 Abstract

The purpose of this experiment was to examine the capabilities of bacterial concrete for building. To make concrete stronger than regular concrete and to increase the qualities of concrete, a bacterial called BACILLUS SUBTILIS (together with its nutrition) is injected. The project is designed to investigate evaluate cube specimens compressive strength, know the optimal number of bacteria to use, and research the characteristics of cracks in the specimens by adding the urease, gram-positive Bacillus Subtilis (spore forming bacteria), as well as facultative aerobic. Mechanism: When there is oxidation and moist present, bacteria transfer the calcium found in concrete into lime. We deduced from the abovementioned method that adding bacillus species to concrete boosts its strength and gives it the ability to self-heal cracks

In the present work, Kadukkai (Terminalia Chebula) isused as natural admixture and examined its effect on the properties of conventional concrete and fly ash blended concrete. In detailed, the effect of Terminalia Chebula on the properties such as compressive strength and split tensile strength of fly ash blended concrete and conventional concrete was investigated. The consistency increased with increase in dosage of natural admixture up to 2% for fly ash blended binders. Various percentages of fly ash such as 10, 20, 30, 40 and 50% and Kadukkai (Terminalia Chebula) powder of 0.25, 0.5, 0.75 and 1.0% are investigated. The mechanical properties of the conventional concrete as well as fly ash blended concrete are improved by addition of natural admixture at an optimum dosage of 0.75%. On the other hand, the consistency of fly ash blended concrete is increases with increased dosage of natural admixture up to 2%. It has been observed that with the optimum dosage of natural admixture, the fly ash blended concrete achieved the desired strength at 28 days of curing. In a nutshell, the concrete mixture containing0.75% of natural admixture and 30% of fly ash for M 25 grade of concrete

 Abstract

Industrialization and urbanization has led to depletion of high quality construction materials. The cost of construction materials is increasing significantly, so are their availability. So alternate construction materials are to be found and exploited. The material Phosphogypsum and fly ash has been found to have certain properties which can be useful in the construction. Phosphogypsum is the primary byproduct of the wet-acid process for producing phosphoric acid from phosphate roc and fly ash is the by-product of coal. The aim of the project is to develop a sustainable concrete with improved strength, durability and having less maintenance by utilizing Phosphogypsum and fly ash. Mechanical strength for compressive strength, split tensile strength and flexural strength were conducted to find the optimum usage of alternative materials with proportions of 5%, 10% and 15% of total weight of concrete and durability tests of sulphate , chloride resistance and corrosion test were performed. From the studies, it is concluded that long term strength and durability has increased when fly ash concrete is modified by partially replacing cement with 10% of phosphogypsum.The phosphogypsum increases the workability of the concrete due to the combined lubricating effect of fly ash and phosphogypsum. The strength properties are similar to the addition of fly ash in concrete.From durability studies of rapid chloride permeability, with the inclusion of fly ash, chloride ingress capacity of concrete is decreased. Pore refinement and grain refinement due to reaction between fly ash and liberated lime improves impermeability. The reduction in permeability of concrete is mainly due to filling of the pores and voids with calcium carbonate precipitation.

 Abstract

Since the start of Bitcoin in 2008, blockchain technology emerged as the next revolutionary technology. Though blockchain started as a core technology of Bitcoin, its use cases are expanding to many other areas including finances, the Internet of Things (IoT), security, and many more. Currently, many private and public sectors are diving into the technology. The rapid use of blockchain technology motivates to put an eye on the field of IoT. In this paper, we will study the implementation of blockchain for IoT to enhance its capabilities of IoT. Using this combination we can create many transformations across several industries, paving the way for new business models and novel, distributed applications.

 Abstract

There was a severe scarcity of river sand, which was ideal for a new study area. The depletion of river sand and the necessity for scientific management and use of the available resource have been studied. Foundry sand can be used as a partial or complete substitute for fine aggregates, as well as a supplemental addition to achieving various concrete qualities. By weight, Micro Silica was used in place of cement, and waste foundry sand was used in lieu of fine aggregate. At the ages of 28, 56, and 90 days, compressive and split tensile strength tests were performed. At 15% foundry sand replenishment, the maximum strength was obtained. When compared to ordinary cement concrete, blended concrete with micro silica has been shown to be more effective. Non destructive test was carried out to evaluate the strength property

 Abstract

Concrete is used worldwide and hence the usage of its constituents plays a major role in determining its health. The vast majority of it contains fine aggregate. River sand, which is readily available, is commonly used as a fine total in many countries. The increased demand for concrete has led this common sand asset to deteriorate. On the one hand, the abundant consumption of river sand has had incredibly clear natural impacts. Essentially, the amount of MSand added by weight was 10, 20, 30 and 40% of the fine total substitution in concrete, respectively. By adding bacterial into the concrete performed well in durability and 30% of MSand showed better performance towards strength for M20 and M40 grade of concrete at 28, 56 and 90 days with UPV also

 Abstract

Dhaka, Bikrampur was the centre of cultural activities in East Bengal during Mughal period. Calcutta was born much later, during colonial times. In the British rule, Calcutta became the centre of Bengals Socio-economic life. However, the notable cultural differences between the people of East Bengal and West Bengal were prominent by this time. In that time the game of football was more popular among the people of Calcutta than others sports. During that time various public schools were established in East Bengal, specially in Dhaka and Bikrampur, where a considerable progress of western sports could be observed. As a result, football soon took a special place in public sphere of Dhaka. But even though the students of East Bengal gradually mastered the game, it was not easy to pursue their football talents in Calcutta maidans. Meanwhile, several football clubs were born in the Dhaka city. As a result, gradually football club culture spread in to other places of East Bengal such as Chittagong, Tajhat, Mynmensingh etc. Not only football clubs were formed in East Bengal but also important football tournaments and League were constituted.
