An Experimental Study on Mechanical Properties of Concrete Paver Block with Partial Replacement of Cement with Metakaolin and Fine aggregate with Red Soil

Abstract

Even though it is the second most extensively used material in the world, after water, concrete is prone to a
broad variety of damages due to its low tensile strength. This is despite the fact that concrete is the second-most widely
used material in the world. There are a few characteristics that are connected to concrete that is produced by employing
Portland cement as the primary construction material. In terms of compression, it is fairly robust, but when it comes to
tension, it is insufficient, and it has a propensity to be brittle. Because of both of these shortcomings, its use has been
limited. There has been a significant increase in the demand for concrete as a material for construction. This is due to
the fact that concrete is a material that is both long-lasting and inexpensive, as well as the rapid growth of the building
industry and the expansion of the world's population. The use of concrete leads to a rise in the use of Portland cement,
which in turn leads to an increase in the amount of energy and emissions that are created. This cycle continues until the
quantity of energy and emissions increase. We came to the realization that metakaolin and red soil may be replaced in a
partial amount of up to 15-20% and 20%, respectively, in order to generate the same strength as traditional concrete.
This was the conclusion that we came to. Because of the considerable study that we conducted on the relevant literature,
we were able to arrive at this conclusion. During the course of our inquiry, we want to ascertain the suitable ratio of
metakaolin to red soil that ought to be used in the production of concrete in order to achieve the maximum possible
degree of strength. In order to identify the suitable amount of metakaolin and red soil that may be partially replaced in
the manufacture of concrete, we conducted a compressive test, a flexural strength test, and a split tensile strength test.
These kinds of tests were carried out in order to find the appropriate quantity. It has been determined that the best
possible result can be accomplished by partly substituting cement with metakaolin and red soil at a proportion ranging
from 20–5%. This is the conclusion that has been reached
