstract
Increase in the paper waste from paper industries become most serious disposal problem by occupying large space and environmental pollution which is raising every day. To reduce the paper waste and environmental pollution, it is proposed to use the paper waste as Hypo sludge in concrete mix which contains cementitious properties like silica and magnesium. The main ingredient of concrete is cement. During the manufacturing of cement, large amount of carbon dioxide is released into the environment which causes global warming. To control environmental pollution from cement industries, Hypo sludge is used as a partial replacement of cement so that it can reduce cement content and support as an eco-friendly building material. In this research cement is replaced with fly ash and Hypo sludge. By adding 0 percent,3 percent,6 percent,9 percent 12percent and 15percent of hypo sludge, compressive and split tensile strength of concrete and also performance of Hypo sludge concrete are studied. From the experiment, compressive strength and split tensile strength of Hypo sludge concrete increases up to optimum dosage.
Highlights
Energy plays a vital role in developing countries production
Volume of carbon dioxide is released into the atmosphere to create one ton of Portland cement is of same quantity, which results in greenhouse effect
In order to save the world from global warming, various cement binders with cement products such as hypo sludge, fly ash, silica fume, GGBS, metakoline etc. should be substituted in cement
Summary
The value of using industrial waste is very important due to the low availability of nonrenewable energy resources, along with the demands of large quantities of energy for building materials like cement. Portland cement plays an important role in construction. To minimise the problems of pollution and disposal from these industrial waste, it is utmost important to create useful building materials from the waste. The H.Sludge includes low calcium, high calcium chloride and minimal quantity of silica and behaves like mortar due to the properties of calcium and magnesium. This reduces the concrete life because of the presence of toxic gasses found in the environment. This paper discusses in a concise way the technological and environmental benefits of using additional cemented components, as well as the drawbacks, requirements and specifications
