| Abstrait: |
This study concerns the application of a water-saving cement additive that can appreciably better the hardened properties of a cured product of a cementitious composition over a long time period. This advanced cement additive is a Nanotechnology based advanced material also known as Nano Materials at varying dosages by weight of ordinary Portland cement (1 part by weight) in a dry mix with river sand constituting 3 parts by weight of cement. Nanomaterials are insoluble in water so it’s dissolved in a polymeric compound of Polycarboxylate Ether through ultrasonication.7.07cm cubes are cast with this mixture with water adjoined as per IS:4031 Standards under the fixed water/cement(w/c) at 0.4. After casting the cubes are cured at room temperature and they are tested for 3 Days, 7 Days, 28 Days, & 365 Days for compressive strength. Not only the results when compared are found to be superior to that of the ordinary cement composite cubes but also were found to be much more economical when compared to Silica Fumed cement compositions. |
