Abstract
An attempt was made to use the waste water from textile industry for construction purpose, so that the shortage in water can be greatly reduced and the waste water can be suitably disposed for safe guarding the environment. The basic properties of the treated and untreated water from the textile industry were tested and the results were found to be satisfactory such that it can be used for construction purposes. By using the waste water from the textile industry cubes, cylinders and beams were casted and tested for its mechanical properties (compressive strength, tensile strength, flexural strength etc) and the result was found to be satisfactory. Hence the experiment was continued on for durability studies where the corrosion attack was also studied. The results of other durability studies were found to be satisfactory. In this experimental study the results of specimen’s casted using treated and untreated textile water were compared with the specimens casted with potable water. Since there was some corrosion, admixtures were added to counter act the same and the results were found to be satisfactory.
Highlights
The term corrosion is defined as an act or process of gradual wearing away of a metal due to chemical or electrochemical reaction by its surroundings such that the metal is converted into an oxide, salt or some other compound
There was deterioration due to corrosion attack and to counteract the corrosion attack concare and calcium nitrate was added on trial and error basis and it was found that 2.5% concare and 2.0% calcium nitrate was found to be suitable
At the beginning, the loss of weight of reinforcement bar is less than 1.25% and at the end of 2.5 year the loss of weight of reinforcement bar is less than 2.25% for all the specimens cast using potable water, untreated textile Water and treated textile water
Summary
The term corrosion is defined as an act or process of gradual wearing away of a metal due to chemical or electrochemical reaction by its surroundings such that the metal is converted into an oxide, salt or some other compound. It indicates the deterioration and loss of material due to chemical attack. In this study comparison was made between specimens (cylinder) casted using treated textile effluent, untreated textile effluent and potable water. In addition cempatch-R coating was done on the reinforcement bar and the effect was studied. The specimens were tested after 28 days, 180 days, 1 year, 2 year and 2.5 years of curing
