A B VAJPAYEE LAYOUT   Is a huge Indian government residential housing project for 197.96 acres of area in chikkmagalur, Karnataka . The project involves 2,500 marked plots of different dimensions and are divided as A, B, C, D, E & F sectors. You can also check recent details about this projects on cuda( chikkamagalur urban devepment authority )  website:  http://www.cudackm.com/  . Plots here will be comparatively cheaper as compared to other places. Here is a picture to give you better understanding of it:  PLAN OF COMPLETE PROJECT The project is taken up by NCC( nagarjuna construction company ), which is usually more interested in housing projects. I hope this information was helpful, it's just an easy outline to make you aware about this ongoing project.😊  If you want any other information or have any questions about this please do comment.

6 important PROPERTIES OF CONCRETE IN FRESH AND HARDENED STATE PROPERTIES OF HARDENED CONCRETE   1. STRENGTH : Concrete is strong in compression but r fielatively weak in tension and bending. It takes a great deal of force to crush concrete, but very little force to pull it apart or cause bending cracks. Compressive strength is determined primarily by the amount of cement used, but is also affected by the ratio of water to cement, as well as proper mixing and placing, and the adequacy and extent of hydration and curing. Tensile strength usually ranges from 7 or 8 % of compressive strength in high-strength mixes to 11 or 12% in low-strength mixes. Both tensile strength and flexural bending strength can be increased by adding steel or fiber reinforcement. Required compressive strength is based on an analysis of the loads that will be applied and the soil conditions at the project site. Actual compressive strength is verified by testing samples in a la...
