AN EXPERIMENTAL STUDY ON STRENGTH AND PERMEABILITY PROPERTIES OF HIGH STRENGTH CONCRETE

Description

Concrete is the most important engineering material and the addition of some other materials may change the properties of concrete. Mineral additions which are also known as mineral admixtures have been used with cements for many years. There are two types of materials crystalline and non crystalline. High performance concrete (HPC) exceeds the properties and constructability of normal concrete. Micro silica or silica fume is very fine non crystalline material. Silica fume is produced in electric arc furnace as a byproduct of the production of elemental silicons or alloys containing silicon. IT is usually a grey colored powder somewhat similar to Portland or some fly ashes silica fume is generally categorized as a supplementary cementious material In our experiment we are using micro silica as an artificial pozzolans. We are adding 0%, 5%, 10%, 15% and 20% by wt of cement in concrete. HPC are made with carefully selected high quality ingredients and optimized mixture designs. Super Plasticizers are usually used to make these concretes fluid and workable. HPC almost always has a higher strength than normal concrete
