Concrete Canvas: A Multifaceted Construction Material

Cement concrete is a most used construction material, due to its enormous demand worldwide in the construction sector. Concrete serves many purposes in different adverse conditions, there are many advantages but there is one limitation that is concrete is not flexible. Concrete Canvas brought a revolutionary change in the construction materials called Geosynthetic Cementitious Composite Mats (GCCMs) which as many applications and used as an alternative to conventional concrete. It is a flexible, concrete canvas that gets hardens on hydration to form a thin, durable, waterproof and low-carbon concrete layer. Concrete Canvas may find its tremendous scope in the Construction sector as fire resistance and water proofing material. The concrete canvas has a self healing property thereby adds good benefit to the life of material and economically because of its zero percent repairs maintenance. Even though if the concrete canvas gets damaged after a period of time, it gets self healed with the contact of water which helps in the hydration process. This paper mainly focuses on the case study done on the applicability of concrete canvas for fire resistant, Water proof and bulletproofing with the help of AP State Police and to explore different applications in Construction sector as well as Defense sector.</jats:p

Strength Characteristics and Corrosion of Glass Fibre Reinforced Concrete Column Exposed in Sea Water Environmental Condition

This paper highlights the investigation on the strength and corrosion study of glass fibre reinforced concrete (GFRP) column in sea water environmental condition. Specimen of size 600 mm length x 150 mm wide x 300 mm deep columns were cast. Totally 8 columns were cast. Out of which, 4 columns were cured using potable water and 4 columns were cured using in artificial sea water. Among 8 reinforced concrete columns, two concrete columns were used, as the reference column containing steel rods both in longitudinal and horizontal ties and were cured both in potable and artificial sea water. For the corrosion study, 2 concrete columns reinforced by GFRP bars in the longitudinal direction and steel rods as horizontal ties and were cured using artificial sea water. Rebound hammer and Ultrasonic Pulse Velocity tests were performed on columns to evaluate the strength characteristics at the end of 7, 14, 28, 56 and 90 days of curing. The results will also be validated using destructive methods. Corrosion study was also performed by single Cu-CuSo4 Half-Cell equipment. Based on the observation, it was found that the compressive strength in artificial sea water curing exhibited better performance than in potable water curing.</jats:p
