Fibre Reinforced Self Compacting Concrete using Steel & Basalt Fibres

Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight. The hardened concrete is dense, homogenous and has the same engineering properties and durability as traditional vibrated concrete. The objective is to find out the optimum fresh properties such as T50cm, Flow spread, L-Box and V-Funnel time and hardened properties such as Compressive, Flexural and Split Tensile Strength at ages of 7 and 28 days of SCC cubes, beams and cylinders reinforced with steel and basalt fibre.

Pollution Cleaning Tower

The objective of the tower is to remove all 97 types of Air Borne Pollutants at CADR of 8-10 lakhs cubic meters of air an hour and whose range is up to 10 Km2 through which it will be capable of removing the particles of sizes up to 0.1µm and PM2.5 & PM10 from the air by which it can able to clean the air up to 99.90%.

Geopolymer Concrete- An Eco-Friendly Concrete

Cement production is highly energy-intensive and release a large volume of carbon dioxide. Production of 1-tonne cement leads to the emission of 0.8-1 tonne carbon dioxide. It has been observed that fly ash with alkaline activator (NaOH + Na2SiO3) can produce binding material same as cement + water. On the other hand, coal-burning power generation plants produce large quantities of fly ash which are considered as waste and dumped into landfills. Concrete in which cement is completely/partially replaced by this binding material is named as Geopolymer concrete. The objective is to compare the compressive strength of a geopolymer concrete under the various types of curing method.
