Properties of Concrete with Acid IJTSRD


The main aim of this project is to see change in concrete by hydrochloric acid attack. It is well known that the concrete under acidic environment is deteriorated due to a chemical attack. For example, acid rain cause concrete unexpectedly short service life due to the damages for concrete cover. This paper presents the effect of Hydrochloric acid (HCl) on Blended Cement (Fly ash based (BC)) and Silica Fume Blended Cement(SFBC) and their concretes. The BC and SFBC and their concretes BCC and SFBCC produced with HCl dosage of 100, 150,300, 500 and 900 mg/l added in deionized water. In addition to this control specimens were prepared with deionized water (without HCl) for comparison. The setting times and compressive strength were evaluated for 28 and 90 days apart from studying Rapid chloride ion permeability. The results show that, as HCl concentration increases, there is retardation in initial and final setting of cements (BC and SFBC). The compressive strength of both BCC and SFBCC has come down with an increase in the concentration of HCl at both 28 and 90 days. Compressive strengths of BCC and SFBCC have decreased in the range of 2 to 19%, at 28 and 90 day age respectively, with an increase in HCl concentration, when compared with the control specimens. It was also observed that Chloride ion permeability has increased with an increase in the concentration of the acid. Though after this experiment we are considered that the effects of hydrochloric acid on concrete leads to slow n steady of concrete which make them weak and later on it demolishes completely.
