The lower rutting depth of the steelslag mixture can be explained by the fact that steelslag interlocks well within the mixture, which is undeniably essential for deformation resistance. Thus, for ACB28, using steelslag as an aggregate replacement could cater for a
concrete development. The present research work deals with a view to develop efficient concrete by addition of steel slag to evaluate the effectiveness of the use of steel slag as a partial replacement in sand To replace Sand with various percentages 10, 20, 30, 40% of steel slag waste in M25, M30 amp; M35 concrete. Investigation have
Aug 29, 2020#0183;#32;The result shows that 40% replacement of steel slag with 20%of walnut shell gives better flexural strength for water curing to the 7 and 28 days. Also 50% replacement gives better compressive strength. But 40% replacement is desirable and economical replacement of steel slag as
An experimental study was conducted to investigate the influence of steel slag by partially replacing coarse aggregate in flyash based geopolymer concrete. The mechanical and flexural properties were tested with steel slag in proportions of 10%, 20%, 30% and 40% in geopolymer concrete after 3, 7
Workability of Slag replacement concrete is higher than control mix and well as showed the better cohesiveness. The compressive Strength of concrete at 28 days is increased by % for M20 and % for M30 when the fine aggregate replaced by slag by 45% and further increase in replacement decrease the strength.
and steel slag aggregate as alternative aggregate in concrete production. Concrete of M20 grade was considered for a water cement ratio of using 1:2:4 mix ratio, slag aggregate replacements were observed from 0 to at interval of 10%. The results of experimental investigations carried out to evaluate the fresh and hardened
The use of blast furnace slag aggregates in concrete by replacing natural aggregates is a most promising concept because its impact strength is more than the natural aggregate. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance
The replacement of 100 % slag aggregate (coarse) increased concrete density by about 5 to 7 % compared to control mix. The study concluded that compressive strength of concrete improved by 4 to7 % at all the % replacements of normal crushed coarse aggregate with crystallized slag.
environment. Steel slag was used as an aggregate replacement in conventional concrete mixes. Steel slag which is mainly consists of calcium carbonate is produced as a byproduct during the oxidation process in steel industry. Steel slag was selected due to its characteristics, which are almost similar to conventional aggregates

Aug 08, 2020#0183;#32;The increased proportion of traffic volumes on roads is often the cause of distress to the pavement structure. The use of strong and durable steel slag (S) as an aggregate material in asphalt concrete can enhance the loadbearing capacity while at the same time conserving natural resources, resulting in a sustainable asphalt pavement system.
The applications of steel slag powder and steel slag aggregate in ultrigh performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results show that the fluidity of the paste containing
The results indicated that the highest concrete strength was obtained for the mixtures possessed a percentage of % steel slag aggregates as a replacement of the coarse aggregate.
EFFECT OF STEEL SLAG ON THE PROPERTIES OF CONCRETE 67% steel slag aggregates as a replacement of the coarse et al. (2016) in their experimental study on the use of slag
Steel slag is an industrial byproduct of steel industry. It possesses the problem of disposal as waste and is of environmental concern [9]. The demand for aggregate in construction industry is increasing rapidly and so is the demand for concrete. Thus it is becoming more important to seek suitable alternatives for aggregates in the future.

with substantial replacement of natural aggregates and natural sand used in concrete. In this study coarse aggregate were partially replaced with steel slag aggregate with different replacement percentage in concrete 0%, 10%, 20%, and 30%. In which we found compressive strength of
replacing about 10%, 20%, 30% and 40% of steel slag aggregates by volume for Msand will not do any harm to concrete and also it will not have any adverse effects on the strength and durability. Key Words: steel slag, partial replacement of fine aggregate 1. INTRODUCTION Steel
Aug 08, 2020#0183;#32;The use of strong and durable steel slag (S) as an aggregate material in asphalt concrete can enhance the loadbearing capacity while at the same time conserving natural resources, resulting in a sustainable asphalt pavement system. This research evaluated the feasibility of using S to replace natural limestone (L) at various aggregate sizes in asphalt concrete.
Dec 25, 2017#0183;#32;In this study steel slag aggregate processed by several aging process was comparatively satisfied with fundamental properties as concrete aggregate, which are specific gravity, absorption, unit weight, percentage of solids and abrasion value etc. Chemical analysis is also observed to understand the effect of aging process in steel slag aggregate. When the strength is measured, it is found that the concrete replacing crushed stone
Modification of concrete properties by the addition of appropriate materials is a popular field of concrete research. In this study we are focusing on the use of selected waste of steel industry (steel slag) as a partial replacement for fine
Slag has been used as an addition to concrete up to 70 percent by weight of coarse aggregate. It increases the water demand in a concrete mix; however, dosage rates of less than 5 percent will not typically require a water reducer. High replacement rates will require the use of a high range water reducer.
