Mechanical And Durability Studies Using Polypropylene Fiber and Quarry Dust In Concrete

2024-08-23T17:03:21+0530

As conventional concrete has become pricey and scarce River sand, which is one of the
constituents used in the output of due to depletion of river bed. Quarry dust is a waste incur
during quarrying process. In the present study, the use of quarry dust as the fine aggregate
drop-off the cost of concrete production in terms of the complete replacement for natural
river sand. In this research the experimental study is carried out the
influenceof0%to100%replacementofsandwithquarrydust.The weakness in tension can be get
over by the use of conventional rod reinforcement and to some extent by the inclusion of a
adequate volume of certain fibers; various proportions of polypropylene fiber are taken to
check the properties of concrete. The objective of this is to increase the strength of concrete,
Mechanical and durability studies using polypropylene fiber and quarry dust. To use the
industrial waste quarry dust as replacement of fine aggregate

Smart Village” is that modern energy access acts as a catalyst for development in education ,
health, security, productive enterprise, environment that in turns support further
improvement in energy access. In this report we focuses on improved resource use efficiency,
local self-governance, access to assure basic amenities and responsible individual and
community behavior to build happy society. We making smart village by taking smart
decisions using smart technologies and services.

Influence of GGBS in Alkali Activated Slag and Fly Ash Based Geopolymer Concrete

2024-08-23T17:06:15+0530

This paper research about experimental study and behavior of Geopolymer concrete in the
various aspects such as strength and durability. Now a days pollution is a main factor to
cause many health diseases especially the air and water pollution is a vital one. The high
production of electric power gives more satisfaction for human being to live in the world but
in another way it produces more pollution in the form of fly ash. So to reduce the air
pollution we can reuse as a pozzolanic material for the concrete. Geopolymer concrete is an
absence of cement for making concrete which is investigate by comparing the strength and
durability with the conventional concrete of grade M40.one of the most important ingredients
in normal concrete is Portland cement but in the Geopolymer concrete Alkali Activated Slag
and Fly ash. The alkali activators are attained by combination of Sodium Hydroxide (NaOH)
and Sodium Silicate in (Na2SiO3) the ratio of 2.5 and of molarities 12M and 16M.Durability
test conducted was Chloride Attack test. The tests are conducted for Oven dry curing and
open air curing concrete as Split tensile, flexural strength tests at 28th day. Compressive
strength tests are carried out on 7, 14, 28 and 56 days, Durability test on 56th day. AAS and
FA based geopolymer concrete has great potential for utilization in construction field as it is
Eco-Friendly.

Analysis of Composite Beam by Finite Element Method

2024-08-23T16:52:31+0530

An analysis of the Composite beam placing emphasis on shear deformation effects is done by
using beam theories and software ANSYS workbench. Results using two dimensional plate
theories are presented to calculate stresses in the beams. Two dimensional plate theories are
Classical laminated plate theory, first order Shear deformation theory, third order Shear
deformation theory and Euler-Bernoulli theory. Unit axial load over the junction of two
layers is placed and analyzed. For manual analysis transverse shear stresses are obtained
directly from the use of constitutive relations with good accuracy. Principle of virtual work is
used for obtaining boundary conditions and governing differential equations. A hollow
circular composite beam is analyzed for two different aspect ratios. The concept that is used
in this paper is that Graphite epoxy layer or laminate is sandwiched between two Steel layers
or laminates, and all the properties of both the materials are taken into consideration
wherever applicable.
