EXPERIMENTAL INVESTIGATION OF M30 GRADE USING NOVEL CRC WITH 16% AND GLASS FIBRE 5% AS A PARTIAL REPLACEMENT OF FINE AGGREGATE COMPARING WITH CONVENTIONAL MIX

Abstract

The primary study is to evaluate the differences between conventional concrete and M30 grade concrete with 16% Novel CRC as a replacement. Materials and Methods: Novel CRC, superplasticizer, cement (53 grade PPC), fine aggregate (sieve size 4.75mm), coarse aggregate (sieve size 20mm), and water. There are 2 groups that were considered. Group-! (control group/conventional concrete) and group-2 (experimental group/Novel CRC concrete). The First group has 18 samples and the Second group has 18 samples, Total samples ofN=29. G-power of0.8 with alpha and beta qualities of 0.05, and 0.2 with a confidence interval of 95% have been carried out, with independent sample T-Test value (p<0.05). Results: According to ANOV A using SPSS software, it is clearly identified that the compressive strength of conventional concrete is 32.08 N/mm2 The compressive strength of Novel CRC concrete is 31.6 N/mm2 . There is a significant difference and the significance value of O.OOO (p<0.05) and also standard deviations are 8. 7512 and 7.0012 respectively. Conclusion: The Novel CRC concrete with the superplasticizer has lesser compressive strength when compared to the normal concrete.

PREAMBLE TO THE DESCRIPTION
THE FIELD OF CONSTRUCTION (CONSTRUCTION INDUSTRY)
The invention pertains to innovative advancements in the construction, infrastructure(Paver
Blocks), specifically in the areas of Rigid Pavement and durability. By incorporating these materials,
we not only reduce reliance on traditional fine aggregate production, but also effectively utilize
Rubber waste products and Glass Fibre.·
BACKGROUND OF THE INVENTION
. In this modernized world, the growth of infrasf:!'Jcture plays a vital role for the development of the
country. The researchers are very unique, determined and mainly focusing on the effects which cause
environmental damages. As per the transparency Market Research the demand for crumb rubber for
concrete structures is highly inevitable. The demand is very high, because of the performance of road
construction materials to avoid cracks and increase their consistency. Construction cost and life span of.
road design is a challenging one for researchers to ensure the performance during driving conditions. Recent
years alteration of Asphalt to Crumb rubber improves the performance and creates barriers in cost effective
road construction. Increase in manufacture of Crumb rubber makes the market with high demand for crumb
rubber in construction materials. This rapid growth helps to alternate in various places, in which it can help
to lower costs by replacing more expensive virgin compounds. (Crumb Rubber Market). The process of
implementing the Crumb Rubber is highly inevitable in road Construction. (Hanson et al.).
SUMMARY OF THE INVENTION
Utilizing the CRC with Glass Fibre integrating with these materials, CRC and Glass Fibre (GF) as
replacements for fine aggregate we provide a sustainable and ecofriendly solution for modem Paver
Blocks and in pavements.


COMPLETE SPECIFICATION
Specifications
~ The material properties have played a significant role to meet the positive outcome. Physical
and chemical properties of the material such as ordinary Portland cement (OPC), fine
aggregates such as river sand (RS), CRC, Glass fibre and water were examined. The material
properties examined in the laboratory were specific gravity, water absorption, thickness, bulk
density, and crushing strength.
~ According to the standard provided in IS 12269: 2013 [Ill), this study, extensively utilized
OPC grade 53 having specific gravity 3.1 0. RS having specific gravity 2.60 and density 1686
kg/m3 was collected from native resources which satisfied the grading zone lli specifications
recommended by IS 383:2016 [112).
~ The binding of cement and other materials in this production is triggered by one of the most
essential components which is CRC. The strength of the pavement along with CRC is
achieved by the CTM. The accurate amount of water in the production of concrete will acquire
good workability and greater strength.
~ In this work, CRC and fine aggregates is replaced with 14-15% CRC and in addition 5%
Glass fiber is added to gain strength in Paver Blocks. Thus helps to with stand the pressure
from vehicle and Vulnerable road users.



DESCRIPTION
In our innovative approach to creating rigid pavements, we use a mortar mix with
superplasticizer. To enhance sustainability and strength, we replace 14-16% of the fine aggregate
with Glass fibre 05% into the mix. This blend not only promotes the recycling of CRC but also
improves the structural integrity of the Paver blocks and in rigid pavements. After preparation, the
Paver Blocks undergoes strength testing, with thorough analysis confirming their durability and
suitability for various purposes. The Paber Blocks is tested for their ability to withstand compressive
strength, tensile strength and abrasion test.



CLAIM
We Claim
I. Claim: Replacement of CRC and Glass fibre with respect to fine aggregate and the addition of
CRC enhances the structural integrity and durability of the Paver Blocks.
2. Claim: The ash helps in reducing of cracks forming in the Paver Blocks and m Rigid
pavements, which is crucial for maintaining their structural integrity over time.
3. Claim: By partially replacing fine aggregate, which is a significant source of C02 emissions,
with CRC, we reduce the overall carbon footprint of our product.
4. Claim: By incorporating these materials, we not only reduce reliance on traditional fine
aggregate production, but also effectively utilize Industrial Tyre waste products.
5. Claim: Despite their enhanced strength, the Paver Blocks remain lightweight and easy to
handle, making them practical for Cycling track, Walking and even in Service Lane.
6. Claim: Commercial implementation of results presented in this thesis may lead to low
construction cost and cleaner environment in rural areasas both the CRC and GF used are waste
products.
