Abstract Manufactured sand and natural sand in concrete with a partial substitute for the fresh and hardened properties of the water-cement ratio, the outcome of the investigation. M30 of concrete mix design part was done in accordance with the IS Code (that is, 10262:2000). Concrete cube, prism and cylinder respectively compressive, flexural strength and split-tensile strength were tested to evaluate. Workability was measured as far as the reason for compaction and slump. This M-sand in concrete can be utilized as a practical contrasting option to normal sand. 60% of M-sand have good strength with replacement. This work puts forward the sand applications (manufactured) as practical advancement in India. In addition, steel fiber is a good idea to use a sequence of concrete strength and workability. Are carried out using a number of tests, including tests of workability, compressive test, tensile test and flexural test. Fly ash use in concrete, cement consumption reduction and reduced permeability is required as benefits. Fly ash use in concrete leads to an improvement in the original strength, but there is a long-term increase in strength.

INTRODUCTION

Concrete reinforcement often associated with the use of cement, fine aggregate, steel. Portland cement and fine aggregate, is one of the building material widely used, because the sand led to a shortage of river sand, increase in the interest of the government in building materials and restrictions on quarrying. Portland cement was turned more to the location to CO2. The investigation should be used in fly ash an alternative material for cement and m sand for fine aggregate respectively. Increase the tensile strength of concrete the method of introduction of fibers used in reinforced concrete is being realistic. These fibers prevent the propagation of the act to crack arrestors and cracks. These fibers are consistent, which is distributed randomly arranged. This concrete is named as Fiber reinforced concrete.

Concrete matrix to add to the fiber of the main reasons is to improve the tactile response post cracking its energy absorption capacity and improve clear ductility, and crack resistant II. EXPERIMENTAL DETAILS Methodology: In this research work is carried out to determine strength properties concrete obtained by the use of m sand, fly ash reinforced by steel fibers. Cement is replaced by fly ash in varying percentage, fine aggregate is replaced by m sand by 60% and steel fiber is used for reinforcement. IS code procedure is followed to carry out the test. The tests are carried out on plain concrete and also on modified concrete in which cement is replaced by the fly ash in various percentage from (0%,10%,20%,30%,40%,and 50%).

Before arriving to final conclusion on both i.e. conventional and also on modified concrete the comparative study is done.

The following methodology is adopted for the proposed work 1) Collection of articles and journals to understand and get the idea on the research work conducted on subject of work.

2) The properties of materials such as cement ,fly ash, natural sand , M sand , coarse aggregate and fiber to be studies by conducting the tests as per BIS 3) To obtain the mix proportion for M30 Grade concrete by IS method 10260 : 2009 4) Calculate the mix proportion of various material such as cement replaced by fly ash (0%, 10%, 20%, 30%, 40%, and 50%), natural sand with M sand (60%), coarse aggregate with fiber (1%).

5) The concrete specimens are prepared such as cube for compression strength, cylinders for split-tensile strength and prism for flexural strengths and also cubes for acid test.

6) The curing of specimens for 7 days and 28days.

7) The compression strength, split-tensile test and flexural strengths are evaluated.

8) The durability of M 30 grade with replacement of fly ash and M Sand with fiber replacement concrete by 5% concentration of sulphuric acid 9) Analysis is carried out with modified concrete and conventional concrete.

Materials: Fibers increase the structural features of the building materials since past times it was utilized in the construction. Horse hair was utilized to strengthen the concrete. Metal fiber is one of the most commonly utilized fiber Aspect ratio is ratio of length to diameter of the fiber, the concrete strength depends on the strength and toughness increases to trend above 30 -150 aspect ratio. Inspections can be found from the outside that can get good results on steel fiber in a range around 80. We view the 50 aspect ratio (length 60 mm and a dia of 0.75 mm) with crimped iron fiber. Class C-fly ash remains has pozzolanic properties. In this test, low calcium, class c dry fly powder. Utilizing a fly ash (pozzolanic) expends calcium hydroxide (CH: the frail connection) and other free hydroxides (OH) to frame more calcium silicate hydrate (CSH).fly ash of class c having property similar to cement ,its being used as substation to cement with certain percent. Fine aggregate as one of major part of concrete needs to be obtained from natural sources, manufactured sand (4.75mm to 75 micron (0.2 to 0.003 in)) is utilized for halfway substitution to regular sand .Crushed rock in the quarry to produce a total sum of the course and fine aggregate construction materials. M sand is one of good material for the replacement of fine aggregate and it have same properties as of fine aggregate which can be obtained from cone crushers, impact crushers, roll crushers, crushing rollers which causing unperishable effect on environment, m sand being used as alternative obtained from industry is ecofriendly and economic.

Mix Proportioning: Fly ash was replaced to cement in the varying range of 10%,20,%30%,40%,50% . The fine aggregate was replaced by m sand by 60% and steel fiber reinforcement was kept constant to 1%, consideration of this mix proportion for m30 obtained is as follows: Water 0.41

Cement 1

Fine aggregate 1.3

Coarse aggregate 2.26

Mixing and Casting: First the course aggregate ,fine aggregate, manufactured sand, fly ash, cement, steel fibers ,are weighed as per mix design and were dry mixed for 2-4 minutes. Water as per the design is poured on dry mix and then mixed again to obtain well wet mix. The concrete is poured in the moulds and then compacted with tamping rod/vibrating table machine. Then the top surface is well finished. The sizes of the moulds used were cube (150mm x150mm x150mm), cylinder - (150mm dia and 300 mm height), prism - (500 mm x 100 mm x 100 mm).

Curing: The moulds after casting are placed in room temperature and were then demoulded after 24 hours and were placed in curing tank for the period of 7days and 28days.
