Behaviour of Concrete with Waste Glass Fiber Powder
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
Glass is basically used in the industries, for decoration purpose in building’s construction and also in our daily use items such as bottle, container and utensils etc. After the life span or use it is dumped anywhere as a waste that causes a disposal problem to environment because of its properties of non-biodegradable. Most of the glass waste are not being recycled and directly disposes to landfills. If this waste converted into aggregate after the recycling or grinding will results into the solution of disposal problem and reduces the supply of raw materials for construction. Glass can cause deleterious alkali- silica reaction problems because of alkaline environment. Due to this, it can be ground into a fine powder and used as a pozzolonic material in concrete. In laboratory experiments it can suppress the alkali-reactivity of coarser glass particles, as well as that of natural reactive aggregates. It undergoes beneficial pozzolonic reactions in the concrete and could replace up to 30% of cement in some concrete mixes with satisfactory strength development. There is a strong need in concrete industry to replace the raw materials with economic one. Most of the researcher have done experiments on the concrete by replacing constituents with waste glass powder or aggregate. After their conclusion it was found that there is strength regression and expansion in concrete mix if waste glass aggregate replaced with coarse aggregate. This was due alkali reactions. And strength loss was also found in fine aggregate substitution. The present study on waste glass powder as a replacement of cement to assess the pozzolanic activity of fine glass powder in concrete. A number of test were conducted on specimens to study the effect of 10% ,20% and 30% replacement of cement by waste glass powder. The compressive strength, split tensile strength and the flexural strength test were conducted for the mixes at the curing age of 7 days and 28 days. All the results of experiments were compared with the normal concrete mix’s results. Waste glass powder in partial replacement of cement in concrete can be prove beneficial to disposal problem of glass waste and the need of economic raw material to the concrete industry.
