Robo sand is one of the most used among such materials to substitute river sand, which can be used as an replacement to fine aggregate in concrete. In the present investigation workability and strength of concrete was evaluated by replacement of natural sand by robo sand in proportions of 0%, 30%, 50%, and 60% is studied for M25 grade concrete cubes, cylinders and beams. Slump cone method is taken for finding workability. For strength parameters for each grade of concrete Cubes, Cylinders and beams were casted and tested at the age of 7,14 and 28 days. In this present experimental study on concrete having grades of M25 are prepared by replacing natural sand by Robo sand. Concrete specimens were tested for evaluation of compressive strength and water absorption. Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. Concrete containing robo sand ,WFS. Steel scrap is a concrete combinations of performance and uniformity specifications that cannot be always achieved routinely by using conventional constituents and normal mixing. This leads to examine the effect what changes can improve the performance of the concrete. On the other side, cost of concrete is attributed to the cost of its ingredients which is scarce and expensive, this leading to usage of economically alternative materials in its production. This requirement is drawn the attention of investigators to explore new replacements of ingredients of concrete. The present paper focuses on investigating characteristics of M25 concrete with partial replacement sand with Waste foundry sand with the ROBO sand (crusher dust) having appropriate quantity of steel scrap. The cubes and cylinders are tested for both compressive and tensile strengths. It is found that by the partial replacement of cement with steel scrap and sand with ROBO sand and WFS improves the strength of the concrete substantially compared to normal mix concrete
KEYWORDS
By performing the research on various aspects of WFS with steel scrap and Robo sand and its potential applications in , concrete. The following conclusions are the result of this work: Compressive Strength is maximum at 50 % replacement of fine aggregate with robo sand, which is best at 28 days keeping values of steel scrap as 1.5% and WFS 30% Flexural Strength followed almost the same path with 50 % having highest strength with value of 5.78 MPs for M25 Concrete. Water Absorption values are maximum for 15 % as water absorbing power of robo sand is found to be high. Workability tends to decrease with increasing robo sand. The Changes in the results found in workability, mechanical strength, and durability may be due to differences in composition, fineness modulus, cementitious material, and replacement rate used. • The inclusion of robo sand with WFS and steel scrap results in material cost savings ranging from 20% to 30%. This will depend on the degree of substitution and the prices of materials in each country. In summary, while incorporating robo sand with WFS and steel scrap in concrete offers environmental sustainability issues remain in workability and strength, particularly at higher replacement levels. All the percentage of replacement was found to be good when compared to control concrete At the substitution of 50% robo sand for M 25 grade, from 7 days to 28 days the pace of increment in compression is of 34.3% and flexural is of 3.5% and tensile strength is of 3%. Strength increases by 20 to 25% by using robo sand in percentage of 0% 30% 50 % 60%.
