  • EcoFriendly Alternatives To Traditional Concrete

    Posted on July 18, 2019 Concrete is a mixture of cement, gravel, sand, water and a range of aggregates With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water It is also the world’s most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructureReplacement of Cement in Concrete P Vipul Naidu1 and Pawan Kumar Pandey2 1CivilSOT, Pandit Deendayal Petroleum University, Raysan, Gandhinagar, INDIA 2Engineer, DMRC, Sector18, Rohini, New Delhi, INDIA Abstract Cement is a binding material, a substance that sets and hardens independently, and can bind other materials togetherReplacement of Cement in ConcreteConstruction methods of embankments on soft soils 3 Figure 12 Execution schedule for soft soil replacement: (A) and (B) excavation and removal of soft soil;(C) and (D) filling of the hole;(E) replaced soil (final condition) equipment trafficConstruction methods of embankments on soft soils
