Investigation on Polypropylene Fiber Reinforced Concrete with Alccofine-1203

Abstract

In this study, cement containing Alccofine-1203, which is finer than cement and gives the concrete structure greater strength and endurance. Polypropylene fibers are used to enhance strength properties of concrete. Fibers made of polypropylene are added at rates of 0, 1.5, and 2.0%. Cement that has been mixed with several amounts of Alccofine-1203, including 5, 10, 7.5, and 12.5%. For concrete that has set, strength tests are performed after 28, 56 and 90 days. To evaluate the mechanical characteristics of concrete, destructive tests are performed on the dried specimens.

Introduction

I. INTRODUCTION

Concrete is a composite material made of coarse aggregate joined by fluid cement that gradually becomes harder. The most common types of concrete are those manufactured using other hydraulic cements or lime-based concretes like Portland cement concrete. However, asphalt concrete, which uses bitumen as the cement, is also a type of concrete that is used for road surfaces. Polymer concretes, which employ polymers as the cement, are also occasionally used. When the aggregate, dry cement, and water are combined to make Portland cement concrete (and other hydraulic cement concretes), they create a fluid mass that is simple to shape.

The primary production materials today are cement-based, and this significance will most likely remain in the future. They must compete with other construction materials in addition to plastic, metal, and wood while dealing with challenges related to production, the economy, quality, and the environment. Durable concrete will maintain its quality and usability even when exposed to the elements. Fine mineral powders such as fly ash, ground-granulated blast furnace slag, limestone, silica fume, and aluminium fine should be used to make cement-based ingredients for concrete. When producing concrete, these cement-based components are combined with cement in the mixer.The primary production materials today are cement-based, and this significance will most likely remain in the future.

This paper provides details regarding the behaviour of alccofine in concrete. Alccofine is a micro-fine material produced in India that contains particles that are even finer than those found in cement, fly ash, silica, and many other cement-based products. Because of its optimum particle size distribution, this material has a unique ability to improve concrete's performance at all stages. Chemical reactions between the cement, water, and other chemicals create a rigid matrix that binds all the components into a long-lasting substance that resembles stone and has a variety of functions. Alccofine is a brand-new generation of micro-fine material produced in India that has significantly smaller particles than other hydraulic materials like cement, fly ash, silica, etc.

II. OBJECTIVES

To maximize the percentage of partial Alcofine-1203 substitution in cement.

III. MATERIALS

A. Alccofine-1203

Compared to cement, fly ash, and other materials of a similar kind, Alccofine 1203 is a new generation micro-   fine material. This experiment used the mineral ingredient Alccofine from Ambuja Cements Ltd. Alcofine 1203 is an additional cementitious component that can take the place of silica fume in high-performance concrete. It is constructed using supplies utilised in the iron ore industry. Alccofine has a higher percentage of alumina and silica content in its chemical composition. Concrete can function more effectively in both the fresh and hardened stages thanks to certain characteristics of it. It can be used as a good substitute for silica fume. The strength and longevity of concrete of all ages are improved by the use of Alccofine 1203 as a cement substitute.

B. Polypropylene Fibers

A synthetic fibre made from 85% propylene and utilised in a number of applications, polypropylene fibre is also known as polypropylene or PP. Although there are many various sectors that use it, the production of carpet yarns is one of the most common. For instance, this fibre is used to make the majority of affordable carpets for light residential use. The fibre is lightweight, thermoplastic, robust, and resistant to mildew and several chemicals.

C. Concrete Mix Design

The mix design conducted in the laboratory conditions by trial and error and confirming to IS: 10262-2009 for M40 grade of concrete. The weight ratio of mix proportion is 1:1.28:2.41 with water cement ratio 0.4.
