The document investigates using iron slag as a reinforcement material to improve the properties of soil, including strength and permeability. Various tests are conducted on soil samples with 3%, 6%, and 9% iron slag content, such as compaction testing, shear strength testing, and permeability testing. The results indicate that adding 3% iron slag provides benefits like increased strength and reduced permeability without significantly impacting other properties, making it a suitable proportion for soil reinforcement.
INVESTIGATION ON FLY ASH AS A PARTIAL CEMENT REPLACEMENT IN CONCRETESk Md Nayar
The use of Portland cement in concrete construction is under critical review due to high
amount of carbon dioxide gas released to the atmosphere during the production of cement. In
recent years, attempts to increase the utilization of fly ash to partially replace the use of Portland
cement in concrete are gathering momentum. Most of this by-product material is currently
dumped in landfills, creating a threat to the environment.
Fly ash based concrete is a ‘new’ material that does not need the presence of Portland
cement as a binder. Instead, the source of materials such as fly ash, that are rich in Silicon (Si)
and Aluminium (Al), are activated by alkaline liquids to produce the binder.
This project reports the details of development of the process of making fly ash-based
concrete. Due to the lack of knowledge and know-how of making of fly ash based concrete in the
published literature, this study adopted a rigorous trial and error process to develop the
technology of making, and to identify the salient parameters affecting the properties of fresh and
hardened concrete. As far as possible, the technology that is currently in use to manufacture and
testing of ordinary Portland cement concrete were used.
Fly ash was chosen as the basic material to be activated by the geopolimerization process
to be the concrete binder, to totally replace the use of Portland cement. The binder is the only
difference to the ordinary Portland cement concrete. To activate the Silicon and Aluminium
content in fly ash, a combination of sodium hydroxide solution and sodium silicate solution was
used.
Manufacturing process comprising material preparation, mixing, placing, compaction and
curing is reported in the thesis. Napthalene-based superplasticiser was found to be useful to
improve the workability of fresh fly ash-based concrete, as well as the addition of extra water.
The main parameters affecting the compressive strength of hardened fly ash-based concrete are
the curing temperature and curing time, The molar H2O-to-Na2O ratio, and mixing time.
Fresh fly ash-based concrete has been able to remain workable up to at least 120 minutes
without any sign of setting and without any degradation in the compressive strength. Providing a
rest period for fresh concrete after casting before the start of curing up to five days increased the
compressive strength of hardened concrete.
The elastic properties of hardened fly ash-based concrete, i,e. the modulus of elasticity,
the Poisson’s ratio, and the indirect tensile strength, are similar to those of ordinary Portland
cement concrete. The stress-strain relations of fly ash-based concrete fit well with the expression
developed for ordinary Portland cement concrete.

COMPARISON OF SUBGRADE SOIL STRENGTH USING LIME & COST ANALYSISSk Md Nayar
Soil stabilization can be explained as the alteration of the soil properties by chemical or physical means in order to enhance the engineering quality of the soil. The main objectives of the soil stabilization is to increase the bearing capacity of the soil, its resistance to weathering process and soil permeability. The long-term performance of any construction project depends on the soundness of the underlying soils. Unstable soils can create significant problems for pavements or structures, Therefore soil stabilization techniques are necessary to ensure the good stability of soil so that it can successfully sustain the load of the superstructure especially in case of soil which are highly active, also it saves a lot of time and millions of money when compared to the method of cutting out and replacing the unstable soil. This project report deals with the complete analysis of the improvement of soil properties and its stabilization using lime.
The need for efficient and better construction methods and materials is increasing day by day due to the rapid urbanization taking place around the globe at the same time it is our responsibility to make sure that the application of materials involved in the construction does not create adverse environmental impacts. In this research an attempt to review the optimization of the material usage of a hollow core in Reinforced concrete (RC) flexural members in the zone of tension. This shall facilitate the reduction of the dead loads which is an important factor with respect to seismic effect on structures. This paper studies the research works carried out on RC hollow beams in order to understand the flexural behaviour compared with the conventional solid beams.

Experimental study on partial repalcement of fine aggregate with construction...eSAT Journals
Abstract The construction industry has gained very fast growth in recent decades due to the increase in population, increase in
industrialization and also introduction of new infrastructure projects. These resulted in the growth of construction industry
drastically, which leads to a huge demand for construction materials and also in generation of huge amount of construction
waste. The present work aims at finding the optimum concrete mixture encompassing of cement mortar and brick bat debris as a
substitute for fine aggregate. Also the basic properties of cement mortar debris and brick bat debris as fine aggregate was
studied and it is compared with the traditional fine aggregate. The effect of cement mortar debris and brickbat debris as fine
aggregate in concrete for different proportions on strength was recorded at the curing age of 7, 14 and 28 days. All the data are
tabulated andcompared. It was observed that particular proportions of cement mortar debris and brickbat debris displayed
enhancing effect onthe compressive strength.

Strength behaviour of foundry sand on modified high strength concreteeSAT Journals
Abstract Metal foundries use a large amount of sand as part of the metal casting process. Foundry industries generally recycle and reuse the used foundry sand many times in casting process. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as "foundry waste sand." Like many waste products, foundry sand has beneficial applications to other industries. A mixture of silica sand coated with a thin film of burnt carbon and residual binder with traces of dust is termed as foundry sand. From the previous available literature it was found that replacement of sand by foundry sand by certain initial percentages gives a marginal increase in hardened properties of normal strength concrete. In the present work, fine aggregate is replaced by foundry sand with percentages and tests were performed for hardened properties of modified high strength concrete for all replacement levels.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
