The project report entitled “study the strength of M30 grade concrete using Glass fibre, synthetic and Natural fibre”. The main objective of the study is to analyse the strength of M30 grade concrete using glass. Synthetic and natural fibre. In this process of identifying the strength of the used concrete we can conclude the best material to be mixed with for better long-lasting strength. These details of concrete and fibre are collected by a few articles and through some experiments Glass, jute, nylon fibres are taken in the ratio of 0.5% ,1.5% ,2.5 %. Complast sp420 is used for water reducing. Mixing of fibres in concrete helps in increasing 50% of strength then conventional concrete with better increase of mechanical properties. We are casting cubes for compression and cylinders for tensile strength. Chairs and tables are used for better understanding. This study focuses on evaluating the strength characteristics of M30 grade concrete incorporating three distinct types of fibres: glass, synthetic, and natural. The investigation includes a comprehensive analysis of the mechanical properties of these fibre-reinforced concrete mixes. Various tests such as compressive strength, and split tensile strength are conducted to assess the performance and effectiveness of each type of fibre. The research methodology involves the preparation of M30 grade concrete specimens with varying fibre content for each type. The concrete mixes are cured and subjected to a series of standard tests to evaluate their strength and durability. The study aims to understand the influence of glass, synthetic, and natural fibres on the overall performance of M30 grade concrete and to identify the optimal fibre dosage for enhanced structural properties. Results obtained from the experimental tests are analysed and compared to ascertain the impact of each fibre type on the concrete\'s strength characteristics. The findings aim to contribute valuable insights to the field of concrete technology, providing a basis for informed decision-making in the selection and application of fibres to improve the performance of M30 grade concrete in structural applications. Through experiments with considerable apparatus, process and ratios we can conclude the result
I. INTRODUCTION
Fibre Reinforced Concrete (FRC) is a composite material made up of fibrous material that adds structural strength and integrity. The term FRC is defined by ACI as concrete, incorporated with dispersed randomly oriented fibres. Since concrete is a significantly brittle material and exhibits a very poor tensile strength, it cracks easily and results in freeze and thaw damage, scaling, discoloration, and also steel corrosion. Therefore, to sort out these issues, fibres are added to concrete to control the cracks and crack growth . Commonly, various synthetic and natural fibres are used in concrete to control cracking and its propagation caused by plastic and drying shrinkage. The papers published in the early 1960s brought FRC to the notice of academic and industry research scientists all around the world . At that time there was a significant sense of discovery and enthusiasm that FRC can promise a great future development for Portland cement-based composite material. Since then multiple investigations have been made by the researchers into the development of FRC by incorporating various fibres like glass, nylon and jute fibres. This paper intended to present the effects of adding various types of fibres in concrete.

III. TYPES OF FIBRES USED
IV. COMPRESSIVE STRENGTH
Compressive strength refers to the maximum load per unit area that a material can withstand under compression before it fails or fractures. In the context of concrete, compressive strength is a critical parameter as it indicates the ability of the concrete to withstand applied loads or pressure without undergoing significant deformation or failure. It is typically measured in megapascals (MPa) or pounds per square inch (psi) and is determined by conducting standardized compression tests on concrete specimens.
The compressive strength of concrete is influenced by various factors including the mix proportions, curing conditions, age of the concrete, and presence of any additives or reinforcements like fibers.
V. SLUMP TEST
The slump test is a standard test in civil engineering and construction to measure the consistency of freshly mixed concrete before it sets. It involves filling a cone-shaped mold with concrete, compacting it, then removing the mold and measuring the settlement, or "slump," of the concrete. This test helps ensure the concrete has the desired workability and strength for its intended use.
VII. ACKNOWLEDGMENT
I am profoundly thankful to Mr. G. Tirupati Naidu Head of the Department of Civil Engineering, Dr.Lankapalli Bullayya College of Engineering, Visakhapatnam, India, who has served as my mentor and guide, advising me on how to accomplish my goals.
From the results and discussions, a few summaries can be drawn. The workability decreased with the increasing percentage of fibers (glass,jute,nylon). • The workability of FRC either with WHSF or SBF decreased with the • The compressive strength of FRC with 0.2% addition of WHSF and 0.5% The addition of raw Fibres shows an predominant increase in the compressive strength of the cube and cylinder when compared to conventional concrete. It observed that the compressive strength of the conventional concrete is 18N/mm2 for 7days and 39N/mm2 for 28 days. In Glass Fiber, The addition of glass fiber at 0.5%,1.5%,2.5% for concrete.it has been observed that the workability of concrete increased at 2.5% with the addition of glass fiber. The increase in compressive strength for M30 grade of concrete at 7and 28days are observed to be more at 2.5%. As the fiber content was increased above 2.5% the compressive strength gets reduced. Excessive addition of fiber leads to poor workability. In Jute Fiber, The addition of jute fiber at 0.5%,1.5%,2.5% for concrete.it has been observed that the workability of concrete increased at 1.5% with the addition of glass fiber. The increase in compressive strength for M30 grade of concrete at 7and 28days are observed to be more at 1.5%. As the fiber content was increased above 2.5% the compressive strength gets reduced. Excessive addition of fiber leads to poor workability. In Nylon Fiber, The addition of nylon fiber at 0.5%,1.5%,2.5% for concrete.it has been observed that the workability of concrete increased at 1.5% with the addition of s fiber. The increase in compressive strength for M30 grade of concrete at 7and 28days are observed to be more at 1.5%. As the fiber content was increased above 2.5% the compressive strength gets reduced. Excessive addition of fiber leads to poor workability.
