This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of …
T his study presents the use of plastic recycled aggregate as replacement of coarse aggregate f or production of concrete. They used forty-eight specimen and six beams/cylin ders casted from ...
Therefore, as a solution and to save environment the replacement of coarse aggregate in concrete is become essential. Theare various alternative materials for coarse aggregate such as wastes of plastic, glass rubber, coconut shell, construction waste, quarry dust etc. can be used as replcememnt of coarse aggregate in concrete.
results are compared with natural aggregates. Recycled aggregate reduces the impact of waste on environment. By using some percentage in construction sector, cost is saved, due to reduction 1.6 Anticipated Findings:- All the results of tests should satisfy the IS requirement of natural aggregates.
The past studies report that different alternative coarse aggregates such as steel slag [2][3][4][5][6][7][8 ... samples are analyzed and 25% replacement of natural aggregate with RCA gives ...
Experimental results indicated that such steel slag aggregate concrete achieved higher values of compressive, tensile and flexural strength and modulus of elasticity, compared to natural aggregate concrete.[1] 3. Shekarchi et al. conducted comprehensive researches on the utilization of steel slag as aggregate in concrete. They
The maximum size of the coarse aggregate was limited to 20mm. A sieve analysis. conforming to IS 383 1970 was carried out for fine aggregate and for various. proportions of sand replacement by slag. The concrete cubes (150mm X 150mm X. 150mm), concrete beams (100mm X100mm X 500mm) and concrete cylinders.
similar to coarse sand. This granulated slag is then dried and ground to a fine powder. The re-cycling of these slag's will become an important measure for the environmental protection. Iron and steel are basic materials that underpin modern civilization, and due to many years of research the slag that is generated as a by-
The scope of this study focuses on the use of two different types of industrial byproducts such as slags (FeNi and Electric Arc Furnace slag) combined with natural sand as concrete aggregates as well as the evaluation of their suitability on the final physicomechanical behavior of the produced concrete specimens. For this reason, twelve concrete …
The percentage replacement of sand by granulated copper slag where 0%, 5%, 10%, 15%, 20%, 30%, 40% and 50%. The compressive strength was observed to increase by about 35-40% and …
The results indicate that the use of copper slag in concrete increases the flexural strength of about 17% with that of control mixture. It is recommended that up to 40% of copper slag can be use as …
The Flakiness Index (FI) of the steel slag aggregate is markedly lower than those for the dolerite and quartzite aggregates ; A Polished Stone Value (PSV) of 63 for the steel slag aggregate indicates a high resistance to the surface of the aggregate polishing under the action of traffic. 15 STEEL SLAG AGGREGATE 16 STEEL SLAG AGGREGATE 17
Title: AGGREGATE 1 AGGREGATE Aggregates may be NATURAL or MANUFACTURED Natural aggregates sand, gravel, crushed rock Manufactured aggregates blast furnage slag Aggregates may also be …
It can be thus concluded that the replacement of natural aggregates by recycled equivalents is possible, but limited to 20% only, due to the inferior properties of RCA. This study examines the effect of RCA replacement and slag incorporation on the rheological, physical, transport, mechanical, and durability performance of pervious …
The effects of replacing limestone coarse aggregate by copper slag coarse aggregate on the compressive strength and splitting tensile strength are evaluated in this work. The use of copper slag aggregate compared to limestone aggregate resulted in a 28-day compressive strength increase of about 10–15 % and a splitting tensile strength ...
This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering. Three masonry wall panels of …
The trend of replacing natural sand with recycled fine aggregate (RFA) is gaining importance. ... Performance of high strength concrete made with copper slag as a fine aggregate. Construction and Building Materials, …
The maximum size of the coarse aggregate was limited to 20mm. A sieve analysis. conforming to IS 383 1970 was carried out for fine aggregate and for various. …
responses of above alternatives performed, and observed maximum value at 40% copper slag replacement which up to 36% increment. Keywords: Copper slag, design mix M25 grade concrete, M sand, natural sand, partial replacement, compressive strength responses 1. Introduction A huge amount of concrete is consumed by the construction …
An attempt has been made to study shear strength of RA concrete beams of M 20 grade with 25 and 50 % weight replacement of natural aggregate (NA) with recycled aggregate (RA) for different shear span to depth …
The use of copper slag (CS) as fine aggregate and partial substitute of cement for mortar preparationwas studied. Results showed an increase on compressive and flexural strength at 3, 7 and 28 ...
b) Fine Aggregates: The aggregates most of which pass through 4.75 mm IS sieve are termed as fine aggregates. The fine aggregate may be of following types: i) Natural sand, i.e. fine aggregate resulting from natural disintegration of rocks. ii) Crushed stone sand, i.e. fine aggregate produced by crushing hard stone.
Various researchers are developing efforts to integrate waste and by-products as alternative materials in road construction and maintenance, reducing …
