IMPORTANCE OF CONCRETE IN RCC FRAME STRUCTURE FOR HIGH RISE BUILDINGS AND IMPORTANT INFRASTRUCTURES

Vikram Y Tambvekar, Mrunmayee V Tambvekar

Abstract: “Concrete” is versatile composite material being used in all type of RCC frame structure and for foundation of steel structure frame, machinery foundation, infrastructure like Dams, Bridges, concrete roads etc. In general the project consulting engineers / designers provides structural design details along with grade of concrete as per their design requirements & concept. Further while actual execution of the project, role of concrete is very important to get desired achievement for serviceability, durability of the structure designed. Concrete has been specified as: i) Normal grade concrete ii) structural grade concrete iii) High performance concrete (HPC). Water: Water must be checked for pH, chemical contents (chloride & sulphate), TDS etc., before using for concrete production. Proper mix proportion & effective use of chemical admixture shall be followed. Strength parameters & MOE (Modulus of Elasticity) shall be checked to meet requirements as per IS -456-2013. Durability: Durability of HPC shall be checked for following parameters: i) RCPT- (Rapid chloride penetration Test as per ASTM-1202 -2007 ii) WP (Water Permeability) as per DIN-1048 iii) MOE (Modulus of Elasticity) on concrete – as per IS-516 iv)Water Absorption of Water on concrete – as per BS -1881-part122-1983
